Vuze For Mac Os Big Sur

Posted on  by admin
  1. Catalinaで動いてたEasyDrawがBig Surで動かなかったり。 俺も、ココ半年解決に時間を要したよ! だからCatalinaとBig Surと2台体制なのだ。 M1 Macの買い時を逃してしまい、今はM2 Mac待ちなのだ。.
  2. Nov 15, 2020 I updated to mac OS Big Sur 11.0.1 and now my computer will not connect to the Canon copier/printers at my school. This is a huge problem. Tech department says the only fix is I have to back up my computer and then bring it to them and they will wipe it and download the older operating system. Then I can reload my computer.
  3. This video will be about macOS Big Sur and how to install it. Download CleanMyMac X to prepare your Mac for macOS Big Sur:Part 1.

Torrent, named after BitTorrent, is a file sharing protocol which allows files to be fragmented and downloaded from multiple sources called peers. Although the word “torrent” has been long associated with illegal piracy and forbidden files, the torrent file itself is simply an instruction set of where to find those file fragments, so they can come together to form a whole. All the fragments are hosted by other computer users connected to the torrent network, such as yourself.

Best torrent clients for Mac

Get a huge set of downloaders for your Mac. Best utilities in one pack, give it a go!

It might sound complicated, but peer-to-peer is actually a very smart and efficient way to share files that don’t rely on single servers or private storage. Mac Torrents are no different to their PC or Linux counterparts. The only thing that isn’t the same is the choice of torrent clients themselves.

What is a Mac torrent Client?

As torrents became popular, the stigma around their use was diminished. Users worldwide were surprised at how quickly they could download files without experiencing the paywall or slowdown of traditional file-sharing systems.

To start downloading files through torrent, you just need to download and install a torrent client (software). The torrent client will then follow the instructions given in the torrent file to complete your download. Think of it like a download manager, specifically built for torrent files.

Torrent Mac clients come in different shapes and sizes, but all ultimately do the same thing — download files (called leeching) or upload files (called seeding). The right torrent client for you depends on your needs. You can opt for small and simple, or look for something more complex boasting advanced features. Downloading and installing a torrent client isn’t illegal per se, but all users should be wary of some nuances.

Is a torrent downloader for Mac legal?

Although torrents have historically been seen as illegal file-sharing systems, they are not inherently illegal at all. Torrent clients have many legitimate uses, including the sharing of open-source software or publically available files. The advantage of using a torrent client in these situations is potentially faster download speeds, especially if you use the best torrent downloader available.

Assuming the files you’re downloading aren’t subject to copyright or distribution laws, there should be no cause for concern. Conversely, if you’re using the torrent client to download files that you’d normally have to pay for, you may be breaching legislation, depending on the jurisdiction you reside in.

What to look for in a torrent Mac client

When it comes to reviewing a torrent downloader for Mac, there are a few considerations to take into account. At a high level, a basic user who runs the torrent client to download files infrequently will be happy with the most basic, lightweight app, and they don’t necessarily need the best torrent software. Those who wish to contribute and share their own files, or spend a lot of time downloading and uploading, might want to enjoy some of the advanced features available. For example:

  • Bandwidth limiters allow you to throttle your download or upload speed to ensure your internet connection remains available for other tasks, or to ensure you don’t use all of your internet data.
  • Magnet URI functionality lets you begin your Mac torrent download from a link rather than physically downloading a torrent file first.
  • Encryption helps to mask the torrent activity to throw off your ISP monitoring and enjoy full-speed downloads in the case of ISP throttling.
  • Superseeding enables you to become an uploader much faster after a download, but carries a risk of failing the upload if there’s only one downloader on the other end.
  • Pricing can either turn on some advanced features, extra security, and ensure no advertising, or offer you a basic torrent client for free.

As you can see, most of the features separating various torrent clients are generally of a more pro-level nature. For the majority of basic users, they are less important than the look and feel of the torrent app. So what’s the best torrent client for Mac? Let’s dive into the pros and cons of the most popular Mac torrent clients so you know where to pull the trigger.

BitTorrent and uTorrent

BitTorrent for Mac is one of the original torrent clients designed to implement the BitTorrent protocol. It comes with the advantage of many years of experience and updates under the hood.

Strangely, BitTorrent also owns and operates uTorrent, another leading client. At face value, they are essentially the exact same software, right down to the user interface.

The key difference between the two apps is that BitTorrent for Mac only releases stable, tested versions, whereas uTorrent releases alpha and beta versions for those who wish to test out the latest features before everyone else. The early releases can beg the question: Is uTorrent safe? When it comes to subscribing to alpha and beta builds, it’s a matter of buyer beware — best for advanced users.

Another key difference is that uTorrent is slightly smaller than BitTorrent, and therefore easier to launch and less taxing when running a Mac torrent download.

Generally speaking, uTorrent still might be the better option for basic users who download torrents infrequently, simply because of its simplicity and lightweight build. Just hope those betas are stable enough!


  • Small and lightweight
  • Ability to schedule downloads
  • Long history of reliable updates


  • Contains ads (!)
  • Both clients are susceptible to some security issues

Vuze and Vuze Plus torrent for Mac

If BitTorrent and uTorrent are the small, lightweight clients that get the job done — Vuze is created for the more advanced user who wishes to enjoy extended functionality.

The key difference here is the ability to add plugins for new features. Vuze comes in two versions. The first is Vuze Leap and the second Vuze Plus, which is essentially the same except for professional virus protection and the ability to preview files as they are downloading. Vuze Plus is also a paid client with all ads removed.

Vuze in general is likely a more suitable candidate for tech-savvy users who wish to take full advantage of the expandable plugin functionality. When set up correctly, it can be a top candidate for the best torrent downloader for Mac.


  • Expandable functionality through plugins
  • Simple interface that borrows from the best
  • Vuze Plus features added security


  • Contains banner ads unless in paid version
  • Two versions can lead to confusion

Folx Pro – the best torrent client for Mac?

Folx Pro is a paid torrent client, which means there are no ads and it comes with some great security measures right out of the box. Folx covers all of the basic features you would want in a torrent client, including scheduling. You can even search for new torrent files to download from within the client, instead of having to browse the web.

Additionally, Mac users will appreciate the look, which takes after macOS and feels right at home. The interface is beautifully simple — refreshing after the added visual noise of competing Mac torrent clients.

Downloading with Folx Pro is thus even simpler than with other apps:

  1. Use the top search bar to type in your keyword and hit Return
  2. Wait for all results to show up
  3. Choose the appropriate file and click Download on the right-hand side


  • No ads whatsoever
  • Built-in security measures
  • macOS-inspired design


  • Paid version only

Maintain your security at all times

One of the most important considerations to keep in mind when downloading torrent files is the risk of viruses or malware. Because there’s no single owner or distributor of the file at hand, it’s very easy to upload malicious files and escape the liability or consequences of doing so. Often, hackers will hide malicious software or scripts in popular torrent files. In these cases, it’s best to try to download torrent files that are distributed from a trustworthy source. Additionally, the best torrent software should come bundled with some security measures.

In any case, it’s a good idea to always scan your Mac for viruses. Thankfully, there’s an easy to use app called CleanMyMac X which will not only scan your system and quarantine malicious files but also optimize your Mac and help you properly configure your privacy settin

To quickly check your computer after every torrent download with CleanMyMac X:

  1. Open the app and navigate to Malware Removal tab under Protection in the sidebar
  2. Click Scan and wait for the process to finish
  3. Remove any malware found

Now that you know what Mac torrent clients are and some of the features to look for, you’re ready to get started with your unlimited file sharing. It’s recommended that you lean on the side of caution though, so a paid torrent client is your best bet.

Thankfully, you can try both Folx Pro torrent app and CleanMyMac X virus scanner for free during a seven-day trial with Setapp — a subscription service for Mac that grants you access to more than 150 indispensable apps to enrich your digital life. What are you planning to download now?

Release Issues[edit]

No outgoing connections[edit]

If you have configured an unlimited torrent connection limit (Tools->Options->Transfer: per-torrent or global peer limits) then there is a bug that prevents outgoing connections from being attempted (incoming will be accepted). You can fix this by configuring a large limit (e.g. 1000) instead of using '0' to denote 'unlimited'

Release Issues[edit]

Windows installer/runtime error on upgrade[edit]

After running the update installer and subsequently starting Vuze you may receive the following error message:

The solution is to run the installer from - don't uninstall Vuze just re-install.

This issue is fixed for new updaters.

Vuze crashes on start[edit]

Although not definitely tied to the release itself some users are experiencing a crash when starting Vuze. See Vuze_disappears#SWT_Browser_Issues for an overview of the problem and a workaround. Normally you would join the Beta_Program to install the latest updates but if Vuze crashes on startup you won't be able to do this - please manually install the update from

Once on the latest beta Vuze should automatically disable the internal browser and hopefully run successfully. If not please try manually disabling the browser by creating some Configuration Presets. You will need to enter the following into the presets file:

Non Issues[edit]

Restructured library context menu[edit]

Not an issue, but if you really can't get used to the new context menu then you can enable the old menu by deselecting Tools->Options->Interface->Table: Library: Show fancy menu.

Note that the existing top level Torrents menu (enabled via Tools->Options->Interface->Display: Various: Show the Torrents menu) also uses the older menu style.

Occasional ding sound when running Vuze[edit]

The new Chat feature plays a sound when a new message is received and you don't have that chat window open. You can disable this - see Decentralized_Chat#Notifications

The default has been switched by patch for users so you will need to turn the notification on if you want it

Inability to switch back to the non-fancy library menu[edit]

Unfortunately the ability to switch back to the old-style menu was broken in This is corrected in 5601 B03 and above so if you need to switch then please join the Beta_Program

This issue has been patched for users so you should now be able to switch menus successfully...

Release Issues[edit]

Linux UI Issues[edit]

  • UI components fail to draw correctly

5500 required an update to SWT to version 4508 to function properly. There are two versions of GTK at large, the older GTK2 (which Vuze has worked with for a long time) and the newer GTK3. Unfortunately there are major issues with GTK3 and Vuze at the moment (the sidebar doesn't draw correctly, SWT Group items don't render, the 'open-torrent-dialog' is a mess). So for the moment at least we force GTK2 via a new directive in the startup script:

export SWT_GTK3=0

If you are having issues please ensure that your SWT is version 4508 (check Help->About) and that your startup script has this entry (this should automatically be added on upgrade)

This has resolved problems for some users but there are outstanding problems with CentOS 6.6 + metacity

  • Vuze crashes when opening dialogs (such as the open-torrent dialog)

If you are using 'Oxygen GTK' see for a work around.

Release Issues[edit]

Torrents reporting 'Network not enabled'[edit]

After updating some users are finding some of their torrents report 'Network not enabled' against the torrents' tracker status. This is for public trackers (http(s) or udp ones).

This has most likely been caused by the fixing of a bug that was causing the network enabled state to not be checked correctly - when the torrent was originally added the 'Public' network was disabled, either because the default networks had been changed under Tools->Options->Connection (see near the bottom of this page), or by manually disabling it by right-clicking on the torrent, selecting Advanced->Networks and deselecting 'Public'. Note that since 5400 the networks can also be selected in the 'torrent options' dialog when adding the torrent.

If you have changed the default then go to Tools->Options->Connection and re-enable the Public network. This will NOT fix existing torrents though as they remember their enabled networks in force when added (or later changed). To fix this you will need to (multi)select the torrents you want to change, right-click on them and use the Advanced->Networks menu to enable the Public network.

You will also need to stop and start the torrents for them to pick up the change.

There is some more discussion on the forum:

Release Issues[edit]

Swing Web UI plugin broken[edit]

The 'Swing Web UI' plugin ( is broken and unfortunately needs an update to the core to work - please update to 5301_B02 or higher and make sure you have the updated plugin installed.

Release Issues[edit]

  • Vuze 5200 Windows installer, executable crash when ALSR is on; See Vuze forums Vuze 5200 Windows installer, executable crash when ALSR is on

Release Issues[edit]

Open Torrent window not showing when clicking on links in a browser[edit]

There is a bug in the way torrent links are handled when passed to Vuze from another process (for example, when clicking on a torrent/magnet link in a browser) that results in Vuze being activated but the torrent not being added to Vuze.

This is caused by an error in the code that prompts the user for the location to save the torrent file in.

It only happens when no default save location for torrents has been configured (by default this is configured to be a folder called 'torrents' in your Vuze configuration folder, so an explicit configuration change by the user is required to trigger this)

Work around is to define a default torrent save location: Tools->Options->Files->Torrents

Fix is in - see the Beta Program to access this.

General Issues[edit]


Vuze Won't Start[edit]

  • Java Versions Mismatch

This is most often caused by a mismatch between the type of Vuze installation you have and the type of your Java install. Both Vuze and Java come in two types, 32-bit and 64-bit. For things to work the two must agree - 32-bit Vuze needs a 32-bit Java and 64-bit Vuze needs a 64-bit Java. When you run the standard Vuze Windows installer you are actually running a 'stub' installer that works out which 32/64 bit 'real' installer you need and then downloads and runs it.

Sometimes things get confused and you end up with a mismatch of Vuze/Java types and things don't work.

If you can't figure things out then follow the instructions to remove all versions of Vuze and Java and then re-install Vuze.

  • Hola VPN conflict

By default Vuze uses TCP port 6880 to communicate with itself - once Vuze is running any other attempts to start Vuze (e.g. clicking on a .torrent file) will cause Vuze to send instructions (e.g. 'open this torrent') to itself via this port.

Unfortunately, sometime in early/mid 2015, Hola selected the same port to use in its software. So when Hola's service is running it grabs control of the port. This confuses Vuze into thinking it is already running and prevents startup.

You can fix this by uninstalling Hola or by telling Vuze to use a different port - see Command Line Options for an example of how to do this by editing the Azureus.exe.vmoptions file.

Multiple Copies Of Vuze Running[edit]

If another application (e.g. Hola, see above) has taken control of the port that Vuze uses for internal communications then this can result in multiple copies of Vuze starting. To fix this issue either locate the application responsible ('Resource Monitor' is a good tool for this) or change the port that Vuze uses (again, see above for the Hola fix)


Linux Unity Global Menu Issue[edit]

With Vuze 5600 and Ubuntu 14.04 (and no doubt others) Vuze will crash when using the global 'View' menu. This is caused by a bug in the SWT library that Vuze uses when handing 'radio button' menu items (used to display the simple/detailed library view state in the menu).

You can work around this by disabling global menus - edit the Vuze start up script to add


before starting Vuze - alternatively manually enter this into a terminal before launching.

There are various other ways of disabling the global menu within Ubuntu - see their documentation.

From Vuze 5600_B27 and onwards the menu has been changed to use check buttons which don't trigger the crash.

Linux Oxygen Theme Issues[edit]

Vuze crashes with the following when going to various views that use List widgets (e.g. the Logging section in Options)

/builddir/build/BUILD/oxygen-gtk2-1.4.5/src/animations/oxygencomboboxdata.cpp:87: void Oxygen::ComboBoxData::setButton(GtkWidget*): Assertion `!_button._widget' failed.

This is fixed in version 1.4.6 of oxygen-gtk2 (e.g. see

Linux Browser Views Blank[edit]

Internally Vuze uses an embedded web browser to display some views - for example search results. If these views are blank you may have success by installing webkit:

On Ubuntu this works up to a point - last time it was tested the search results page caused a crash in libwebkit... :(

Mac OSX[edit]

OSX 10.10 (Yosemite) Issues[edit]

As usual there is the issue with OSX upgrades removing previously installed versions of Java.

If you have an issue with Vuze not running after the upgrade we recommend you run the Java 1.7 installer from here:


OSX 10.9 (Mavericks) Issues[edit]

Occasionally an upgrade to 10.9 (also seems to apply to updates to Mavericks, such as going from 10.9.1 -> 10.9.2) will leave Vuze in a broken state - launching it does nothing, not even a bounce in the dock. This is caused by Mavericks not correctly determining that the upgrade has removed Java from the system and it needs to be re-installed.

Unless you previously manually installed Java 1.7 from, and installed the Java 1.7 version from Vuze from sourceforge (, you will need to install Apple's version of Java 1.6.

At time of writing this is available here: (Java for OS X 2013-005)

If you did install Java 1.7 then the latest version is here:

  • We have also had reports that a reboot of Mavericks can sometimes solve the issue where attempting to launch Vuze with no Java installed does not cause Mavericks to auto-prompt you to install a Java runtime

OSX 10.5 PPC Issues[edit]

  • Missing application menus
There are two SWT user interface libraries that are/were supported by Vuze on OSX - carbon (which was last updated in August 2010) and cocoa. PPC is also an old platform that can't be upgraded beyond OSX 10.5.
While the more recent releases of Vuze still run on OSX 10.5 PPC there is an issue with the cocoa SWT library that causes Vuze's menus to be displayed incorrectly. They are still there - click on the Vuze menu to open it and then move your mouse to the right along the menu bar area - the missing menus will expand (for example the Tools menu and the Help menu). If this is too annoying you can switch to the (old, less supported) carbon SWT library. Open Vuze's options (either use the menu trick above to get to the tools menu or use the shortcut 'apple-key+,' (press the apple key and the comma together). Then go to the Interface section and select Display - look for the drop-down that shows 'cocoa' and change this to 'carbon'. Save the config and restart Vuze. The carbon SWT library should download and install and then request a restart, after which things should be working.
You can tell which SWT library is in use by going to 'About Vuze' and looking in the 'System' box at the bottom right.


ESET Smart Security version 8: High CPU in Vuze[edit]

It seems that this version causes somewhat high CPU usage to be indicated against Vuze. This can be seen by checking the thread_1.log (or thread_2.log) files in the Vuze configuration folder's 'logs' folder - the most active thread will often be flagged as 'PRUDPPacketHandler:sender'. This is normally a low resource thread that is responsible for dispatching UDP packets. It would appear that ESET's in-procress interception and analysis of such UDP data is inefficient and causes high CPU usage.

Vuze Macos Big Sur Not Working

Adding Vuze to the ESET exceptions apparently fixes this.

SSL handshake errors[edit]

Some sites are moving to using 256 bit AES crypto only. By default Java does not support this level of encryption, you will need to manually install the 'unlimited jurisdiction policy files'. See


Some users are experiencing an SSL related exception of the form: unable to find valid certification path to requested target

Please ensure that your Java is up-to-date (either re-run the Vuze installer from or, if you are using the system installed Java, update from

If the problem persists then go to Tools->Options->Security and hit the 'Reset certificate store' button and restart Vuze

Vuze For Mac Os Big Sur Download

If the problem still persists then it may be caused by Vuze failing to auto-install a server certificate after following an HTTP redirect (in all versions up to For one site where this is know to occur the issue can be fixed by manually opening the following (non-existent) torrent in Vuze

and waiting for the process to complete. Once this is done the SSL certificate will have been installed and other torrents that follow a redirect will subsequently work.

Alternatively install the latest beta (5721_B11+ - see Beta Program) to get an updated version which resolves this issue.[edit]

If you see the following exception when downloading resources over HTTPS such as torrents and subscriptions Error constructing implementation (algorithm: Default, provider: SunJSSE, class:$DefaultSSLContext)

then you can try to fix this by either joining the beta program and installing 5721_B20+ (see see Beta Program) or by manually resetting your certificate store by going to Tools->Options->Security, hitting the 'Reset certificate store' button and restarting Vuze. Received fatal alert: internal_error[edit]

This can be reported when you are running an old version of Java and/or Vuze - first make sure you are fully updated to the latest version of Vuze. Then check that your Java version is at least 1.8. You can see your current version in the 'About Vuze' window. Java can be updated by going to If after updating the problem persists double check the Java version again. It is possible that Vuze is using a non-system version of Java. This is a particular issue on Mac where Apple's own legacy version of Java is version 1.6 and won't ever be updated. If this is the case you need to switch to the Oracle version by using the correct installer from

Torrent download fails with 'Server returned HTTP response code: 503'[edit]

This can happen when the website that hosts the torrent file employs Cloudflare DDOS protection. When this is enabled Cloudflare employs various browser based checks (for example, via JavaScript) to attempt to detect that a person is accessing the website as opposed to an automated process. In this case Vuze can't directly download the torrent as it fails the 'is a person' test and Cloudflare returns error 503.

To work around this manually enter the torrent download URL in a web browser, download the torrent, then add it to Vuze directly.

Here's an example error message that shows the issue:

Error : Failed to download '' to '12345': Server returned HTTP response code: 503 for URL:

To work around this open your web browser and paste in the download URL ( Then locate the .torrent file that has been downloaded and drag/drop it onto Vuze. Alternatvely use the 'Open Torrents' button at the top-left of Vuze, select the 'Add Files' button and browse to the .torrent file.

5741_B10 has a work around for this issue for the case where a torrent hash is available - when the initial download fails it will be retried as a magnet download. In the search results view this requires you to switch to the 'Native' results view using the button at the top of the results area. See the Beta_Program for details on how to get this.

iTunes Integration Problems[edit]

Although not specific to a particular release a number of users are reporting that the iTunes icon in their sidebar shows a yellow warning triangle with a tool-tip indicating that there are integration problems. See iTunes Tips for a potential solution to this on Windows.

Non Issues[edit]

Side Bar has Vanished![edit]

The sidebar is the 'tree' view normally present on the left-hand-side of Vuze, the top entry is 'My Torrents' and under this 'Library' etc. Within the Vuze UI this can naturally be hidden/restored by pressing F7 (or using the View menu's 'Side Bar' option) - it is replaced by two small UI components; one restores the sidebar when clicked, the other gives a menu view of the sidebar components.

There is also a separate Vuze user interface known as the 'Classic UI' or 'Azureus Experience'. This does not have a sidebar view at all.

Users occasionally switch between the regular Vuze view and the Classic UI by accident and then wonder where their side bar has gone. This can be remedied by

Internal Browser Is Disabled[edit]

Vuze uses an embedded browser component to display web content within the application itself (via the SWT UI framework). On Windows this uses Internet Explorer (on OSX Safari and on Linux Firefox if configured correctly). Unfortunately, a crash in the browser code causes Vuze itself to crash. This is a particular issue on Windows, there seems to be some users with an Internet Explorer configuration that triggers frequent crashes (exact cause unknown, perhaps browser extensions that these users have installed?).

Mac Os Big Sur Download

To improve the stability of Vuze, from version 5600 onward, Vuze will look for evidence of previous crashes caused by the browser component and automatically disable its use. When this happens you will see a message to this effect within Vuze when navigating to views that use the component.

Mac Os Big Sur Problems

To re-enable the browser you need to

  • ensure that your 'mode' is set to 'advanced' under Tools->Options->Mode
  • enable the browser by unchecking the 'disable all use of internal browser' under Tools->Options->Interface->Display: Internal Browser
  • restart Vuze
