  1. Selling Computer Clear Memory

You still remember the first thing on your mind when you were buying your new MacBook that this Machine will always keep up with your pace and will never slow down on you. That’s exactly what these awesome machines are built to do. But sooner than you think, it starts slowing down. The first thing you need to know is that the performance of your Mac depends a lot on the memory usage on the device. We will talk about some of the ways to learn how to reduce memory usage on Mac and get it to maximum performance again.

Check Your Available Memory Usage on Mac First!

All the applications developed for use on Apple Machines are built to optimally use the memory available. But memory management for MacBook becomes critical when you open too many applications that are running simultaneously. This results in major memory overload.

Depending on the age of your Mac, it contains a small amount of special memory called NVRAM (Non-Volatile RAM) or PRAM (Parameter RAM). Both store settings used by your Mac to control the configuration of various systems and devices. Now in the page of OmniDiskSweeper at the very bottom at the left corner, you'll see a white file picture, press it and a window will pop out, select all the files by clicking ( Command+A) now right click on the touchpad, from the menu choose (Erase Using Clean my mac). Now Clean my mac will pop out and you'll see al the file you selected to. Click on the drive and select the Erase tab. Set the format value to Mac OS Extended (Journaled)and click the Erasebutton. After that has finished select the Partition tab. Type in a Namefor your hard drive and select how many partitions you want from the Volume Scheme. The usual setting is one partition.

Once you experience your Mac slowing down, you should start analyzing the memory usage. If you don’t know how to check memory usage on Mac, the best application to start with is the Activity Monitor. You can easily find this application in the Utilities or you can simply type the name of the application in the Spotlight window.

Activity Monitor: Helpful Tool in Analyzing Memory Usage on Your Mac

Activity Monitor is a built-in application in MacOS which tells you everything that is running on your MacBook. It gives you a complete overview of your MacBook’s memory usage. Here you can find out what applications are currently running and how much memory is being utilized by each of the applications. It is an excellent tool in analyzing the memory usage as it gives you plenty of details on the resources being consumed by any application, including the memory being used, Number of threads utilized by each app, CPU usage, etc.

What's more, ths Activity Monitor shows how you can add different columns to check a particular resource being utilized by an application and play with the statistics to shut down what you don’t need and that eats too much of memory. To illustrate a few, let’s have a look at the memory page of Activity Monitor.

The memory page is very informative when you understand all that it is showing to you;

Memory Pressure: This graph gives you the usage of memory over a period of time. You can set the Update Frequency and set the intervals. The right-most bar is the current memory usage, going back in time as you move to the left of the graph. The color of the graph shows the usage level.

  • Green – RAM Memory available.
  • Yellow – RAM Memory still available, tasked by memory-management processes (like Compression)
  • Red – RAM Memory completely used. This is the time where you should start shutting down some apps.

You can see the total installed RAM on your computer shown as,

Physical Memory: Total memory installed.

The part which you are really concerned about is the one marked as,

Memory Used: Total memory being used by the running apps and processes. Getting inside to have a deeper understanding of the memory distribution allows you to play with it and get the best performance.

  • App Memory: Total memory used by all the apps/processes.
  • Wired memory: As the name suggests, this memory is (virtually) hard-wired and you cannot make any changes to the processes using this memory. These are usually the primary processes of your Machine and they need the memory with the quickest access and cannot be swapped with the memory on disk.
  • Compressed: The MacOS will compress a chunk of memory in the RAM to make more space for the utilization of other apps. You can see the column of compressed memory to see how much actual and compressed memory is used by each process or application.

Swap Used: The MacOS will utilize some space on the disk drive of your Mac. This is used to free up physical space on RAM for the applications requiring more intense use of memory.

Cached Files: The MacOS keeps the recently closed applications as cached files for quick loading once you restart the same application. However, this memory is available to be used by any new application if the same application is not started.
