How Does OS X Manage System Memory?

Standard and compressed memory management systems

In a standard memory management system, applications request an allocation of RAM and the system fulfills its request. Once the work is done and the app no longer needs the RAM, it is returned to the system.

MAC (Mavericks and above) systems, on the other hand, make use of compressed memory management system. It is mainly designed to increase performance by allowing the RAM to better manage resources. The OS looks for inactive memory, which is the memory not actively in use. But it holds data that will be used by an app. This inactive memory compresses the data within it, thus using less memory.

For instance, you have an MS Word document open while watching something on YouTube. Inactive memory (Word document in this case) is an app in the background and not in use. The OS compresses the Word processor’s memory to free up RAM for use by other apps. It is important to understand that the compression process is not performed at all times. Instead, the OS checks to see free space available in RAM. If there is enough memory left in the RAM with inactive memory in the background, no compression is done.

Despite the advantages of compressed memory management, MAC can still face issues with slow performance and crashes at times. You can work on the tips provided in this article to improve the performance of your MAC.

4 great tips to boost MAC system performance and free up hard drive space

  1. The latest version of OS X

Apple provides free upgrades of OS X for you to stay updated. These new versions help improve security and performance of your MAC systems.

  1. Switch to an SSD

SSD uses flash memory as opposed to traditional hard drives. These SSD’s do not make use of any moving parts, hence less prone to damage and last longer. They are also known for their superior performance and value for money. Thus, switching to an SSD can make a huge difference in your MAC’s.

  1. Increase your RAM

Use the Apple help page and buy a right type of memory for your MacBook model. Make sure to buy a memory with appropriate size and speed for your requirements.

  1. Clean your hard drive

To clean your hard drive you need to clean up files, folders, and applications. First look for old and unnecessary applications and uninstall them. You can also use the Activity Monitor and check the amount of CPU and memory each app is using. If you find that a particular app is consuming too much memory/CPU, you may want to switch to an alternate app if possible.

Secondly, to clean up files, look for large files using the Finder. To do so, open Finder and select the volume which needs cleanup. Then choose File > Find and in the drop-down menu, click on Other. Once the ‘Select a search attribute’ window opens, check file size box. Enter a value appropriate to your situation and delete any unnecessary files. You can also move them to an external hard drive to free up space.

In the process of cleaning up your hard drive, you may accidentally delete important data. If the files are large, they usually bypass the recycle bin. In such cases, it is hard to recover your data without professional help. Remo Recover is designed to help you recover lost or deleted data from hard drives.
