How to Clear Your MacBook Air’s Cache?

Are you a MacBook Air user? Have you noticed that your MacBook’s performance is becoming slower with time? Well, then it is time to perform a MacBook Disk cleanup.

Along with many other MacBook users, you save email attachments, use applications, browse data on the net, chat via messengers, create playlists, and so on. As a result, your hard drive becomes full of junk after its’ daily use. Some of these junk files are caches, which can be removed from your MacBook with a snap of your fingers. In this post, you’ll get to know what cache is, how to clear cache on a MacBook Air, and what is the best way to do that.


What Is Cache?

Simply put, a cache is a type of temporary files that enable the macOS operations to work faster. There are different categories of cache files: browser cache, system cache, and user cache. For instance, when you visit a website, the multimedia content is being stored automatically on your MaсBook. Consequently, the next time you visit this website, the cached content would be re-used for faster performance. A similar process occurs when you use software on your MacBook Air. Some supporting files are stored on the disk and re-used to provide a proper function for a Mac.

Although these cache files are helpful, they are temporary files and may take up much space on a MacBook Disk. So, if you want to clear cache on a MacBook Air, there are two options to do so: manually and via special software.

Clear System Cache and User Cache

The next categories of caches files are the system cache and user cache. They are related to the daily operations of your Mac.
For instance, when you listen to music or play a video in iTunes, it stores the data as a cache file on your MacBook. These cache files are kept in the Cache folder in the Library. Over time they can take up a large amount of space on your MacBook disk. Besides that, cache files may become corrupted in some way and affect the iTunes’ software performance.

  3. Click Go in the Finders menu and select Go to Folder.
  4. Type ~/Library/Caches in the window currently displayed and click Go.
  5. Find the Cache folder of a specific app, select items in the folder and move them to Trash.
