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.

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.
