Your MacOS also uses cached data to run quickly and efficiently.Īlong with physically cleaning your computer, internal maintenance - like clearing your caches- is essential to keep your Mac running at its best.Ī build-up of cache files from old websites or apps you never visit can eat up space and slow your system down.
Your Mac uses cached data for both Apple’s built-in apps and third-party apps. Each one uses different cached files to provide you with the best possible user experience. There are three primary types of caches: system cache, browser cache, and application cache (also known as the user cache).
The next time you log on, those images and videos are ready and waiting in your browser’s cache.īut do you really need to save all those pictures of your old high school friends, baking tutorials, and all the rest? Large cache files - images, videos, other multimedia, and scripts - can clog up your storage space if you never clear your cache. When you visit Facebook or YouTube, your browser saves some of the data (images, videos, and more) in the cache.
