Is it safe to remove cache?

Generally, it is absolutely safe to remove cache because the apps you install or browsers you use will create new cache files when needed.

Cache defined

Cache is storage (or memory bank) that helps to quickly retrieve and collect temporary data tohelp your device, websites, browsers, and apps load faster. Whether it's a computer, laptop, smartphone, web browser, or app, you'll find some variety of cache.

What are the main cache types?

There are roughly three main types of caches on your Mac:

  • System cache

Mac's system cache is a memory bank that connects the main memory and the processor. This allows theCPU, or central processing unit, to retrieve data that your deviceuses to execute instructions quickly andwithout the need to load it bit by bit.

  • Browser cache

      No matter what web browser you use, they all have theirown cache. Those caches store files and their elements like HTML, CSS, JavaScript, cookies, or images that your browser uses to display websites. For instance, product page images, login information, shopping cart content, etc.

      • User cache (including app cache)

          Just like a web browser, the app maintains cache of its own. It helps quickly reload images, search history, videos, and other needed information to speed up and improve the performance and efficiency of the apps.
