What are cache folders

macOS Mac: clear the cache - that's how it works

display

"Cache" is French for "hiding place" and in IT means data that is not visible to the user but is stored in the background. These serve to accelerate tasks and processes. If too much background data accumulates, however, it can also slow down your computer. The macOS High Sierra operating system automatically deletes both cache and temporary files, so that no or at least very little unused data should be floating around on your computer. In order to free your memory from unnecessary ballast, to fix errors and, if necessary, to make the system a little faster, it is still worth manually emptying the cache. We'll show you how to do it.

Note: Create a TimeMachine backup beforehand so that you can restore deleted data in an emergency.
