Cache

Three different things get called cache on a MacBook Air, and most people asking this want the browser one. Here is how to clear each of them in Safari, Chrome and macOS, plus the part cleaner apps skip: clearing cache almost never makes a Mac faster.

Slack, Discord, VS Code and Spotify can hoard multi-GB caches. How to clear app caches on Mac safely: quit the app, empty only its Cache folder, skip real data.

Is it safe to delete cache on Mac? Mostly yes for user caches in ~/Library/Caches; macOS and apps rebuild them next launch. Which to clear, which to leave.
