How do i clear my cache on mac

In the Activity Monitor app on your Mac, click Cache (or use the Touch Bar). If you don't see the Cache tab in the Activity Monitor window, choose Apple menu > System Settings, then click General in the sidebar. (You may need to scroll down.) Click Sharing on the right, then turn on Content Caching.

You can delete cache files on your Mac without having to worry about it acting up. This is because the important files will just load back when needed. However, you have to be careful not to delete files that are important for running your system.
