Don't Touch These Files!

Files and folders you should never move or delete
When you find a hefty folder of files on your Mac with a name you’ve never heard of, don’t assume you don’t need it. As a rule, unless you’re completely sure, don’t delete files within the System or Library folder on your Mac unless they relate to a specific, non-Apple application. Never blindly get rid of fonts that the system uses, and never try to move your user account or any of the files within it from its original location.

Hands off, buster!
To find out more about a file you plan to delete, first look at where it’s located on your Mac. You can also select the file or folder and hit Command-I to show info relating to the file. In some cases, you may spot it within Activity Monitor (found in Applications > Utilities). If the file or name is listed as a System Process, it’s best to leave it alone.
