I've got a Mac mini for temp/freelance staff to use while they were working in the office.
After a few years there's quite a few accounts on the Mac mini which are no longer required.
I don't want to delete them as there may be useful data in there, but I don't have time to do a full check/audit.
Is it possible to hide an account from the login screen where you can see all the users?
The mac mini is running macOS Sierra.
