hi,
I am ahmed, I am using MacBook Air. Today I am trying to change my admin name but I can't. when I try to unlock then I put the right user name and password but I can't. kindly suggest to me how can I solve this problem.
Hello, Ahmed.
Sorry to hear you're having this trouble with your Mac.
I suggest you restart the Mac and try again. Very often a restart can overcome little glitches like this.
If rebooting your Mac doesn’t fix things, see if the problem still happens in Safe mode (hold the shift key down at startup). It can take much longer (10 min) to safe boot so be patient.
How to use safe mode on your Mac - Apple Support
Safe mode forces the OS to clear certain caches and logs and do other miscellaneous housekeeping. It's non-destructive to user data so is safe to do. Very often certain weird software behavior is corrected by simply logging in this way as a troubleshooting method. When you're in safe boot, the machine will not be at its best performance, especially with graphics, but that's normal.
Does the problem persist while in Safe mode?
Exit safe mode by restarting your Mac normally and re-evaluate the issue again.
