Why Can't I Log Out of My Apple ID/Apple Account on Mac?

Sometimes, the sign-out button is greyed out and unavailable, meaning you can't click on it to log out. There are some simple ways to fix this problem, though. Here's a look at the best methods.

• Restart your Mac: Restarting your Mac will solve the bulk of the issues, often enabling you to press the button again. 
• Check your internet connection: Your Apple Account needs to communicate with the Apple servers. If you're not online, it may not be possible to sign out.
• Turn off an iCloud backup: If your Mac is currently using iCloud backup services, you won't be able to sign out while it's busy updating anything. Switch it off or wait for the backup to finish.
• Turn off Screen Time: One unusual error means that having Screen Time switched on can stop you from logging out. ClickSystem Settings>Screen Time>Turn Offto switch it off, then try again.
