How to fix 'a critical software update is required' error on Mac by forgetting the network in safe mode?
OMG. I have a MacBook Pro and have been dealing FOR MONTHS with the following error when booting my computer.
"a critical software update is required for your Mac, but an error was encountered while installing this update. Your Mac can’t be used until this update is installed.”
The only way I was able to use my computer was in safe mode and it's pretty much impossible to do anything.
I saw the solution on an obscure developer blog and I wish I had the name of the person to credit. The solution they suggested sounded too good to be true but IT WORKED AND IT IS EASY!
SO....DRUM ROLL.. To fix this error, all you need to do is boot your computer up in safe mode (press the left shift key at start up). Next, go into the network settings and simply "forget the network". On my MacBook, I had to go into System Preferences and then Network. Then I went in and unchecked the boxes to automatically join the network. After that, I rebooted my computer and it was back to normal.
After my computer started back up normally, I joined the network again and put in my password etc and rebooted my computer again. I honestly thought the error would come right back but it didn't! Ever since I did the fix above my computer has finally been working normally again!
I HOPE THIS HELPS!!!
