Updating the mac system
You want a directly connected network connection, ideally without any restrictions to access.
Now boot up your Mac Book again and tell it to restart and try to update the software again. Let it work out any kinks, and see if it can now load Mac OS successfully.
The best way to deal with this is to reinstall Mac OS entirely. You don’t have to erase your disk to do this, which means you should be able to keep almost all your saved data (which is unlikely to have caused this particular problem).
When turning your Mac on, simple hold down the “Command” and “R” keys to get started. From here, choose “Reinstall Mac OS.” When prompted, choose “Continue” and follow the instructions to complete the reinstallation.
This problem is often traced back to Mac Books that have the Touch Bar.
The Touch Bar acts much like a built-in accessory, and has specific firmware dedicated to its operation.
If you can access Mac OS, even for a few minutes, then you can try deleting recently installed apps and see if this fixes the problem.
As always, it’s strongly recommended to back up a Mac before installing any system software update.This is often just the special treatment that the Touch Bar update needs.Kernel panic and update issues can be caused by a recently downloaded app that is working very poorly with Mac OS.Want to check for software updates in Mac OS Mojave?Perhaps you’re wondering where system software updates went in Mac OS Mojave?
