Then your two options are to perform a clean install by following the instructions in this Apple article making sure to follow the "Erase Disk" link within that article as well:

Erase Disk link:

If you have access to another qualifying Mac from 2013 - 2022, then you can create a bootable macOS USB installer using the instructions in this Apple article:

How to create a bootable installer for macOS - Apple Support


A "Qualifying Mac" means the host Mac being used to download the installer must also be able to run that version of macOS, although the host Mac can currently be running any version of macOS. For example you can create a bootable macOS 11.x Big Sur USB installer using most Macs from 2014 - 2020 (even a couple from late-2013), while you will generally need a Mac from 2015+ for creating a bootable macOS 12.x Monterey USB installer. See this article for which versions of macOS are compatible with various Apple hardware:

If that still fails, then you will need to "Restore" the system firmware (requires access to another Mac running macOS 10.15+):

Revive or restore a Mac with Apple silicon using Apple Configurator - Apple Support


If none of this works, then you will probably need to have Apple or an Apple Authorized Service Provider examine your laptop to assist you.

It helps to know the exact model of your Mac since different Macs have different issues and can behave differently. Plus some Macs require certain procedures while others do not. You can get this information by entering your serial number here:

Check Your Service and Support Coverage - Apple Support


Did you try Internet Recovery Mode using Command + Option + R (Intel Mac only)? Did you erase the whole hidden Container when performing the clean install (or the physical SSD if an Intel Mac)? Within Disk Utility you may need to click "View" and select "Show All Devices" before the hidden Container or physical SSD appears on the left pane of Disk Utility. You can only erase the physical drive on an Intel Mac. If you erase the physical drive on an M1 Mac, then you will make it unable to access the special startup modes. Another reason to always post the exact model.


If this is a 2018+ Mac, then you can "Restore" the system firmware instead (requires access to another Mac running macOS 10.15+):

So after performing the Restore of the firmware you were presented with Setup Assistant helping you set up the new OS?


Did you actually try creating a new user account and testing before trying to set things up? Or did you just migrate or restore from a backup? If the latter, then perhaps you brought the problem back. If you did not migrate/restore from a backup how did you set up the computer?


Is this a normal macOS login screen or another type of screen asking you to authenticate for some other reason?


Try booting into Safe Mode to see if that works any better.

I downloaded bigsur os ipsw file and restored using it. After restore activated macOS with Apple ID. Restarted system and created new user account. Login was successful. Did shutdown. Restart and loading is fine. After Home Screen getting error warning pop up “Your system was restarted due to problem”. I clicked show details. It shows panic “hide/restart timed out”. Report to Apple. I don’t have any other issues. I can use MacBook as usual. Thanks for help and support. Much appreciated.
