Error updating Mac OS
I had to update my MacBook air to Mac Big Sur (previously i had mojave) as I had to back up my iphone and was unable to as my Mac Os was too ‘old’. While trying to update an error has occurred, I have already restarted my mac a lot of times and whenever i restart it it automatically goes to the update mode and the error message pops up again. I am unable to access my mac or any files in it at all as it automatically goes to the update page whenever i restart it and there is always an error when its updating.
i am a student and i it is very important for me to access my mac and its files but i am unable to do so. What should i do?
i have attached a photo of the error measage
