imac wont start
Hi,
I just updated to Big Sur. While loading the black screen with the white loading bar said, less than 1 min till complete. This sign lasted more that 45 mins. So, I hit the power off button, then I got the " blinking ? folder support.apple.com/mac/startup.
I tried the, option, command, P, R combo and it didn't work.
Does anyone have any tips?
Thanks
