iMac won't boot after using migration assistant to new mac studio I got a new mac studio so I used migration assistant to move everything from my older (I think it's a 2015) iMac onto the new computer. migration worked well but now I can't get my iMac to boot up. It will show the apple logo then when the bar is about half loaded it shuts down. It won't boot in safe mode. I have gotten to the disk utility and it keeps saying it can't repair the Mac HD drive and it can't erase it either. It also shows that the HD drive is not mounted. What do I try now?
