[QUOTE="M915 Driver, post: 1952084, member: 406139"] I have a late 2020 M1 MacBook Pro running MacOS 15.5. This morning I plugged in a USB C hub with 2 external drives plugged into it. One drive would not moun, not even using Disk Utilitie. I shut down the computer and unplugged the hub. When I tried to reboot the computer it shows a circle with an ! In it. After going to the website on the screen, it seems the Firmware has been corrupted. iI understand that I need another Mac to revive or restore the firmware. I live in an assisted living facility and nobody here has a Mac. My question is is there a way to get this computer to boot without another Mac? Thank you for any suggestions Ken [/QUOTE]
