So i upgraded to the newest version on macOS Big Sur 11.7.8. And I tried to flash an os in to my 120GB ssd usb A drive. Everything went smoothly, but then it failed.
So I tried another os and it failed again. So I tried to format the usb drive to “APFS” and it didn’t work. so I tried to save it and it didn’t work. I tried to change the Cable and who didn’t know it didn’t work. so I tried other usb A drive and it did work, but it was an ordinary usb A drive.
Please Help Me.
