RyckP | 5 years ago | on: macOS Big Sur Update Bricking Some Older MacBook Pro Models
Reading here about bricked MBPs. Could someone clarify for me. If one swaps out the SSD with the current OS and puts in a blank replacement and then do the update. If it fails will the MBP be bricked or can one just swap in the other SSD to get it operational with the older OS. Or can the update really brick it because hardware is flashed? If that's the case could that be re-flashed by someone with the right equipment and knowledge. Some people have upgraded to Big Sur on their 2011 and mid 2012 MBPs. What is the risk of bricking then?
