Logic Board Failure after OS update
I was tring to update my macbook pro to BigSur 11.6 from 11.5 and after lot of downloading and installing error I finally completed process on the 5th go. And the next time I opend my mac its just a black brick, it only works after SMC restart. I visited the service center and the told that its Logic Board issue and need to change it. How this issues occurs after updation? Any thoughts?
