I have a MBP 2015 that I upgrade to Ventura using open core about 8 or so months ago. All was well for a bit.
About a month ago, I was using it and the open core dialog popped up and asked about an update to sonoma, foolishly, i said yes...
Since then, it's essentially bricked..
It now stays on the apple logo screen with about 5% of the white bar filled, and won't go past it.
I've tried every combo of booting and got no where.
any help and suggestions would be so appreciated.
Ty in advance
