Hi, I am trying to restore my previous backup in my 4,1 flashed to 5,1 Pro and am not able to. It was running 10.13.3 on an ssd and now when I wipe and try to reinstall the APFS backup my Mac indicates “running bless to place boot files failed”. I’ve wiped the drive and even tried downloading and reinstalling the OS but that failed as well with the same error. Does anyone have any ideas? If it helps my Mac is the quad 2,66ghz with 48gb of ram and has a flashed gtx 680 and a USB 3.0 Card inserted. The backup is from an old FireWire drive.
