disasterinc Posted March 30, 2017 Share Posted March 30, 2017 I tried updating my e5440 from 10.12.3 - 10.12.4 and now it hangs on boot. The system ultimately freezes on the apple/progress bar screen. Turning on verbose mode resulted in the output in the attached snapshot (snapped just before the apple/progress bar screen reappears). I did nothing except accept the update, no other edits and changes. After the hanging on boot started, I later updated CLOVERX64.efi and drivers64UEFI folder (copied into the efi/clover directory from a thumbdrive as suggested by Jake) and that hasn't helped. Prior to the update the computer was working properly with no signs of any problems. My sierra install thumb drive boots fine and I can open a terminal window, for example. It's the SSD that I now can't get to boot. Unfortunately due to a stripped screw head I can't get into the laptop case, but courtesy of a linux live thumb drive I can access the efi partition. I'm stumped and google isn't providing any useful answers. Any suggestions of how to fix this problem? thanks - Jay Link to comment Share on other sites More sharing options...
Administrators Bronxteck Posted March 30, 2017 Administrators Share Posted March 30, 2017 try updating clover in case your version does not have 10.12.4 kernel support Link to comment Share on other sites More sharing options...
disasterinc Posted March 30, 2017 Author Share Posted March 30, 2017 Thanks bronxteck. I was able to get the machine to boot properly. I had to manually update clover and I missed BOOTX64.efi. Once I updated that file the machine booted fine. Link to comment Share on other sites More sharing options...
