MrKaszka Posted February 28, 2022 Share Posted February 28, 2022 Hi, after upgrading from 12.0.1 to 12.2.1, macOS stuck into a bootloop. It restarts at random point during system boot. I am using EFI from Jake Lo, from this post: I changed SMBIOS to MBP11,4. 12.0.1 version worked fine. Link to comment Share on other sites More sharing options...
Administrators Hervé Posted February 28, 2022 Administrators Share Posted February 28, 2022 Start by updating your add-on kexts to latest versions. Link to comment Share on other sites More sharing options...
MrKaszka Posted February 28, 2022 Author Share Posted February 28, 2022 Thanks for the answer, unfortunately the update did not help. Additionally, I created a bootable USB with the system. With the current EFI (or after updates), it is impossible to enter the installation stage - it restarts at the same stage as after the update.

Moderators Jake Lo Posted February 28, 2022 Moderators Share Posted February 28, 2022 you'll need latest OC 0.7.8 Link to comment Share on other sites More sharing options...
MrKaszka Posted February 28, 2022 Author Share Posted February 28, 2022 I also updated opencore and fixed the differences in config.plist using OCAT. Unfortunately, the bootloop is still there. Using the same EFI, macOS 12.0.1 boots without any problems, while the installer or the system does not get up after the update Link to comment Share on other sites More sharing options...
