My son is away at college. He decided to run an update on his MacBookPro11,2 from Sonoma 14.3 to 14.4.1 without first updating OCLP 1.4.2 to 1.4.3. Now he cannot boot.
I made him a thumb drive with Sonoma 14.4.1 on it to boot from and re-install Sonoma on the internal drive. This did not solve his problem.
I am thinking that what he will have to do is this:

I am thinking that what he will have to do is this:
- Boot from that same thumb drive.
- Hook up an external drive, which I will prepare here to boot on his system with the help of OCLP 1.4.3 (āBuild and Install OpenCoreā) and has OCLP in /Applications/.
- Install macOS 14.4.1 on that external drive.
- Boot his MBP with that drive.
- Launch OCLP 1.4.3 from the external drive and use Build and Install OpenCore on his built-in boot drive.
