I'm trying to use OCLP 1.4.2 to upgrade my 2013 Mac Pro trash can (3.0 GHz 8-core, 32 GB, AMD FirePro D700 6 GB) from Monterey 12.7.4 to Sonoma 14.4.
Ran the OCLP patcher, told it to download Sonoma 14.4, it created the USB installer OK (on a 32 GB SanDisk Ultra USB 3.0 USB stick). OCLP built, I told it to install to the EFI partition on the boot volume. Rebooted, held down Option, picked the EFI partition, and on the next screen I picked the USB stick.
Screen blanks, the Apple logo comes up, a couple of ticks on the progress bar ... and then, nothing. Screen goes blank, and my LG 5K monitor (connected via Thunderbolt, with an Apple TB3 -> TB2 adapter - works fine when booted into Monterey 12.7.4) says it's going into Power Save mode. Power-cycled, same steps, same result.
When booted into Monterey 12.7.4 if I go into the USB stick and double click on the "Install macOS Sonoma" app it comes up fine. I don't dare tell it to run because I'm not booted from the OCLP EFI choice.
I have no clue why the Sonoma 14.4 installer goes off into the ozone when picked from the Option boot picker.
Any ideas?
