I've added more serial port notes (for EFI and macOS) at https://github.com/acidanthera/bugtracker/issues/1954

11.6.4 still not fixed. Only worked when booted from OpenCore, when natively booted freezes on progress bar with no entry sign.

What does without "serial/panic" mean?

The patch would have to be included as a quirk to work with arbitrary kernel versions since the distance between kprintf and printf may change.

Or you could make a patch in config.plist for a specific kernel.
Apply the patch to a copy of the kernel, then compare the modified kernel with the original to create the patch.

Consider trying FireWire kprintf?
Or you can add a serial port card which can even work for Thunderbolt Macs.

I was asked to post in here by MacSoundSolutions... I installed OCLP and Mac OS 12.7.3... no boot screen - monitor says something like "input not recognized" and then about a half second before the login screen appears I will see the black screen with white apple logo. I followed the instructions to install enableGOP and seem to have successfully done so, however there are no changes. Computer works fine, just no boot screen. Prior to 12.7.3 I had 10.14.6 installed and instead of "input not recognized" the monitor just acted like the computer wasn't on yet.
