<< Solved >> Majove 10.14.4 Update Results in Black Screen After Apple Logo Appears

[MacOrDie]

Went down in flames..

First the update worked with lot's of black screens, then rebooted and worked. I shutdown for the night.

However, on the next reboot, MacOS did a 44 minute install, no idea why and it boots to black screen after Apple logo progress bar.

When booting in verbose mode, the last lines are

busy timeout[0] (60s): 'AppleACPICPU'
busy timeout[0] (60s): 'AppleACPICPU'
busy timeout[0] (60s): 'AppleACPICPU'

then the screen goes black

Looks like a hint....
Going to try and update all the kexts and see what happens.

The great thing about a hack-in-tosh is how much you learn about OSX Internals. Soon I will be a OSX systems engineer.

If anyone has any words of wisdom, please share. Thank you!

I got fixed by upgrading clover to latest one ..

Which version did you use?

I tried 2.4k_r4862-UEFI.pkg

which resulted in the clover screen appearing faster, but still hanging at the

busy timeout[0] (60s): 'AppleACPICPU'

Did you change anything else? Thanks for your reply.

it is v2.4k r4910 EFI. I transferred all my kext to new clover and also config.plist. All good!

Thanks so much, that version is not on Tonymac's download page yet, so I will get it from SourceForge!

I'm pretty sure most of the advice on the 10.14.4 thread very much says to update Clover to the latest version and update your kexts! You should also be very careful to always choose the 'Boot MacOS install' option on every reboot until it has finished doing what it needs to do and until that option goes away and you're left with your standard boot partition again.
