Hello!

Thanks in advance for any help provided with this:

I swapped displays between two white macbooks (one was cracked). Now the macbook with the new screen can only just boot past the chime and the apple logo and then- kernel panic! - "you need to restart your computer........" big long error message OR the BSOD.

Tried safe mode, it's no better.

Booting in verbose mode i see the error "GFX0: family specific matching fails" and "display: family specific matching fails"

Is there a way to make the macbook happy with the new display?

Thanks again.

Are you sure both displays are interchangeable? If they are, the best I can suggest is to go back over your work to make sure everything is connected correctly. For step by step details go to iFixit: The free repair manual.

Display Family matching? Almost sounds like some MB's use different displays and they are not interchangeable! I sure HOPE I am wrong! :D

Thank you chscag and thank you dtravis7!

I guess the displays are not exactly, perfectly interchangeable. But I have hopes that there is some kind of hack to get around the mis-match. It's driving me crazy because it has worked- twice- but not for long. It mostly just crashes now...

BTW I used this video as a guide to the screen swap

update:

both donor and recipient macbooks are model MacBook 1,1. So the display should work.

I've learned that the mac's firmware queries the display for compatibility upon startup.

So I need to hack the firmware somehow to get past the kernel panic.

Anyone know how?

Thanks again.
