After about 2 weeks of trial and error trying to get this lovely OS working on my Mac, I still have a few issues:

I can't figure out how to make f1-f12 work as standard function keys w/o holding fn.

I have to boot in Legacy mode in ReFind with apci=off in GRUB.

And most importantly, shutting down gets me as a black screen with the message "[2501.546937] reboot: System halted," with the underscore blinking underneath, from which point I have to hold down the power button. I'm guessing this might be due to booting with apci=off.

Any suggestions are appreciated!

When you ask multiple questions, you need to find one expert versed in multiple areas which becomes more unlikely the more questions you put into... well, one question! ;-) So please, split up your question into multiple questions and drop me a comment so I can answer one of your questions. – Fabby Jun 11 '15 at 22:32
  • I actually solved most of those, and reposted a question for the one I had left :-) – burningserenity Jun 11 '15 at 23:05
  • Voted to close question as all symptoms went away (see above comment) – Fabby Jun 12 '15 at 10:06

Downloaded drivers from Mactel support, now able to boot in EFI mode and shutdown works properly.
