I had Clover with unpatched OVMF which worked before but hangs after 
"AppleKeyStore starting" and before "IOAPIC: Version..." messages since 
the above patch. Maybe it's a problem in Clover and I should try a newer 
version.

It boots with your patched OVMF so now I'm using that instead. (No boot 
menu but it's faster.)

I could not test reverting because this patch does not cleanly revert on 
HEAD now but my image with Clover booted with the version before 77af8a2b9 
and hangs starting with that patch. So since OS X 10.11.6 can be booted in 
another way the subject should be this commit breaks Clover (at least the 
old version I had). I can't test with a newer Clover version at the moment 
but my problem is solved for now.

Thank you,
