Most things seem to be working fine, I just can't get iCloud / Messages / Facetime to work. I've tried about every fix I could find by searching Google with no luck. From what I've read it might be something with the Machine's UUID, It is using the generated one instead of the one provided by the computer it's self. Of course, I could be totally barking up the wrong tree.
Luckily, The App Store works as it should.
What kind of bootloader do you use Chameleon ? and have you with chameleon also the filenvram module activated, maybe you can also try Clover.
