Hello,
I'm trying to install Yosemite on my m4600 laptop but I'm not really sure on how to do it, I've tried it following this tutorial but I got a black screen right after chimera (chameleon, stolen and rebranded) (chameleon, stolen and rebranded) booted the installer, I've tried several boot flags but no luck. Then I tried to do it with Clover; it got stuck on the Apple loading screen, it wouldn't progress. I have no idea on how to do it or fix the black screen or loading screen, can someone help please?
