csillamfaszlama Posted March 5, 2015 Share Posted March 5, 2015 Hi guys! I have recently installed OSX Yosemite on my computer: Gigabyte Ga-z87M-d3h Nvidia Geforce Gt 630Intel Core i5 4690kSo, my problem is, at boot sometimes I get grey screens (like 1 of 3 times), and at shutdown, my computer doesnt stop. It shuts down my screen, but it seems like it hasnt shut completely down. Also, sometimes when I plug my USB sound card in (Focusrite scarlett 18i6), OSX freezes. I use chameleon bootloader. Could you help me what causes this problem? Quote Link to comment Share on other sites More sharing options...
Codinger Posted March 5, 2015 Share Posted March 5, 2015 Welcome to the Insanelymac forums , please put your specs in your signature and tell me your boot-flags. You can also try to boot with clover (Installed to EFI) happy hacking OSBeast Quote Link to comment Share on other sites More sharing options...

Codinger Posted March 11, 2015 Share Posted March 11, 2015 Chameleon is not good for UEFI boot. Use Clover instead Happy Hacking OSBeast Quote Link to comment Share on other sites More sharing options...
