Changed BIOS settings, but it didn't solved the problem. Now I noticed that the start-up screen (apple logo and progress bar) is gently fading into black screen. Previously it was done in a blink of an eye, and much more later (progress bar took longer to fill).

I'm thinking maybe I can replace the CLOVER folder on EFI Partition with the one on the pendrive. Do you think it may work?

You may have something else wrong. Clover setup on USB vs. Clover setup on HDD are the same regarding graphics.

Perhaps you should try a fresh install for comparison.

Also when I boot without hdmi cable in, and plug in after the screen goes black, laptop restarts and OSX says it has crashed and if I want to report this problem to Apple.

This would be expected with EFI/Clover from USB.

Or it could be caused by the fact you still have VoodooHDA installed. Perhaps VoodooHDA is the cause of your black screen issue too... No idea... this guide doesn't use VoodooHDA.kext.

FYI, my offset for the DMVT change was 0x18C

setup_var 0x18C 0x4

Whereas the HD5500 guide said to look under the Setup section, I found the settings in the SetupUtility section of the bios file.

Thanks. It corresponds with a previous report in this thread.

I've made a note in post #1.

I'm pretty sure I followed everything to a T but I can't seem to figure out why I am unable to partition the 256gb ssd drive using disk utility. The partition drop down is grated out and can't be clicked. Feel pretty stupid getting stuck at this point. Secure boot is disabled and I'm on bios v1.14. What could be the problem?

Do you have the disk itself selected? You can only partition a disk.

Hehe I wish it was as simple as that I have the disk selected and see several partition within that disk. It's just that the partition dropdown is grayed out. Could there be some kind of lock or security on the drive? I've done hackintosh installs dozens of times and this is the first time I've seen this.

Hey RehabMan,

Thanks for this fantastic guide. I have a small glitch here. I followed the steps written in "Known problems" section but still the audio is not working.

I have installed 10.10.4 following your guide.

Any thoughts.

Thanks in advance.

My apologies I missed that step. Attaching DSDT/SSDT file, IOReg and EFI/CLOVER currently in use.

Thanks for your patience.
