Ive menaged to make almost fully working Yosemite on my laptop, but one thing annyoing me so far.

 

Im having weird screen glitches on boot.

There is proper white apple logo with progress bar, and then it gets glitchy just a moment before login screen. After that everything is fine.

Realised that problem doesnt occur when im booting with external monitor plugged in.

 

Anyone having this issue? Or maybe some clues how to fix it?

I have it almost working with "Second Stage 2" Cover patch, but there is just a small loader glitch:

 

Is this fixable? (Attached)
