Glitches on boot

radargb · August 22, 2014

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?

First stage of boot:

Second stage of boot (just before login screen):

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

Is this fixable? (Attached)

Intel Iris 5100/i7-4558U

Thanks, i was having the same issue and the clover patch suggested partially solved it.

But for a very little time (something like less than a second) just before the progress bar start to accelerate i still see the glitched apple....

Is this fixable??

Dwors · October 23, 2014

Hi guys, I'm having this same exact issue during boot. The strange glitchy apple logos. I don't know what patching kexts is or how to go about doing it. Can someone please direct me? Thank you so much!

snoozepops · October 27, 2014

I'm sorry , but will this patch fix the graphics glitches on a chameleon installation also?

eterea · November 12, 2014

Hi.

I have the same problem, but I'm using Chamaleon or Chimera.

Is this solution only for clover?

Thank you very much.

>Federico< · November 12, 2014

For Chameleon Users:

Edit IOGraphicsFamily.kext/IOGraphicsFamily with an Hex Editor

For 2nd Stage Boot1

Find (HEX): 85C0745D48

and Replace with: 31C0745B48

For 2nd Stage Boot2

Find always in HEX: 4188C4EB03

and Replace with: 4188C4EB23

Save it.

Repair permission and cache with kext utility for example. Reboot

For Lazy people: just download the kext already edited below.

IOGraphicsFamily.kext.zip

liujianwei · November 17, 2014

EDIT: I Found this new patch which worked for me.

I am setting up a new mac build with a i3 3225 in a GA-B75N with 8GB Corsair Vengeance LP RAM, a Intel 520 240GB SSD and using build in Intel HD4000 graphics as my chassis is tiny.

Problem is like the rest of you that I have the graphic glitch on the loading bar, the progress thing right before the desktop appeared.

Can not seem to figure out to resolve it... Please help Have attached my config.plist

EDIT: Error You aren't permitted to upload this kind of file

So no config.plist

I finally solved the issue here, not a perfect solution but a heck of a lot better than before.

I have tried everything..... Finally I got the idea that maybe it has something to do with the resolution my MB supports in BIOS and yes, I was right!

Found out others have had the same idea so all I needed was my old Mavericks USB installation drive that is not using Clover, because in that I had the option to see video info when I hit spacebar during boot up.

I can apparently use 800x600 or 1280x1024 resolution and avoid see the pink flicker on the progress bar.

Added the resolution to my config.plist and heyho it boots nicely now, just a bit bigger until I reach login screen were the resolution adjusts itself back to normal.
