[shicechi]

For those El Capitan public beta testers out there, this fix no longer works.

In order to get it fixed, you need to patch the IOGraphicsFamily:

That's great thanks!

Being picky but is there a way to fix the brief blank screen?
The transition goes Progress Bar-->Blank Screen-->Progress Bar-->Desktop

Many thanks!

I've had this issue ever since I build my system!
Tried a lot of things but nothing worked.

Gave up already, but whilst upgrading to 10.10.4 I started a new search to fix the issue and found this!!

The solution in the first post, copied below, fixed the problem for me.

THANKS!!

# Run the following commands in order to patch IOGraphicsFamily to resolve bootup graphics glitches
sudo perl -i.bak -pe 's|\x41\x88\xC4\xEB\x11|\x41\x88\xC4\xEB\x31|sg' /System/Library/Extensions/IOGraphicsFamily.kext/IOGraphicsFamily
sudo touch /System/Library/Extensions

Note that this patch seems to also work for 10.10.x. (Note: Tested only 10.10.5)

Unfortunately, nothing of this works for El Capitan...

"black boot" problem is unrelated to this thread... off-topic.

Post a separate thread.
