Q: 2011 MacBook Pro and Discrete Graphics Card

I used "Kext Wizard" to get my kext back installed correctly and here is the updated display profile for me ..

Also I will note that that fixed my applications crashing issues as well as finder and console crash issues.

and how do you use this?

OK you two  have a 17" MacBook Early or Late 2011. But is seams not to be the same problem as we have, because you are still running on the AMD (ATI) chip.

Compared to this HD 6750 has no Display:

Here you see the Internal GPU is used:

@odarell if you are having problems with finder crashing, or get an error when you move your kext from the temp folder bak to the extensions folder then Download kext wizard @ http://www.insanelymac.com/forum/topic/253395-kext-wizard-easy-to-use-kext-insta ller-and-more/

Click on "install" then select the kext from the temp folder, and install them.

Can you check your Logs as I discribe it here:

The GPU Hang State = 0x00000000' is interesting.

I don't know where the temp.folder is or what next files I should be targeting..

I forced mine in to 32bit mode on startup, it's the only way I can get it to run. Check out my screenshots from page 81 ... it seems to be the same problem in nature. Double screens / glitches / hard freezes.

Yeah, I saw that, thanks ... Here is my log using the "gpu" filter on system.log ... no hang state found.

That would be only because it's highlighted..trust me we have the same issue as everyone else

That's the fallback driver kicking in.

By removing *all* drivers containing the string "AMD" you've also removed the one supporting the integrated (Intel) GPU. So Mavericks booted using a fallback "safe" driver.

Despite what gfxCardStatus says in this state, you *are* running on the integrated graphics, just without full QE acceleration and with a lot of features missing (hence the internal screen wrongly reported as an external screen).

This is NOT a solution.

"applepower", please stop spreading useless information.

Hello again,

 

after moving the driver files around I got an extremely weird state. My MacBook is now booting, but shows this: stuff:

No external display is connected.

@ SpaceBacon

search also through your older Logs until you find the GPU Hang State = 0x00000000 ('system.log.1.gz' or the 'system.log.2.gz'…)

Without this it is clearly something else.

Your Log shows that there are not all needed extensions are installed. Can list me what is still in the _temp folder and what is in your Extensions folder?

-----------------------------

By the way, if read the "Fix" carefully, you will learn also how to undo it:

This procedure is disabling the 'AMD Radeon HD 6750M' permanently. You can undo this by replacing step 6 and 7 with these steps:

6. Type mv _temp/AMD*.* and ENTER

And in your case maybe also mv _temp/ATI*.*

I have no idea how to search for those logs u indicated. This has become a nightmare. Anybody know where to find the temp.files? Also that command to move the temp.files back doesn't work...probably would be a good idea to remove your post.due to.the problems it will cause..

Sorry, you are absolutely wrong!! The internal GPU does not relay on any AMD*.kext…

Think first… The internal GPU is made by Intel not by AMD who makes the AMD GPU which used to be ATI before it was acquired by AMD!!

You just have to read the post clearly it is all writen there!!

The _temp folder is in /System/Library/Extensions/_temp

@odarellmc open up "console" in your utilities folder, and search the system.log for keyword "gpu"

The temp folder will be in your system/library/extensions folder only if you created it while in single user mode using the "fix" then moved the ati files into it by using the wild card ati*.* ... the *.* would grab any file that starts with ati and mv would move it into the _temp folder.

You can download the kext wizard I sent you a link to and use it to install the kext back to the extensions folder. You cansimply drag the .plugin files back from _temp to the main extensions folder and you are back to square 1.

mv _temp/ATI*.* did not work for me either.
