Here is where i get that error:
Code:
Error: 0 substitutions made.
Any thoughts?
Thanks

Nico
It just means that the script didn't find anything to substitute. It can happen if the file was already patched or if it's not the correct file ( i.e the wrong driver version ). It only works for the drivers published by nvidia at the beginning of the month.

Were you able to successfully log in before you installed nvidia's kexts? Can you boot in safe mode? Are there any relevant messages in your logs?
Yes I was able to login successfully before installing nvidia kexts. I am able to boot in safe mode, but I don't see anything relevant in the system logs. This is a log in normal mode (non-safe): http://pastebin.com/chDVg0FG

I forgot to mention this but /Library/Logs/DiagnosticReports would also be a relevant place to look for logs. In fact without the fix applied the infamous "login loop" is caused by loginwindow.app crashing and its crash reports get written to that place. Maybe your problem is caused by something similar.

Here's a list of md5 checksums if you want to make absolutely sure that the proper files are in place.

A lot of these are identical because it's the same file renamed/symlinked. They probably originally all stem from the same framework/library that Apple saw fit to split up and dispatch during the course of the years.

On a final note if you want to revert the fix simply boot in safe mode and reinstall the 10.8.2 update it will erase any modification made by it, that's the slow and easy way.
Or restore all the files saved in step 1 of the fix to their respective locations, that's the faster and slightly more complicated way.

Kext's checksums match, but the framework's ones are all wrong. I just applied your guide stopping at the ### marks and using only the first zip file, should I have gone further and followed the second part of the guide too?
Under /Library/Logs/DiagnosticReports I only have entries starting with mdworker, one of them is here: http://pastebin.com/vCVFYMWf
I would like to stick with your modifications, since they will allow me to have a fully functional system, with both video acceleration and sleep support.
Thanks ;)

Hi all,

Im on 10.8.1 using latest NVidia released driver, and I'm getting random screen freezes, dmesg just shows:

NVDA(OpenGL): Channel timeout!
NVDA(OpenGL): Channel timeout!
NVDA(OpenGL): Channel timeout!

Is this supposed to happen?
I thought Nvidia drivers had fixed all issues.

nope, it is well known that does random freezes exist. Don't know why nVidia don't fix this as well.

10.8.2 has been a lot more successful for my Gigabyte 550ti with vczilla's instructions (no freezes), have you tried it?

I'll give 10.8.2 a try, but I don't think it should be different from 10.8.1 as the solution is to use the same NVidia Drivers and Frame works.
In fact, I'm having issues with this card since I bought it (10.7.0), random freezes, screen artifacts, I'm very tired, will never buy other nvidia card again. I don't know if nvidia goes well on windows, since I don't use windows for more than 6 years but regarding my experience with this 550Ti I think nvidia is a real bad choice.
I'm seriously thinking on buy an ATI Radeon R6870, I've read here in this forum that it is very stable and fast.
I use my computer to work, and it's a real pain in the 'neck' to have random freezes and reboot several times a day, very annoying.

Thanks for the help, I was hoping this new Nvidia driver would fix all my issues, but now I don't think nvidia will ever fix this.
I'll let you how it goes with 10.8.2
Thanks

10.8.2 is better but they still occur. I believe it is a memory leak in the GPU usage - I can monitor mine using an application I run 24x7 (BOINC from BERKLEY) and it uses Open CL for GPU*processes. When I boot it reports 905M free on my GT 550M; after overnight running, screen saver comes in once and then the display sleeps for 8 hours, that number drops to 840M or so. This continues throughout the day until the memory drops so low I'll get messages (internal to BOINC) about how the process is waiting for GPU memory. If I do not reboot, it will eventually freeze trying to come out of a screen saver or back from display sleep with the Channel Timeout message.

My son's MacBookPro has a similar issue although his reboots after the error, not a freeze; my wife's MacBookPro freezes. My daughter's MacBook has not failed, as far as I know, and she NEVER reboots. My MacMini Server has freezes but they are really rare.

The point is these issues will eventually be addressed and are not unique to the 550TI; turning off the cutesy stuff like background changes will reduce the affect and rebooting once a day may 'eliminate' it for most of us altogether.

vczilla's fix works; I did it wrong before he posted his fix and had issues so if some of you are having issues, just clean it up and try again; ignore the error messages on commands until the CHOWN command - if CHOWN doesn't find something then you did something wrong.

Pictures attached.
