Downgrade from 10.8.3 to 10.8.2?

I've been having absolutely nothing but trouble since upgrading to 10.8.3. My Macbook Pro now has constant graphical glitches that culminate in the machine frezzing up entirely about 3-4 times per day, with the only recovery being a hard restart. This only started happening since upgrading to 10.8.3.

I've tried resetting both the PVRAM/NVRAM, as well as the SMC, and neither worked. I tried re-installing OS X, and that did not work. I tried re-booting into Safe Mode to see if that would make a difference, but the machine will not boot into Safe Mode, as the progress bar gets stuck forever about 1/4 of the way through.

So, how can I downgrade my machine back to 10.8.2? Please advise. Thank you!

P.S. For an idea of the kind of glitches I'm talking about, please see these videos I took of the problem happening on my machine:

Safe Mode problem information.

Safe Mode – Can’t Boot Into

Running the combo updater has worked for some people.

10.8.3 Combo Update

Do you have a backup of the 10.8.2 system that you could restore from?

Without access to the full 10.8.0 or 10.8.2 installer, or a TM backup containing the previous 10.8.2 installation, you can't. If that's the case, then you're only option is to take it into an Apple repair station.

Took the machine to the Apple Store today, and they have no clue, other than the dumb advice to "Replace the logic board" (even though they are not sure the problem is caused by the logic board), or "Re-install from scratch", which would 1) Delete all of my data, and 2) Require me to restore from back-up, which would then presumably re-copy the bug back onto my system in the first place.

That does look like a hardware problem to me.

Re-installing doesn't delete data (unless you erase the partition), although you should keep a backup. Any bug is not likely to be in your data, but in the OS files. So, yes, reinstalling the OS is a sensible option.

And, I have to agree with William Lloyd, it looks more like a hardware issue, graphics section. If it's still under warranty/Apple Care, let them fix it.

Thank you for the replies. Here is some more information about what happened at the Apple Store today:

1) On my machine, we were able to make the problem happen immediately.

2) We booted a clean OS from an Apple store test external hard drive, onto my machine, and the problem did not happen.

3) We booted from my machine's HD onto another Macbook Pro (using Firewire/Target Disk Mode), and the problem did not happen.

Try the re-install and post back.

I have already tried re-installing Mac OS X (the type of OS re-install that does not delete all my data), and it did not work. That's why the guy at the Apple Store then suggested a complete Erase Re-install.

Also, FYI, I cannot boot into Safe Mode; the progress bar gets 1/4 of the way through then freezes forever.

Then, try the erase and re-install. It seems unlikely that the issue is attributed to your data.

If a regular (non-Erase) Re-install of my OS did not fix the problem, what is different about an Erase and Install that would make the outcome any different?

It's a process that removes the possibility of the influence of remnants/files from previously installed OS files.

The thought occurs to me that if you spent more time following the recommendations of people trying to help you, and less time making and posting videos for YouTube, you might have resolved your issue by now. IMHO.

Done, bye.
