I took the MBP to my local Apple store that afternoon, and they replaced the HD on the spot (very surprised, and very pleased w/ the service — thanks to genius Gary). Though I cloned my entire system back in hopes it was entirely hardware, I woke the unit this morning & got a kernel panic. Fortunately, this time it did not cause disk errors as others have in the past — so some progress was made with a new drive.

I have one more sneaking hunch as to the culprit, and will know by tomorrow morning. If it’s not fixed when I wake the machine from sleep then, I plan to clone again, wipe the HD, install fresh and then move work over, but start with fresh installs of all apps & such.

A major pain, but I think I’m close to having it solved (I hope). More to follow…

I guess I'll be adding "move the Preferences folder" to my short list of troubleshooting steps.</p> Thanks for letting us know how you fixed it!

After 3 days of a clean set of user prefs, not a single spontaneous logout on wake. The Apple Genius didn’t even think of that as a fix — maybe he thought I’d been so thorough in everything else, I must have trashed my prefs too. I dunno…

At any rate, as a reminder to all — if you’re having funky issues try moving the contents of your user prefs folder aside & creating them all new.

I am now rejoicing…

  1. Verify with Disk Utility. If it finds a problem, repair it and rejoice.
  2. Run Yasu with everything checked. If that solves the problem, rejoice.
  3. Create a new admin account. If the problem does not exist under the new account, start fresh or move everything over piece by piece until you find what caused the problem.
  4. Re-format and restore from a backup. If that solves the problem, rejoice.
  5. Re-format and re-install OS X. If the problem does not exist, start fresh or move everything over piece by piece until you find what caused the problem.

Believe it or not, if you’re short on time, I recommend proceeding directly to step 5. It works every time, unless it’s actually a hardware issue.
