Blue screen after update to 10.6.2

My macbook ''successfully updated'' 10.6.2 and that was as far as it went. Stopped at the ''aurora'' display. Disk drive made a rhythmic sound. Could not restart it. Tried and failed to re-install SL using the upgrade disk. Installed a second time and this time it took it! It is working normal again. SL has given me an unusual amount of headaches and therefore I'm going to stop ''upgrading'' until things are settled....

I also have the issue that Hans does. Failed to back up a weeks worth of work (I know) Any suggestions?

Hello to everybody.

Try this one: unplug everything from your iMac, every cable, even the power cable, mouse, keyboard, periphericals, everything, and leave the iMac like this just for few minutes (we are resetting the Power Management Unit, PMU).

Then, plug in the power, keyboard, and mouse and turn it on.

Have you tried a safe start? Restart and hold the shift key.

've had multiple problems with 10.6.2. On the phone with Apple Tech Support twice, discussed 5-8 minute blue screens on startup, frozen machine after sleep, and extreme frustration. Bottom line: 10.6.2 has wreaked havoc with my machine, and I would strongly suggest avoiding this update at all costs.

Both techs recommended reinstalling Snow Leopard from the original disk, which I did. The first time, I tried the 10.6.2 upgrade, with the same annoying problems. Then I did it again, without any upgrade, and I still got freezing and blue screens.

So the third time I reinstalled SL, I did only the 10.6.1 upgrade, and now everything is fine.

I don't think I'll do any future upgrading until at least 90 days after the release date.

I love my MacPro and other than for 10.6.2, I'm a very happy camper.

Same issue as alembee. Clean install of 10.6. Installed Xcode from disk. Changed a few preferences. Got prompt of 10.6.2 update (plus iTunes and Remote access). When updates were installed, I was given the options to "restart now" or "restart later". I chose now. It looked like I was logged out, but the computer (original MBP Core Duo) stalled at the background nebula/aurora image. I could still move the mouse. Since I enabled ssh remote login, I tested it from another computer. Sure enough, I could login to the MBP and see all the processes running (top). I executed a "sudo reboot" to remotely restart the system.

I put in the 10.6 disc (held down "c") and went to Disk Utility. Ran Verify Permissions and Verify Disk for good measure (nothing wrong). I have upgraded the RAM and HD since purchase, but I don't see how this would be an issue. Since I was able to login remotely, it was seems to be an issue with proper logout and restarting.

I have somewhat of the same problem. This morning I booted up my MacBook and it just loaded a blue screen. I installed SL about a month ago and I haven't had any problems until now. I really need someones help, I have tried multiple times to boot in safe mode but when the grey bar is loading only about a quarter of it loads and then it goes to the blue screen. I really need to hurry because I have a very important essay due tomorrow that was on my laptop. If I just reinstall SL will my computer work?

I have also been living with this very annoying problem and pretty disappointed that an update had this effect (expect this stuff with windows, but not Mac!). I keep expecting to see an update to fix this but have yet to see any sign of it. Does anyone know if Apple plans on fixing this soon?

Only Apple knows what it will do until it does it. However, don't assume that an update will fix your problem, which most likely has some other cause than the current or recent updates you have applied to your Mac.

Because there are several possible causes, it would be best for you to start a topic of your own, so that we can suggest ways to eliminate all besides the actual one, & hopefully a way to fix it without your having to wait for an update that may have no effect on the true cause.

Thanks for the reply.

It looks like my problem is related to the screen saver. I was using pictures for the screen saver and when I switched to another setting no more problem. There is another topic on this specific problem and it lists a workaround but for now I'll just use a different screen saver and see if the next update fixes the problem.
