Snow Leopard freezes constantly

Hi
Lot's of people seem to have similar problems with Snow Leopard. I'm feeling a fool for upgrading to Snow Leopard so quickly, but Leopard worked from first installation with no problems and the Mac had been so stable for so long I just thought maybe they'd cracked it!

I'm hoping someone might have a suggestion to solve a pretty painful problem with the Mac. I installed Snow Leopard, but it has started freezing as soon as the Mac screensaver / disk sleep / display sleep happens.

In line with other suggestions I've updated the printer driver (that did solve one problem) and I've checked the permissions and run the repair programme (one permission was repaired). I've also installed the 10.6.1 software update. Notwithstanding this it still freezes and the report says that it is a kernel panic.

These are problems I've never had before with the Mac running Leopard. It never froze, never crashed. To be honest, I've never had an error report before (maybe I've been very lucky?) All of the problems seem directly related to the installation of Snow Leopard.

I am contemplating reinstalling Snow Leopard, but will that make a difference?

It'd be great if anyone has any suggestions.

Thanks

Ok, so maybe my issue isn't SL directly. Cos I downgraded back to 10.5.8 last night and the issue is still present, had 2 kernel panics in the last 15 minutes. Here's the log that was sent to apple on reboot:

I've been using firefox for the last 2 days or so.. and no freezes!! And I did disable plugins in safari and also no freezes.. although I haven't tested it too much to be sure... I'm pretty sure it's the flash plugin when working on safari.. (also one page seems to cause problems under firefox but it gives me the option to stop the script)

Please Update!

I finally resolved the problem today.

What I did was open the following folder:

Macintosh HD/Library/Internet Plug-Ins

Next, I created the same folder on my desktop.

Next, I moved every plug-in to the temporary desktop folder

I opened Safari, browsed to YouTube.com, navigated throughout the site, attempted to watch a video, closed Safari

I then moved one plug-in to the folder and repeated the Safari test.

After each test, I moved that plug-in back to the temporary folder until I had gone through every plug-in, one at a time.

Once finished, I moved all of the plug-ins back where they belong and Safari works normal again.

"I'm prompted to stop you there, sorry. "

Perhaps you can use your authority as a Developer and give us your detailed steps to get SL running with no problems.

That will help all those considering downgrading.

I am a long time user myself and I have always reformatted and installed fresh. Its tiresome but Its the most stable to my experience.

Due to time constraints, I skipped it this time and iTunes freezes during song playback.

I am going to reformat and install. Is that what you suggest?

Sep 24, 2009 7:05 PM in response to Fivehatters

I am having the same issue.

Any app, any game, anything I am doing, it will randomly freeze.

Then you wait a few seconds - minute and it unfreezes.

This is a HUGE glictch!

As I just got a new MBP w/ the snow leopard discs (and my old MBP Leopard discs wont work on this machine) I cant downgrade.

Do we know if this is getting looked into?

I’m having the same sort of issues. I installed SL on top of 10.5.8 and as others I have been getting all the freezes and beach balls. What’s made it really bad is I’m having rough time trying to get back to 10.5.8. First thing Apple Support suggested is a fresh install of SL, that didn’t work. Then trying to go back to 10.5.8 my system was freezing during the Time Machine process. Apple suggested I reformat the disc as apposed to just erasing it. No difference. It seems during any long process, if the screen goes to sleep, it causes the system to freeze, even if it I’m booted off the CD doing a restore from back up! So I’m now trying on a brand new drive after installing a fresh version of 10.5.8, installing all the updates before I try to restore.

Honestly I’ve been a Mac user for years and I can’t recall such a mess in recent history. I’m not a coder or developer, but I’m not a new user either. I’ve done my share of complicated procedures over the years and this is one for the books. It’s almost as if SL writes something to the firm ware or somewhere that even if you erase or reformat the drive some bit of SL remains to reek havoc on the system. Perhaps that’s crazy but it sure seems like it. It’s almost like a deliberate attack, like a virus or something. Anyway I’ve just started the restore process for the third time, it only has two hours remaining. After reading the other posts I’ve turned off the screen saver. So fare the screen hasn’t gone to sleep so perhaps the preferences I reset are holding. I hope it works, if it hangs again I’ll forget TM and do it manually. Reinstall each app and copy over each and very file ☹

All I can say is thank goodness for my Mac Book. I also have to say, I really appreciate this forum. You’d never know so many are having the same or similar issues when speaking to support. At least knowing its an SL issue eliminates wondering if its hardware which is what I was starting to think.

I’m sure eventually Mac will fix this. In the past I always waited before upgrading. I will wait longer before upgrading next time.

Well if it was me I'd call apple and ask for a Leopard 10.5 disc. They are sending me one free of charge because of all the hassle I've gone through because of SL. They ended up after trying everything they could think of suggesting I go back to 10.5.0. But both Apple and I thought perhaps my disc might be faulty causing the freeze during reinstall of Leopard. Not so you can see by the other posts. Plus my disc has finally worked to at least get back 10.5.8. What seems to help for me so fare is turning off the screen saver. I've only got 45 minutes left for the Time Machine restore to finish. So fare the screen hasn't gone to sleep so no freeze. I'm hoping after the restore process all will be back to normal. This is really very unMac. I've been a very happy Mac user since the eighties. Never experienced anything like it before. The only question I can't answer for you is can a new Mac Book install the older system? If not I'd take it back to an Apple Store or something. Anyway as soon as I know if my restore works I'll post again.
