Sudden, random freeze after 10.5.7 update

I have a call into Apple Support to see what they suggest. Time Machine seems to be unable to rollback to 10.5.6.

+1 freezing. The following thread describes a similar problem when sleeping the computer:

Several posts suggest deleting specific preference files in /Library/Preferences/SystemConfiguration that were newer than April 1. To those experiencing freezes, do you have BlueTooth enabled? A few major updates in the past have not played nicely with the BlueTooth wireless mouse/keyboard drivers.

Me too, everyday, usually while watching an online video (youtube hulu etc) it freezes. This never happened once before the update. Can't force quit can't do anything but hold the power button until it shuts off. I do not want to do this everyday, please fix this asap.

I repaired disk permissions via the Disk Utility on the main, boot drive, then rebooted the computer. So far so good after 2 days.

If you have a 10.5.6 install disk, best bet is to run it, and select the Archive and Install option. It basically paves over 10.5.7 with few niggles after. This came with the bundle of iLife/iWork/Leopard.

Good luck.

I tracked my instability issues to the WIFI adapter. Disabling WIFI eliminated the random crashing.

Weird. I only use WiFi on my MacBook at home and have not had any problems after the 10.5.7 update. My MacBook Pro at work, which uses mostly wired Ethernet, has been freezing. I spoke too soon yesterday...I repaired disk permissions and had a freeze late in the afternoon. Assuming the problem is network related, I have now tried deleting the pref files, according to:

<http://discussions.apple.com/thread.jspa?threadID=2005687&start=120&tstart=0>

which essentially reactivates various network components. You can also try reactivating the network components (through the gear symbol) in network preferences.

Created a new user account last night, have been up for 12 plus hours with the old user account the machine would freeze in 3 to 5 hours. Hope this helps. Now how do you bring over important files from the old user without bringing over the file that caused the freeze problem?

yeah - exactly the same here too. At least once a day. I though it might only be while running Safari 4 Beta but I think it's been happening with Firefox too now I've stopped using Safari, I've not updated the two MacBooks here until I work out what is going on but I'm really, really annoyed. Never had problems before this

I am having similar problems with my iMac. I thought my hard drive was failing because the computer seemed to freeze at first during IO operations. Did 10.5.7 include an EFI update? My hard drive randomly hangs even in target disk mode. And sometimes my computer can't even find the boot disk and I get the question mark folder.

But then after refusing to even boot for a while everything goes back to normal. The S.M.A.R.T. status on my drive--viewed with several different tools, not just Disk Utility--says everything with my disk is completely fine which is why I wonder if it's an EFI problem.

I did a clean reinstall and even zeroed the disk to eliminate any bad block problems and the problem persists. Though I did update to 10.5.7 again. I am going to try reinstalling again and not updating to see if that fixes things.

Maybe my problem is separate from others in this thread as they seem to go a little beyond. But the crux of the problem is the same spinning beachball at completely random times, and only beginning after updating to 10.5.7. I have not had a single kernel panic.

I spoke with Apple support and they did not seem to be aware of the problem. I pointed to this thread. I then reverted back to 10.5.6 and I have not had the problem since. I will wait to go to 10.5.7 until they have a fix even though I hate to operate with the vulnerabilities. I can't have the constant freezes. I have updated my wife's iMac and her Powerbook and so far they have not exhibited the same problem. She has a 20" iMac and I have the 24" iMac. I have a Macbook Air but have been fearful of upgrading because I don't have a time machine backup to restore to with it.

Unlike the problems already listed in this thread my iCal is completely greyed out and all dates and info are gone! Everything else seems fine... fingers crossed!

I've been having the same problem. I unhooked my drives I use for backup - firewire - and that seems to help - last night was watching hulu and when Time machine fired up the screen froze but the sound kept playing on. The freeze happens when either of my 2 Firewire drives are plugged in. Force rebooted and the screen saver froze. The other night I did a huge transfer of data from one firewire drive to another 550+ gigs and the screen froze but the transfer ran all night successfully - unplugged my drives and it seems to working now but what about backups - happened since 10.5.7 - seems to affect spaces and expose which I've had to turn off - would freeze in spaces showing all desktops. Drag.

I am in this random freeze boat also, mostly it is just really really annoying. Luckily I do not have any pressing work to be done right now.

I spent about 30 minutes at the Apple Store today. After replicating the lock-up issue about three times, the only suggestion was to reinstall the OS, then re-update.

Oddly enough, they weren't running an updated image on their machines, so they had not experienced any of the update bugs.
