robrecord Level 1 Level 1
I am having random freezes like the authors of many recent topics on this forum. From the number of 'views' on their threads, it seems that many other users have the same problem.

These are not like any other freezes I have ever had - usually when the beach ball shows, it still allows me to show the dock, move windows etc... but these freezes bring everything to a halt.

Since this problem first started for me the say I upgraded, and seems to be the same (from what I can tell) for other users who reported this, does anyone know if there is something about snow leopard that uses the hardware differently? So that whereas under leopard (32-bit) there may not have been a fault, but on switching to 10.6 a problem could reveal itself?

Mac Pro 1,1 2007, 2x 2.66 GHz Dual-Core, Mac OS X (10.6), 4 x 1Gb Apple RAM, 1x 500Gb WD Caviar, 2x Optiarc Superdrive, GeForce 7300 256Mb, Dual monitors

Have any of you tried the following? That's what I would do.Try using Disk Utility to do a Disk Repair, as shown in this link, while booted up on your install disk. You could have some directory corruption. Let us know what errors Disk Utility reports and if DU was able to repair them.Then Repair Permissions. DALE

Ok there are lots of item to check for leftovers that could be causing problems.Run SIMBL uninstaller included in the 0.9.6b build.Then Check these locations for stuff not properly removed and that only 64bit SL compatible versions of the software found in these locations are installed:/Library/Application Support/SIMBL (This Needs to Be removed)~/Library/Application Support/SIMBL (This Needs to be Removed from your home directory)/Library/Bundles//Library/Contextual Menu Items//Library/InputManagers//Library/Internet Plug-Ins//Library/LaunchAgents/ (Remove SIMBL if its there)/Library/LaunchDaemons//Library/PreferencePanes//Library/QuickLook//Library/ScriptingAdditions/Library/StartupItems//Library/To reinstall SIMBL run the installer for .0.9.6b only. and check that the permissions on the /Library/LaunchAgents/ folder are "755" or "drwxr-xr-x"

    I keep a close eye on my RAM usage so I don't think it's due to running out of memory. I know what that looks/feels like, and this is not the same.

    Usually this happens when starting or activating an application from what I remember.

    I will report back here with more details if I discover anything else significant.

    I am having the same problem. I especially experience it when working on Safari, Firefox, or Word. If anyone has an answer this, please let me know. thanks

    I had a similar problem: I replaced the Western Digital Green disk drive with a Seagate and the problem disappeared. The WD was just an interim solution anyway -- but while the "green" drives are fine for backup they don't make good system drives.

    You may have a similar issue or a failing disk drive.

    I am having this same issue, and it's very frustrating.

    It's happened while on Safari, also using iTunes and Toast.

    Periodically, everything will freeze and the spinning wheel comes on the screen. It typically lasts about 30 seconds. There is nothing particular that sets this off. If I leave iTunes on playing music, the music will stop until it comes back on.

    This is problematic for me because i use my mac for DJing and i have a gig next week. I really need to get this fixed, else i won't be able to use this machine because there will be gaps in the music.

    Any help would be greatly appreciated.

    I notice that the lockups seem to be happening less frequently. I didn't had one yesterday and haven't today, so far.

    I believe the free space on my drive at the time of install was probably highly fragmented. If Snow Leopard installed onto that free space, it could be that the access times for certain system files have been distended by that fragmentation. Just a theory.

    I've been having the exact problem since installing 10.6. I'm going to try the disk utility fix... Stupid thing is acting like windoze...
  • gulfsidebo Level 1 Level 1
    I had the same problem after 2nd boot up (after upgrade), but after the 3rd boot up and since, there's been no hold ups at all.
  • N.Downing Level 1 Level 1
    Ok, after rebooting to disk utilities off the snow leopard disk I tried repairing the drive- no problems, did the repair permissions, found one minor thing and it fixed it. That was yesterday, today I had it freeze up 3 times just like before, same symptoms: Spinning wheel, no response, after 30 seconds it goes away.

    I hope there's a fix for this because I really can't have this happening in the middle of a presentation or something. "Oh wait, while I make up 30 seconds of stuff to say while my Mac that never crashes stops being stupid..."
  • Tomosaki Level 1 Level 1
    I seem to be having the same problem, even did a fresh install of Snow Leopard and seem to have vlc, safari, firefox, and word freeze for small moments (30 seconds at a time) I also noticed that my internet connection seems to drop to almost zero for my downloads during these moments.
  • Senseless Level 1 Level 1
    I am having all the same issues as above. Clean install does not fix it or disk utility repairs..............Happens alot during safari, word, switching between tasks too. A force quit does not work.........everytime it happens I have to do a hard reset pressing the power button down to re-boot. Not sure what is casuing it, I can tell you it happens alot surfing the internet.
  • maximee Level 1 Level 1
    Same thing here. Called apple 3 times already checked RAM ok checked disk and fixed permissions and last moved system configuration results no success until now I'm gonna call later this week...
  • BStaack Level 1 Level 1
    I have all the same problems.
    I have not yet tried to reinstall SL but i sounds like it is a general SL-Problem.
    Do you think there will be an update in the next days ?
  • Dale Weisshaar Level 6 Level 6

    Update 10.6.1 is available now. Hope it helps! I would Repair Permissions before and after the update.
