Dec 19, 2010 5:08 PM in response to yogidigby yogidig,I still using 10.6.5, I have been using my Computer with a wired mouse and i got a couple of crashes. It seems to me that I have to do with the GPU usage (as someone mentioned before) .. My computer gets really hot and it started to failed when the CPU temp goes above 54ËšC ... I hope it gets fixed in 10.6.6 or if someone knows of any mod that can be use to keep the computer cool, besides SMCfancontrol
Best regards,
PS: English is not my first language, so my apologies for any mistake. -
Dec 19, 2010 5:18 PM in response to DazzaGby Mark Quarmby,I have been using a Bluetooth mouse (magic mouse) and it has worked perfectly. Since I last reinstalled my OS and removed Safari 5.03, going back to 5.02 about three weeks ago, I have had no problems until a week ago. The computer had gone to sleep and when I woke it, the screen saver appeared but was frozen. I had to turn the power off and let the computer cool down. When I restarted it, it did restart (which it hadn't always done in the past since upgrading to SL) and I found that the menu app "Mail Unread Menu app" was using up 97% CPU. I force quitted it and removed it from my start-up items and all has been well since. I don't know if this will help others.
As I only installed SL a few weeks ago, I went straight from 10.5.8 to 10.6.5 so didn't experience the problems in between. -

Dec 24, 2010 1:44 PM in response to DazzaGby Simon Baker,Well, I've been suffering this since 10.6.3 and tried everything…or so I thought. The imac was stable with SMCFanControl at 1600 rpm on the ODD and 1400 or so on the CPU. However, after seeing a similar thread on a macbook pro, 3 days ago I switched to a different account after placing the SMCFanControl back to default (1000/1200 rpm etc) on the previous account.
Its been 3 days 14 hours and 16 minutes now… Just left with a seemingly reliable, responsive, no-surprises iMac on 10.6.5. Makes no sense to me. Even my Wife can't crash/freeze it (always thought to sell her off as a software reliability checker).
Will let you know if this is just an illusion caused by a passing OSX fairy at this time of year, or the fact that it is -2ËšC outside.
…but if you haven't tried this very simple "test" then you nothing to be lost? Anyone else tried it?
(if it makes 10 days, I may have to apologise to Apple…)
Hoping the fairy sprinkles something good on your machine

Dec 27, 2010 9:10 AM in response to Simon Bakerby SeSam,3 days is nothing. Mine sometimes runs for 5-7 days without a freeze then locks up (usually when most needed and I have the most unsaved data open).
I don't really think 10.6.6 would do anything, it's just to introduce the App Store. -
Dec 28, 2010 1:24 PM in response to SeSamby Simon Baker,Mine is still running fine after over a week, no freezes - only shutdown and restarted once when I needed the table for the Christmas guests!
Have you tried what I suggested? That is set up a new account and log into that for all uses? I cannot fathom why this should work, but MacBooks appear to have the same issue and fix. Its a very simple thing to do - the only challenge is transferring files over between accounts.
Maybe it is a corrupt file in the user library somewhere? (so don't copy those over, just the data files?) The SMCfancontrol fix I used for 6 months or so to get around the regular freezes makes this a quite bizarre issue.
I will let you all know if this thing ever freezes again, but I really (dare I say this…)am beginning to think I am out of the woods now.

Dec 28, 2010 1:32 PM in response to Simon Bakerby Tazthed,Okay, thanks for info.
Yes, please let us know when it freezes again.
And if you haven't done it yet, then you can report your old "freezes" to Apple in hopes of they will fix the problem in an update in the future:

Dec 28, 2010 4:14 PM in response to Simon Bakerby nekosaur,Followed your advice on this one - created a completely new user, set-up MobileMe for syncing, transferred only the iPhoto library and opened iPhoto. The iMac froze as soon as I started scrolling through photos and has continued to become more and more unstable. All in all, it took about 15 minutes of use in the new user before the machine froze
Was hoping this would work, but it didn't for me. -
Dec 30, 2010 6:44 AM in response to DazzaGby 79tata,Hi all,
I have experienced the same problem, and read entire thread. I have a mid 2007 iMac Aluminum 2ghz with 3gb non-Apple Ram. The machine has been flawless for more than 3 years. I upgraded from 10.5.6 to 10.6.5 and it was ALL DOWNHILL from there. Almost immediately I started to get black screen in the middle of doing something. Almost like I hit "Sleep" but didn't. It would also freeze with the display looking normal, but mouse an keyboard were unresponsive. Other times the screen would be overcome with noise artifacts, and again the mouse and keyboard unresponsive.
I read some posts about a bluetooth mouse being culprit, in which I have. So I turned off bluetooth and ran with a USB mouse and that did not make the cure.
I went back to SL DVD and installed 10.6 again and did not do ANY SL updates and it has been running flawless again. Whether it be a hardware issue coming out in 10.6.5 or whether the OS itself, I recommend not going to 10.6.5 -

High fan, then freeze.
This is a new 20" iMac "11,2" running 10.6.5, with bluetooth keyboard and mouse.
Reinstalled 10.6.5 from a combo updater, ran fine for about two weeks, now two freezes today, one about an hour after rebooting.
I'm going to try with a wired mouse . . . -
Jan 5, 2011 3:38 AM in response to DazzaGby spl70mk,I have a late 2008 24" imac which recently has started getting very hot at the top left of unit on back, once heat increases to a point the screen then either displays a blank blue ish or grey lined screen.
I then have to disconnect power lead from back let machine cool before switching on.
Any help would be greatly appreciated. i am running 10.6.5 -

Jan 6, 2011 9:24 AM in response to Tazthedby TravelCommons,My MacBook Air has been spinning for 3 hours on the 10.6.6 upgrade -
Jan 6, 2011 9:27 AM in response to Tazthedby nekosaur,• Restarted iMac
• Repaired permissions
• Restarted again
• Downloaded Combo 10.6.6 update (1.06GB)
• Installed & Rebooted
• Repaired permissions again, restarted again
Stable for 17 minutes until I was scrolling across the dock - hard freeze. Mouse moves, screen not responsive. Hard power down.
Sigh..... so sick of this. 10.6.7? -
