Its finally here ran software update and this is now available and says:

This update is recommended for all MacBook Air computers, and addresses issues with video playback and processor core idling. Third-party software that modifies processor operating characteristics such as frequency and voltage is not supported and should be removed before installing this update.

honestly, regardless of if it works or not i am still going to CL my 1st gen mba in a few weeks for these new penryns due out any day... am REALLY hoping that apple has put these past 200+ days to good use in their engineering dept and worked out all of the kinks.

Ooh, must call father to tell him to update… he only updates when I tell him :rolleyes: He's not exactly a computer wiz.

EDIT:

Only 83KB?! I didn't know that was still possible!

Will this stop the BS one core at 100%, the other core at zero, and the computer turning into a useless $3000 doorstop until you shut it down, take a walk around the block and boot back up? :-/

No. It'll fix the whiny users that are about as intelligent as a door stop. Happy?

Its coolbook. Furthermore, it seems to be on the OS level and not the firmware level because installing 10.6 doesn't give core shutdowns even passing over 100 deg C.

Edit, I installed this patch and it seems to be keeping my CPU pretty cool even with youtube running.

I do not know if this was fixed as part of my repair by apple or if it was the download, but I just watched an entire movie in iTunes without any problems, temps hovered at 58* without any stutter or core shutdown.

I was not able to do that before and this is the first movie I watched that was over 2 hours since the repair and just installed the update tonight.

Thought I would share.

I deactivated coolbook to install this...my temps immediately shut up 10 degrees after reboot!

this happen to anyone else?
Click to expand...

Im at 71 deg C right now with 6200rpm fan. Im connected to a external monitor while running internal and booting up vista in vmware fusion. So far, the temps aren't going any more higher then with coolbook enabled for me.

Edit: oh, and im on youtube on the external screen. my cpu is at 100% both cores but no shut downs and my temps aren't going above 75 deg C. Its actually down to 69 now.

Edit 2: I believe this patch has fixed the core shutdowns. I cannot get the core to shutdown no matter what I do and I've pegged the CPU to 100% for nearly 5 minutes now.

Edit 3: Okay, apparently, the fix is just to fix the core shutdown, however, you basically run at a 0.8GHz CPU to prevent overheating. Using the MSR Tools from this link:

https://forums.macrumors.com/threads/459306/

You can test it out yourself. I'm running at 50% (0.80GHz) instead of 1.60GHz but my cores don't shutdown.

Wow.. seems sort of specific.

They even mention Coolbook. (indirectly)


perhaps I won't need that any longer :D

so basically we now have 800MHz core duo's? no performance beyond 800 MHz at all?
Click to expand...

It drops to 800MHz when you're maxing the system out and pushing it onto the brink of overheating. After I closed off youtube I was able to get 75% speed back until my temps reached low enough until i got 100% throttle back

my temps are high but no shutdowns...this update definitely addresses the core shutdown issue...job well done Apple?

The only way to test this is Logic Studio and play the tutorial file, Shiny Toy Guns - Le Disko (the 5.1 version to a sound card)
