Currently Being ModeratedAug 22, 2008 10:17 PM (in response to Dan Benninghoff)mine doesnt usually have a core shutdown but it does get super hot and starts slowing down programs. and if im on stickam and im on youtube at the same time, it freezes. hopefully this said update will fix something :PMacbook Air, Mac OS X (10.5.4), 1.6GHz 80GB
Currently Being ModeratedAug 23, 2008 12:09 AM (in response to ace101)The update resolved all my current problems with the Macbook Air. The Fan won't stuck at 6200 rpm anymore, the Macbook seems to run cooler and the Core shutdown issue seems to be resolved as well.
Thanks Apple. No need for Coolbook anymore! ... just a little too late

Currently Being ModeratedAug 23, 2008 2:03 AM (in response to Franz1234)Well after using it for a few hours it looks like a simple restart made everything as before. The Fan sticks at 6200 rpm even around 54 degrees. That's a blameMacBook Pro (early 08), Mac OS X (10.5.2), Core2Duo 2.5 GHz
Currently Being ModeratedAug 23, 2008 2:28 AM (in response to Franz1234)I installed the update since early morning. I fail to see any difference. Maybe, just maybe, the fans kick in a little later and cool down somewhat quicker. Otherwise, the same story: MBA overheats, Safari eats sometimes around 50% of CPU (windowserver is the other offender), fans blow 6200 rpm every time I try to load a more complex webpage. I cannot figure out what this update is for.MBA, Mac OS X (10.5.4)
Currently Being ModeratedAug 23, 2008 6:02 AM (in response to purcelul)Sounds like you are having SOFTWARE problems.
Time to do an Archive and Install.
Currently Being ModeratedAug 23, 2008 6:05 AM (in response to purcelul)No difference after install. This is sad. 6200 rpm after minutes of video. No core shut down (never had that issue)... just the fan, heat and choppy video playback.

Currently Being ModeratedAug 23, 2008 9:16 AM (in response to Zebra1)Nah, re-installing doesn't work. I did it twice, wiped clean and re-install. Same problem. Not sure if it is software or hardware related. Could be both. In fact, it could have been worse if I'd allowed Spotlight to index a large folder (18 GB) of PDF files. I also notice that the fans kick often when the CPU is not really hot, like 52-53 degrees Celsius. Very sloppy job, Apple.MBA, Mac OS X (10.5.4)
Currently Being ModeratedAug 23, 2008 11:06 AM (in response to Dan Benninghoff)I need to do more tests, but so far, I do not have any more core issues, when running SL(tm), that is a very heavy application, in terms of CPU and GPU.
I think now, the issue was solved, but I will do more tests later on.MBA 1.6, Mac OS X (10.5.4)
Currently Being ModeratedAug 23, 2008 11:14 AM (in response to Dan Benninghoff)Does this mean SMC update is not necessary?MacBook Air, Mac OS X (10.5.4)
Currently Being ModeratedAug 23, 2008 5:35 PM (in response to purcelul)Thanks, Apple, this seems to have solved the core shutdown issue.
Notice that there are three separate issues that should not be confused
1. Core shutdown at high CPU load. This was critical, as it essentially made the MBA useless for some tasks. This update seems to have solved it. I tried to run MPEG Streamclip for long time, and I had no core shutdown. kernel_task still did run crazy, but the computer did not become choppy.
2. High fan speed at low CPU load, such as e-mail or word processing. Not sure if the update solved that. There is no claim that it did in the update info, so maybe not. However, this is mostly a nuisance, not a critical issue like the core shutdown.
3. High fan speed and a hot computer at high CPU load, such as video. This is normal. If other programs such as simple web browsing brings the CPU load high, this is probably more a software issue in OS X than a problem with the MBA.
So, it seems Apple has solved the most critical issue with the MBA. Great. I almost regretted I bought it, but with this I'm happy again.MacBook Air 1.6/HDD, Mac OS X (10.5.4), MacBook (10.4.11) iPhone 2G Dell Windows XP
Currently Being ModeratedAug 24, 2008 4:23 AM (in response to purcelul)Like i said: You (still) have a software issue. Unfortunately, it isn't one that a reinstall will fix because loading complex pages that perhaps Safari isn't compatible with could do this to you. You are basically having Safari problems. The rest is normal when the CPU runs high at some task that never ends or taxes it greatly.
No matter how many times you reinstall you'll have this problem unless the website changes something or Safari can handle it.
Spotlight takes a while to do the first index. You gotta have patience and ket it finish. Go away and come back in a half hour.
Currently Being ModeratedAug 24, 2008 9:52 AM (in response to Zebra1)Unfortunately, I also tested this hypothesis. Spotlight simply seems to take forever to index an ebooks folder. Worse, every time I download a larger PDF file in a folder that's not excluded from the search, Spotlight lights up the fans for quite a while. It's simply annoying.
Safari eats loads of CPU cycles almost no matter what webpages I visit. It is enough that it is a graphic-intensive page and the CPU and fans fire quickly. Like now... It sure does look serious to me, so the "rest" is not normal.MBA, Mac OS X (10.5.4)
Currently Being ModeratedAug 24, 2008 11:48 AM (in response to Dan Benninghoff)Installed the update, don't have 3rd party cooling software installed. First test I did was that iChat worked, and yesterday this performed nice.
Today I was playing the whole morning streaming audio. My room temperature is warm, I wouldn't say hot, and tried running a you tube video in Firefox 126.96.36.199 and the cpu bars (Activity Monitor) went all the way up in my Dock and system was "beachbaling". After I killed Firefox the cpu usage went down and system performed back normal. The Macbook Air felt very hot on the left top side.
Still not perfect even after the update, ...

Currently Being ModeratedAug 24, 2008 12:24 PM (in response to Marc Van Olmen2)The update seems to have solved all my MBA problems. Video runs much better, the cpu stays low, and it doesn't overheat. It seem to be throttling the CPU much better now. I have the Activity Monitor running in the dock at all times, and I can see that the CPU load is staying lower - even for the Apple Quicktime videos on the Apple Home Site. Looking at these videos used to drive the CPU to 100% eventually resulting in the core shutdown problem. It's too bad it took this long to get the fix - I got my MBA in the first release - so have lived with this for quite a while.iMac Aluminum 2.8 24Inch and MBA 1.6 HD, Mac OS X (10.5.4)
