MACBOOK PRO & SNOW LEOPARD - OVERHEATING

do you think this is an adobe issue or a apple/safari issue have you noticed this happening with any other browsers? to be honest i havent noticed but i run safari along side firefox and chrome alot of the time so i cant really say 100%. It does see to be this one process that hogs resources and start the death spiral though. :/

Just switching safari to 32bit didn't help, but it seems that switching to the 32bit Kernel as well does the trick for me until Apple finds a cure.

Here's how to do it:
http://support.apple.com/kb/HT3773

I think it's pretty much Flash related, not browser dependent. I used only Firefox in the past (Leopard and before) and some videos always caused an high CPU usage. But today, for example, my CPU temp is stuck at 55 C doing pretty much nothing (I'm just messing up with the Terminal trying to block an IP address in the router. But Safari is open).

Anyway, if you wanna see your Mac heating on idle just go to http://speedtest.net. Even not running it nor selecting it's tab and doing something else than browsing the temp raises of 10-15 C. I wonder if this has anything to do at an HW level with the Intel Dual Core 2 Duo "switching" into 64 bits...

Well I for one am going back to nice cool Leopard until I read on this post "Yay, they fixed it!! My computer is running at the same temperature range as it was under Leopard..."

Ok, you've heard it from me...I was on the brink of nuking the whole thing and going back to Leopard. My issues were with overclocking CPU whenever iCal and Mail were opened at the same time. I looked in console, and it was filled with error messages about "not finding tasks." It just couldn't reconcile all my to dos between the two programs. Here's what I did. I deleted every to do that was completed and in iCal preferenced checked "delete to dos 10 days after they have been completed." I also removed a 3rd party antivirus program, and installed the 10.6.2 update. It took several minutes for the MBP to clean out all my old tasks/to dos. I restarted the computer, and it was a miracle. It runs at 102 degrees unless I'm running heavily intensive CPU programs at the same time (Photoshop, Lightroom) Now I don't fry my thighs and it's been behaving (really) for over 5 days with no issues at all! Hope this helps someone out there who's ready to jump off a bridge.....

First sorry for the spelling I am dislex.......

I did the same but had to re-do it becous one of the thermeal senceros got broke and the fans will run full speed or (somewhere between 4000 and 6000RPM).

When you strip the MBP (first gen) you will notice (I hope) 3 parts that are connected to the logic board by VERY small wires one is the RealTime Clock/SMC battery under the DVD/CD drive the other two are thermail sencors on on the Heatpipe/heatsink and one under the rightside fan(this one was the problem for me as the connector is not visable until you lift the logic board and if that slips then the is a good chance of brocken wires that can't be mended by home soldering. I got a replace ment from a e-bay persion that is now working.

I hope this gives you some idears.

Sorry for the spelling I am dislex....

I have a Old style MBP 1.8 Core Duo that some times Webserfing viewing streemed video the heat build up very quickley to 90c and hier. It seem that doing this makes the meachin run at the highest speed of 1.8Ghz

I have just seen one of the posts about running without the battery and yes it dous throttle the CPU and GPU 1.5 instd of 1.8 witch also has the afect of helping to keep the laptop cool. For some this throttling of CPU and GPU is not what thay want but for me it WORKED!!! (I can still watch streeming VIDEO and DVD's without lose of quoity or smothness as well as editing my photo's using Aperture witch is good) BUT!!! it's riskey becous the MS-PowerSupply can easley get disconected cousing data lose and cruption not good.

Do any one know how to throttle the CPU+GPU with out removing the Battery.

I now just force quit the Webkit Plugin Host in Activity Monitor and the temps/fans decrease.

Is this a correct action to lower temps and fans?

Thank you.

To be honest this is the WORST thing you could do. I wonder how Safari didn't crash. Nope, avoid it all.

sorry but this is the BEST thing you can do. The webkit service is seperate from safari they are independent for a reason...to stop safari from crashing when flash crashes.

Don't spread bad information!

edit: to re-enable after you have quit all you have to do is click inside the flash object on the website (e.g the video box in youtube) where there should be a little blue(?) lego/plugin icon.

Well, I may be wrong then. I understood it was an interface for 32 bit plugins, like Flash, in Safari 64 bits. But as you saw it gets restarted any time it's needed. I did a test myself (bizarre enough it did not appear in the Activity Monitor!! I had to kill it with "killall -9 WebKitPluginHost" from the terminal), I killed it and it reappeared as soon as I loaded a new video.

Thus it is a no solution anyway.

PS: about that crashing thing. Everytime something crashed in Safari the whole browser crashed. So I believe that statement from Apple is a "little bit" over the top. 😉

Same problem... 10.6.2 idles at 50C with fans running at approx. 3500rpm when no apps are open. Used to idle below 2800rpm. Fans kick in big time and unit overheats with average usage ie Mail, NetNews, Safari. Cooking when I run FCP7.

I have read of solutions which some say work including rebooting at 32 Bit.
Is there a definitive solution or workaround that anyone can verify?

Since Apple didn't address it with 10.6.2 it must mean it is a bigger problem...
you wish they would at least acknowledge it. But then again they can't even get rational consistency in app store approvals. I've had one repeatedly rejected for a year now and every time it is something else after we addressed the last BS "concern."

I don't understand what you mean? of course it reloads when you load a video because its there to load 32bit plugins predominantly flash as you said.

so...even when its killed of course it will reopen when requested to by the browser.

Its a temporary solution because its not always an issue, sometimes it causes an overheating problem and if restarted it resolves it (atleast in my case.)

even if you instantly reload it then playback the same bit of flash you will notice a cool down...to be fair to apple, since the latest update for safari i havent noticed this problem yet.

(ps) you might want to start/find a new thread about that other issue because when it crashes it doesnt take safari with it for me, it hasn't once.

edit

additionally is there anyone out there running the latest safari update still having these problems?

After I did a repair permissions, the webkit plugin is now listed as 64bit in my Activity Monitor, while it was not before. Whenever I watch a show on Hulu, the temps and fans increase to the point where the MacBook is too hot to sit on my lap.

I also noticed that my "Safari Flash plug-in" is not 64 bit. I went to Adobe and confirmed that my Flash is up-to-date. Does this matter?

I updated Safari days ago.

This never happened with Leopard.

I mean that when WebKitPluginHost is not active it's not consuming much CPU (0-3% like many other background processes). And since it's restarted anytime it's needed, killing it doesn't really change much. Also my understanding is that WebKitPluginHost is the one running the 32 bits plugins, passing the result to Safari 64 bits (and that's why it goes high on CPU when playing Flash).

Anyway I tried now killing it while watching a video. I get indeed the blue cube. I thought it could confuse Safari and maybe crash it.

About the crashes I don't know. To me Safari just crashes as a whole, like before. Now I'll install the new release. Maybe it will fix it once for all!!
