MACBOOK PRO & SNOW LEOPARD - OVERHEATING

Can you explain this further? - - "it did not work the first 3 times"
Did you let the the apple sign chime 6 times or actually go through the re-start process 6 times. You also took out the battery and held onto power 6 separate occasions? That seems like overkill but if it works it works.
The fact that we have to go through this is just awful though--makes me feel like I have a dell $500 laptop and not a $2000 macbook pro :/

Confirmed. Moving to growl 1.2 (64 bits) now my temp went below 50 C. It already stabilized to 55C before for unknown reasons. At the first Snow Leopard install it used to be 70C.

Late 2008 Macbook Pro... same problem without running any GROWL version. This is very disappointing! I didn't have any problem running Mac OS 10.5!

I have this same problem. It can happen when all I'm running is Safari. My MacBook Pro gets so hot that I can't use it on my lap without scorching my legs.

While I don't have a fix, there's no question that -- in my case at least -- the culprit is the Flash plug-in for Safari. When the fans begin to race, the Activity monitor shows Flash to be using 180% CPU. This often happens when there is no video window anywhere on the page I'm viewing.

Restarting Safari solves the problem for me temporarily (sometimes a day or two), until Flash for some reason decides to freak out again...

Hi

Also my Macbook model 2008 is running hot since upgrade to snow leopard. With the previous OS I hardly ever heard the vents but now it is making noise like a windows vista machine - awful. The processor heats to 78 degrees C right now while I am only running safari.

Hope that we will get a patch from apple soon.

Just another voice chiming in - mine is doing the same (overheating) since the SL upgrade.... It was never this hot prior. (late 08' model MBP)

I just wanted to say I also have/had the fan problem on a MacBook2,1. I seemed to have solved it by disabling Carbonite (off-site back up software). Using iStat I could see that by cpu and network usage was cycling up and and down and the fan was running at 6200 rpm, after turning off Carbonite all this activity stopped. To be fair Carbonite is not supported on 10.6, but should be updated this month.

The interesting thing is that like Growl (old version) opening the preferences pane for Carbonite requires that the entire Systems Preferences application restart.

have you tried this:

and this:

and downloaded and installed the latest Flash Player:

and repaired your disk permissions:

Well, I thought updating to Growl v1.2 would solved this problem...but...no. So now, it seems that this problem occurs in relation to VMWare Fusion (running a Win7 or Win Vista VM). And always happens when playing Flash video...in any browser.

I have:

1. Reset SMC...twice
2. Reset Drive Permissions
3. Updated to latest version of Flash
4. Updated to latest version of Growl

Nothing seems to really improve the situation. I wonder if this has something to do with Grand Central Dispatch in relation to the previous version of Intel multi-core procs. That's the one core thing that changed with Snow Leopard that I can think could cause this.

APPLE...WHAT THE ****!!!!

im also another person having this problem and this *****. it only happens when im streaming movies but the other thing is my computer also seems slower now too. if i stream a movie for more than 10 min my computer gets real hot and disconnects me from the internet and i have to restart my computer in order for me to reconnect. i tried what people on this forum are saying but nothing works. i also called a mac specialest in my area, the apple store, and best buy and all of them said they havent heard anyone complain about this? what the **** is goin on?

Did my SL upgrade earlier today, before I red this thread...
MBP 2.6GHz 4GB RAM Early 2008.
Before Upgrade temp around 55 C low RPM 1500 to 2500 on FANs, after upgrade 65 > 81 C RMP 4000 to 5000 iPhoto gives 81 C
Growl updated as per this thread...
With only Safari open 61 C
Very big disappointment! Grrrrrrrr...

Any ideas??????

I thought I was the only one with this issue--overheating of SL on a macbookpro. I've already replaced the video board because of overheating. Now whenever I open mail and iCal at the same time, it practically fries my thighs...and the fans sound like jet engines. I called Apple and after a 1 1/2 hour phone call talking to 4 different techs, they said it was a "hardware" issue ant to take it to the Mac store. You'd think that at least one Apple engineer would might just browse these forums once in a while. Anybody know how to get this info to Apple???? I'm about ready to nuke the hard drive and go back to good ole' Leopard. Very sad.

its comments like joewacos that makes me think that this wont be fixed or cant be fixed with an apple update. are we sure that apple is working on this or not? how do we know? do we all have to bring our computers to an apple specialest and pay them to do something?

this is not a miner problem. this is a major problem that deserves a big apple annoucement to apple customers on whats going on. why is there nothing like this going on? i just dont understand it and its getting real annoying and i have no idea what to do about this?

Hi, I have a Macbook Pro. Intel Core 2 Duo 2.8 Ghz/4Gb 1066Mz DDR3 SDRM/128 Gb SSD. Purchased 2008-10-20.

I used to be very happy, my new and expensive SSD disk was totally silent and my fan never made a noise, only on heavy renders. Since I installed Snow Leopard, it's been on a constant buzz. My computers CPU is for most times above 70ºC, which cannot be healthy! This cannot happen from only using Safari?! Only starting softwares like iPhoto or After Effects, sets the temperature sometimes above 80ºC! That's WITHOUT rendering anything.

My colleague got an even newer Macbook Pro, same thing has happened to him. Besides this problem with the temperature, we both experience that software crashes 3 or 4 times more often than before upgrading to Snow Leopard.

Did I pay for letting Snow Leopard burn out my Macbook Pro? If no solution is presented soon, I will have to go back to Leopard.

It might seem stupid, it actually felt stupid doing this 6 times but I did. And strangely enough, after doing my 5th SMC and PRAM/NVRAM reset, the fan stopped bugging me and the temperature is a bit lower. The CPU temperature is now around 62ºC with iTunes, Safari, Mail and Stickies up. The fan and temperatures went up again with some rendering in After Effects. But that's to be expected.

Here's a technique I developed to do both SMC and PRAM/NVRAM reset at the same time (works on Macbook Pros purchased in late 2008 and after that, not the ones where you have to disconnect the battery).

*SMC and PRAM/NVRAM Reset*
1. Turn off computer.
2. Shift CtrlAlt and Power button.
3. Wait 5 seconds (you know it's working if the computer doesn't turn on when you click the power button).
4. Turn on Power button.
5. Quickly press and hold down Alt Cmd+PR (before the grey window).
6. You will hear the startup sound. Keep holding down. Let go when you hear the computer restart with a second startup sound.
7. Let the computer start up.
8. Do the same silly thing 5 more times.

Tell me if it works. This is no logical fix, but – this kept me from downing to Leopard.
