Does the OSx Lion update 10.7.1 fix 2011 MacBook pro heat issues?

Hi Sue,

All three links you provide refer to exactly the same story, in fact they are the same wording for the most part to begin with. Spotlight & FileVault which they blame which both require intensive use of the hard drive, can also be due to hard drives installed that were not designed for the small space in the machine. Nowhere does it say if the machine has a factory installed hard drive or not. If that is an issue, certainly it would help to know if those hard drives were factory installed or not. Now if it is a factory installed hard drive, what is their other evidence it is overheating? Is it just that smcFancontrol says they are higher than a certain temperature they believe to be higher than normal? Now while I don't use FileVault, I do have Spotlight on. And what's even more interesting about that, is I've had this machine now for four years, plenty of chance to get a corrupted Spotlight index in the process of use. I've not erased this machine once. And it still behaves. And yes, I've had Spotlight on Snow Leopard, Leopard, Lion, and Tiger installed on the machine. As for the arrogance, I would like to find out the cause as much as the next person. Please start a new topic thread:

If you would be interested in learning how to isolate the cause. Just tacking on a me too post, to a thread does nothing to help, as typically you can't tell whose response is to whom. and it becomes unwieldly sorting out the replies from the other me too posts. Stop assigning blame without isolating an issue.

Hey Sue,

The first link, which is referred in the second, seems to be dead. Is it spelled correctly?

Hi Gerard,

It appears this problem is prevalent among the late model MacBook Pro's, after the redesign where the battery is embedded in the body (2010 & 2011). Also, there are complaints from MacAir users as well. Good luck and keep me posted.

I tried the first link and it works for me, however, I checked my bookmarks and found another link below:

This one worx. Reading...

Hi,

Did you check my previous post related to Citrix plugin issue and try to follow the process to switch off the related service which is causing CPU ressources to be used to 100% ?

See this thread : https://discussions.apple.com/thread/3191543

Okay, read it. Doesn't add much new factual stuff.

Decided to upgrade from 4GB to 8GB this afternoon. Looking to cure all the Safari induced powercyle solvable hangups.

(oops, risking another rant here).

Did not solve the heatproblem of course. It still gets blazing hot.

CPU around 140*

Memory controller around 150*

Enclosure bottom 99*

I upgraded to 8GB about six months ago which increased the performance in apps. I still get high Safari Web content and flash player CPU usage but primarily use Firefox these days. Downgrading to Snow Leopard 10.6.7, (although time consuming) was the only solution to my heat problem.

Hi...

I was having a similar problem with my heating MacBook Pro... After two days I found out that the installed free download 'AVG Linkscanner' (downloaded from the site of Apple, before I upgraded to Lion) was taking up to 85% of the 'processes' of my MacBook Pro, which leaded to a serious heating problem (see below).

After I uninstalled 'AVG Linkscanner' the temperature of my laptop went back to normal...

Maybe you installed this free software too...

HD: MacBook Pro 40°C

CPU A 62°C (before the uninstall of AVG Linkscanner: 89 tot 93°C…)

CPU 58°C

CPU Heatsink 50°C

Enclosure Bottom 33°C

Memory Controller 56°C

Northbridge 1 61°C

Fans:

Right Fan 2005 rpm (before the uninstall of AVG Linkscanner: 5371 rpm)

Left Fan 2001 rpm (before the uninstall of AVG Linkscanner: 5482 rpm)

Good luck!

Dirk

Note, heat up to 90C is quite normal. So worrying about 62C is pointless.

I have a MBP 2009 with 10.7.1 and i have crazy heat and fan issues i can't even play 1080p movies anymore , they said that the POWER MANGAMENT issue was fixed in 10.7.1 but it isn't

Hello,

After almost a month including the final os update, I've given up Lion and went back to snow Leopard. Well... hence the name! now I can get myself out of the paranoia , that my macbook pro is about to vaporize due to overheat...

Lion overheated my 15" macbook pro so bad.. I can only hope for a "real" solution soon so I can enjoy Lion again because currently it is not runable, at least for me.. I was afraid that some thing would happen to my lovely mac due to abnormal overheating... 😟

waiting and hoping for an update on this overheating issue ..

cheers,

My thoughts are, with any laptop there is too much heat from them, so I keep a COOLING PAD under them, even the mac book pro, and it does help the temp of my mac.

I have a 2010 MBP, I notice it does get hot. Lion vs Snow, I could not tell you a difference. However, I do use my laptop cooler to blow cool air across the base. I have a 1TB HD and it runs the same hot or cool. Some one did drill holes in the base to get better air flow. The problem might be lack of air flow ventilation. Get a chill mat or something that can blow air around the laptop. That's my recommendation.

My 2008 MacBook Pro started to run hot as soon as I installed Lion. I found that the VirusScan program was using 97% of the CPU and keeping the hard drive spinning. I disabled the "scan on access" function and the problem went away. Back to normal temps. In my 20 years of using Macs the solution to problems has always been rather simple. The hard part is finding it.

I think I might have found out the reason! If your Mac slows down or seems busy or acting in a way that is not normal, go to the Spotlight at the top right. The spotlight will show that the hard drive is "Indexing". I was getting frustrated, turning my Mac off and trying to stop all processes. That's when I noticed the indexing thing. Once it finished, it was back to normal. I never saw that Snow Leopard. See if this is happening to others. Go to the top right, as if you are doing a search, click on it and see if it was or is indexing.
