Macbook Pro overheating issue

Hi,
I'm really concerned about my Macbook Pro temperatures, so I have installed an application to monitor it regularly. and I have found out that my CPU core temperature sometime rises up to 90 C. also my GPU heat looks unusual sometimes. is this normal? if it is not what should I do?

Hello again,
I've been monitoring my temperature since I have Posted this message, and I have found a few interesting things, I'm using Temperature by Marcel Bresink Software- System:
1. two parts of my MacBook specially gets hot, the top left corner just below my keyboard, where the battery is located. and the on the left speaker I can also feel the heat, but the other parts are cool.
2. It usually gets hot when I am charging or discharging the battery, so I'm suspecting there might be something wrong with the battery, although it is operating normally, I also suspect GPU, If I'm not wrong it must be located somewhere close to the left speaker, but I might be wrong.
The software I use to monitor the temperature usually shows a value, between 25C and 28C for the batteries, but I suspect either the software has a glitch and is not accurate or the sensors are not functioning properly, since I can feel the heat very clearly.
3. The temperature is always normal, when the batteries are fully charged and I am using AC power.
4. When using the MacBook with battery, the temperature of CPU, and GPU and other components rise to an average between 85C and 95C, but there was an occasion the MacBook got super hot and when I checked the values they showed 128C, so I immediately shutdown the system.
I'm using a cool pad, and also I don't use applications that require heavy resources and process by the CPU or GPU or RAM. But that doesn't help much.
I'm really getting worried about this. any ideas about what might be wrong?

Macbook Pro Wifi Issue

I incorrectly posted this in the wrong thread this morning.
I'm hopeful you might be able to help me diagnose a problem I'm having. I'll provide as much detail as possible.
I have a first generation MacBook Pro. As of this morning I was running 10.5.6 and up until this week was using a linksys router and a comcast cable modem.
I used to have a great wifi signal throughout the house (always full strength), and around 12-18 months ago noticed the signal would weaken. The best I would get would be minus the top bar on the signal, and usually only if I was directly above or next to the room with the router. There were no new phones or devices added that might adjust the signal. On the other side of the house, I would have no signal at all.
My wife has a nine year old ibook and has no issues connecting through wifi.
When I bring my laptop to her parents' house or to the Apple store, where they use Belkin on N or Airport Extreme, I get a full signal.
I've recently suffered a hard drive failure and had a replacement drive installed. The problem persists despite the software update.
Not knowing if it was a router issue or an airport card issue or a combination thereof, I went to the Genius Bar. The genius recommended I upgrade my router to Airport Extreme, and if that doesn't work to return it and he'd focus on the airport card or antenna. I could get the flat rate repair (no AppleCare at this point) for $320+ to repair the problem if Extreme didn't work.
I installed the Airport Extreme router and got a full signal in the basement, far side of the house, upstairs - everywhere. Until around 10pm. The signal died from the basement. If I walked into the room with the Airport Extreme router, I'd get a full signal. If I left the room, I'd get a partial signal. If I walked any distance (10-12 feet), the signal would die. I restarted both the modem and router with no change. I reinstalled the linksys router and got a depreciated connection. I restarted the Airport Extreme again and got a full signal throughout the night, morning, through restarts, and when I returned home from work.
Last evening after using youtube extensively it died again. Linksys would barely work if I switched back, and no matter how many times I restarted I couldn't get the signal to last outside of the area of the router. I left it in the basement overnight shut down, restarted this morning, and had a full signal.
I'm looking for any potential guesses as to what may be causing the problem. I don't want to replace the card if it's the antenna or sink too much cash into a machine if it's a heat related issue linked to Generation 1 syndrome.
During all of this the ten year old ibook works fine. I know a lot of macbook pros have issues with their wireless and don't want to sink in the cash if it's more complex than that. Any advice is much appreciated!

Hi nashie1002,

Can't install windondows 8.1 on my macbook pro - format issue

Can't install windondows 8.1 on my macbook pro - format issue
Running latest version of Mavericks.
Followed the exact bootcamp proceduce.
Have official window 8.1 version on cd.
All goes well until I have to format the 65Gb partition. Disk=0 and partition=4
Can't get over it. Altough I formatted it via a hint found on the internet with "dislpart" in NTFS. Wich also went weel and give the labelname "BOOTCAMP". But still no luck.
I have two questions:
1/ How to start my mac again in normal mavericks mode?
2/ How can I overcome the windows installation issue?
Tried already a lot of hints found on the internet.

First, make a time machine backup. You will need to erase ands reformat your hard drive. I had the same issue. The issue is that you can't install Windows using bootcamp without having the hard drive formatted as Mac OS Extended (Journaled). Do this from disk utility or recovery mode (hold down command and r at startup). Then you have to restore the backup to the hard drive. Then make a usb installer drive with bootcamp and then partition and install. Here's a tip: after you install bootcamp and are in the Windows desktop, go into the installer drive and then go into the bootcamp or support folder, then find a installer that contains the Apple bootcamp drivers. Also, you will need to convert the disk to an iso file. TO MAKE THE USB DRIVE FROM A DISC, USE THIS LINK

2011 Macbook Pro Overheating *VIDEO*

Well, I must say that I am really disappointed with the current 2011 Macbook pro lineup. This was my first Mac, I must say that I was really excited to finally own one. As I started using it, I noticed how hot the laptop was getting and how loud the fans were. While I was typing a simple E-mail, my palms were getting really hot and was a very uncomfortable feeling. I've been around friends who have own previous models and all have been very quiet and also fairly cool.
I started to get curious so I started reading the temps and it was a staggering 90c degrees! This was just while web browsing, having iTunes loaded and just doing normal day to day stuff. I immediately went online and did a Google search for "2011 Macbook Pro Overheating". I come to find out that it is a common problem. What was most disappointing to me was the fact that Apple is fully aware of this problem and has disabled Turbo Boost on the 13.3" Core i7 while running Bootcamp. So technically speaking, your better off buying the Core i5 model as it will run faster.
I decided to return the laptop, I feel it's deceiving to buy a product that really doesn't perform at it's full potential (It's like buying a Ferrari and only be able to go 60MPH). My batter life was also terrible, I was lucky if I got 3.5 hours under normal web browsing. I think this had a lot to do with the fact that the fan kept spinning at full speed every 2 minutes.
I hope this post doesn't come off as a flame, but rather constructive criticism on Apple's design to improve their products. I truly believe that Apple needs to redesign their Macbook Pro lineup to accept modern processors that run a lot hotter compared to when the Macbook Pro was first introduced. The fact that it has no ventilation in the bottom like every computer out there poses a huge problem with newer processors. I understand the aesthetics portion of the design, but I would much rather have a few small vent holes to keep the processor running cool and maintain a longer life for the hardware.
Lastly, before anyone say's that I got a "defective" one I want to say that this was my 2nd 2011 Macbook Pro as the first one was returned due to the same problems. Here is my video of my experience - http://www.youtube.com/watch?v=6_azMBStJnY

I am having a similar problem. Bought MacBook Pro 17" 16 months ago and after about 9 months, routinely, daily, but no particular time I got a black screen suddenly.
(This is running Windows 7 all the time.)
So daily it has been doing this except for a 3 week visit to Europe ... weird. Yet while in Europe no change in usage. Software or hardware. Except that in US I have it plugged often into a bigger monitor. And sometimes have lid closed but not for the past month while being back.
Return to US and within 2 weeks, suddenly black screen of death anytime during the day, keyboard in use or not.
Called Apple finally yesterday ... they need to know if it happens under Apple IOS. No idea. So for 1 1/2 days ran Apple and did nothing! No black screen.
But what I have noticed is that when it does go black the bodyis HOT!!! Especially between the screen hinge and F keys to the left.
Today I did two more things ... installed gotomypc to see if when it goes black if the laptop is functional, just dead video. I will try to remote in when it goes "dead".
Also I put a load of coins on the laptop where it gets hot to absorb the heat and do they ever!
One thing ... the first time I ever saw this black screen symptom it RECOVERD after 3-4 seconds and gave off an error message like
“Display driver stopped responding and has recovered” error.
So based on researching this, it sounds like the video card needs replacing OR a driver update OR a bath in cold water?

Macbook pro shutdown issue when I push the power button it immediately goes into sleep mode

Hello Marrio22,
Thank you for the question. With OS X Mavericks, the power button has new functionality:
OS X Mavericks updates the power button behavior on Mac computers.
Using the Power Button to Sleep & Wake
Tap the power button in Mavericks to put your Mac to sleep or to wake it up:
Tap the power button once to put your Mac to sleep.
Tap the power button again to wake your Mac.
Press the power button for less than a half a second to sleep or wake your Mac. This duration is similar to pressing the Space bar or Return key to wake your Mac. The power button works this way across all Macs using OS X Mavericks, including both notebook and desktop computers.
Accessing the Shut Down Dialog
Press and hold the power button for 1.5 seconds, to bring up additional options:
Forcing the Mac to Turn Off
Hold down the power button for 5 seconds to force the computer to turn off. Important: You may lose unsaved documents if you force the computer to turn off this way. Use this method of turning off your Mac only if it has become unresponsive for an extended period of time. Normally you should shut down the computer by selecting Shut Down from the Apple menu, or from the shut down dialog pictured above.

MacBook Pro overheating after security update

Why is my Macbook Pro overheating?

None of your images are displayed. If you could try again it might be of help.
118° f is satisfactory and not to be alarmed at. Aperture certainly can increase the temperature. I surmise that your MBP is a pre-unibody model.
Here are the list of videos from the OWC web site. Choose the one for the model that you have, 15" or 17" and look at one at replacing the HDD to understand how to take the top cover off. Having an older MBP, you may have dirt and dust inside that should be cleaned out and this is the only way of accessing it. Contaminants can be a cause of heat buildup.
http://eshop.macsales.com/installvideos/
You will need a #00 Phillips and a #6 Torx drivers for this. I suggest doing this on a clear table with a towel underneath. That way you can slide the MBP easily around and if you drop one of the screws, they will not bounce far. Sequence is important and taking off the top cover should be done with care so that the ribbon cable is not damaged.

Macbook Pro overheating Apps "Quit Unexpectedly"

PROBLEMS WITH MY UNIBODY MACBOOK PRO
GPU/CPU Problems? Logic Board bad? I'm not sure what the issue is. Please Help!
Hi, I have an:
·   Early 2009
·   17 inch
·   Unibody Macbook Pro (UMBP) (5,2)
·   Intel Core2Duo 2.66GHz
·   Nvidia GeForce 9600 GT 512MB graphics (kept on Performance mode – not power saver – because it usually sits on my desk plugged into AC wall-wart 85watt mag-safe power like an iMac), (Nvidia GeForce 9400M onboard too)
·   I have an external 27” monitor connected and mirrored - with the internal screen off (brightness is all the way down – thus running cooler)
·   (Note: all the problems existed before any/all my upgrades – including the external monitor.)
·   I have upgraded to 8Gb’s of 1066 DDR2 RAM
·   500Gb Seagate Hybrid HDD
·   The UMBP is Running the latest OS 10.8.4 (with automatic updates) – and it had the list of problems (below) with OS Leopard, and Snow Leopard too!
1) It will not play *Netflix streaming*, or youtube or any other internet video without stuttering, stopping, and hesitating in video and audio!! I have CHARTER Cable Internet which runs between 20-50Mb’s :-) This is NOT slow internet.
And with my Windows 7 (64bit Intel QuadCore) Desktop PC using the exact same wifi internet connection there’s *No stuttering*, no stopping, no hesitation in video OR audio! It’s an older Gateway desktop with a tiny USB wifi dongle. And the desktop runs *on-board* Graphics – no graphics card in the machine...at least not until I upgrade the power supply – then I can install one. ;-)
2) System Information crashes - “Quits Unexpectedly”. SOooooo frustrating! I can’t even get the current specs so you guys know what we’re dealing with. So I looked them up in a file I have kept since I did all my research online to buy this UMBP. So, I copied all the data that was just now sent to Apple (not that anything will be done with it – they don’t care – my Mac is out of warranty). This app crashing has happened *numerous* times in the past couple years and I just didn’t know what to do about all these problems (the list continues below) because it’s been out of warranty since before I bought it used on eBay.
3) I canNOT get Adobe Reader to run on my UMBP - it crashes within seconds! I finally uninstalled it and re-downloaded it and then reinstalled it – still same problem. So, I waited a few months and then re-downloaded it and re-installed it again – still same issue. And I know that Reader had been updated more than once in that time.
I think that the following is unrelated but I figure I should put in all the information I can. The battery never says 100% (it’s always between 97-99% full. When I first got the UMBP it kept telling me to get a new battery (for $250!) And the seller sent the UMBP with a 65 watt (not 85 watt) mag-safe power supply…which I didn’t even realize until months later (hey, this was my first and still is my only Mac, so ya gotta give me some grace here. I hate(d) Microslave *so much* after living with WinVista for 2 years that I HAD to get a Mac..and I don’t ever want to go back! ;-) The only reason I even have a Windows box is because a friend of mine (who was borrowing my then spare beat up old car for like 3 months) gave me one when he got it as partial payment for a job he did on a small business network (yeah, he’s even more geek than me!)
At first I was thinking that it was the NVidia GPUs, but now I’m beginning to think that all three: the CPU and both GPUs are in need of re-soldering to the Logic Board. It seems that I’m not the only one online that agrees that the system cooling fans are subpar in UMBP’s (lots of complaints about burned fingers, etc.) – so, I run a small 6 inch fan (on high) across the top of the keyboard 24/7 so that it won’t completely fry! (Well, at night when I put my UMBP to sleep I usually turn off the fan…but anyway.) It doesn’t wake up at night to do any background downloads or Time Machine (USB ext drive) work – it would most likely wake me up if it did (I’m a very light sleeper). The fan does a good job at keeping the surface (aluminum) “warm” (as opposed to HOT) so that IF I were to use the built-in keyboard I wouldn’t burn my fingers (like I used to – until I bought an external Bluetooth Apple keyboard – those keyboards are so nice!).
So, yeah, I could send it to someone on eBay (along with $200) who will reflow or reball the chips to the Logic Board, but that seems to be a band aid on a situation that is quite likely to happen again…right?
As I see it: Apple didn’t put enough cooling into the system – the fans are too slow/small – and thus I have a serious problem with the Logic Board.
And I was just on eBay looking at Logic Boards and they cost at least as much as most of the UMBP’s like mine. So that would be way too expensive – I might as well just buy another UMBP like mine – but that’s not going to happen.
The closest Apple store is 2.5 hours drive away from where I live. And the closest authorized apple repair shop is 1.5 hours away and it’s not likely that they will run system tests for free…and the Best Buy here in town is not authorized to work on Macs – they didn’t show up in the search results at locate.apple.com/service/….
So, what can/should I do??
I didn’t write all this just to “vent” – I really need this fixed!
ONE SMALL ADDITION:
IF ANYONE suggests that I do the following:
> System Preferences > Energy Saver > Graphics: Better battery life
(Previously it was set to "Higher performance")
Then I will…do something (hmmm it’s the internet, what can I do??)…for their IDIOCY!!!
Doing that *is doing this*: Paying $3,000 for a Macbook (NOT Pro!!)
I mean think about it for one second: the specs on the Macbook is the cheaper/slower Graphics Chip (GPU) and buying a Macbook costs THOUSANDS OF DOLLARS LESS than a MBP! Right?
IF Apple suggested doing that then that is just Apple’s lame-a$$ way of trying to get away from the fact that they underpowered/under-designed the cooling system (fans et al).
That’s the same answer I got from HP when my notebook overheated to the point of dying!!! HELLO?!?!?
Get it? ALL these notebook manufacturers’ designers and engineers are all using the same data/designs! Yet, I’m paying TWICE THE PRICE for an Apple product (expecting a cool running notebook) vs. a custom-built HP 17” notebook PC that I bought brand new a few years ago (with Vista – ARGH!)! One which would run simultaneous DUAL EXTERNAL monitors at 1080p! That GPU kicked butt! AND it had DUAL SATA2 INTERNAL Hard Disk Drives (with the internal DVD burner)! And this was made in 2009 people!
I thought Apple cared more! Especially at this price!
Maybe you DON’T “get what you pay for” anymore…?

2008 Macbook Pro overheating problems

I have a 2008 Macbook Pro that I recenetly upgraded to Lion, it seems like Lion has made the overheating issues worse. My fan is almost constantly running despite being on a cool table. Is there anything I can do to make the overheating stop? I have tried resetting the battery but that did nothing. Thanks!

Try resetting the SMC:

If that does not help, install iStat pro (from the Internet-free) and post the temperatures and applications that you are using at the time.

MacBook Pro Heat Issue

I just recently received my MacBook Pro this past Wednesday and I've been addicted since. This is the first Mac I've ever owned and felt it was time to move onto something better and more stable than M$. I do use Linux but it doesn't have near the support like Mac does except maybe Suse (only because of Novell).
My problem is my MacBook Pro gets very hot. I've read the entire book that came with my machine and I noticed that it said that the operating temps are between 50-95F (10-35C). Am I reading/understanding this wrong? I've performed average use of my machine and have used a Class 2 Laser thermometer (made by Stanley) to take the temp and i've reached up to 115 degrees F just above my function keys.
If i remember correctly from left to right it goes Northbridge, GPU, and then CPU. The 115 mark was at my CPU on the far right side. I also never hear the fan on this machine come on. This is the quietest lappie I've ever heard after extended use. You hear the fans spin up all the time in the Dells, Gateways, Compaqs, etc.
One of my coworkers turned me to the overheating issue with these machines and it made me quite nervous. I understand that they had somebody who had cerebral palsy apply the thermal grease. What i gather and understand is that is now become an insulator instead of an adhesive. Is there a Real way to remedy this situation?
I've read stories of people having this issue and stating they took the machine apart themselves, cleaned up the goop, reapplied AS5 and their temps dropped (from reports) 15-25F and even only 2 degrees F. I know that silicon can take a beating in the heat but i'm kind of worried about the other components in my machine.
Is this firmware update really going to make a difference or is this some form of coverup? I'm being cynical now but i'm worried that such a great product is going to be a very large paperweight. I ran tests on my old Gateway 600 series laptop (top of the line when i got it) and it hangs and about 98-99F at its high points. The fan also kicks on and is loud as **** but seems to cool it enough to be reasonable. Although, this machine does make me quite warm when sitting on my lap.
Does anyone have ANY ideas as to what can be done? Or what have you done to try and remedy the issue? Am I doomed like the rest of you that have this lappie? I haven't seen anything from apple about this issue other than some firmware update.
Thanks for the help and ideas in advance!

Master P, you did misunderstand Apple's specifications for the range of operating temperatures. Those specifications apply to the ambient environment in which you operate the computer. In other words, Apple recommends against using your computer if your room temperature is at 95 F or above, or below 50 F -- temperatures that would be uncomfortable both for you and the computer. Of course some people such as photojournalists do productively use their MBPs in extreme environments such as the Sahara Desert or the upper slopes of Mount Everest, but I'm sure they understand they are reducing the life expectancy of some of the components, such as the hard drive in the computer.
A temperature of 115 F or higher on the metal strip behind the function keys is perfectly OK. You don't need to touch that strip to use the computer. My criterion is whether the parts that I need to touch remain comfortable -- the keyboard, trackpad and wrist rest areas. They do on my computer, although the left wrist area can reach body temperature after extended use.
In my opinion the recommendations to remove and reapply thermal grease fall into the Urban Myth category and do not make technical sense. And performing that "fix" will likely void the warranty and an AppleCare policy, should you subsequently have a logic board or CPU failure. The "fix" will be immediately visible to Apple service folk should the computer have to be sent in for repair.
No, you are not doomed. My CPU temperatures after hours of operation generally run in the 40 to mid-50 C range, depending on what I'm doing. At the moment CoreDuo Temp is reporting 48 C. Continuous 100% load of both processors for extended periods results in CPU temperatures in the 60s-70s C, which is well below the maximum continuous operating temperatures specified by Intel.
The SMART disk temperature of my 7,200 rpm hard drive has always been reported by Hardware Monitor to stay well below the operating temperature maximum of 55 C recommended by Seagate.
So I expect to get years of useful service from the MBP.
Both because I like the tilt for typing and because it provides an additional heat sink to cool the computer in heavy use, I use an aluminum tilt stand whether the MPB is on my desk or in my lap. I use a KoolSink because it's very portable, but there are many laptop stands that work well.

Macbook Pro overheating after OS X update (10.10.3)?

After update my Macbook Pro is overheating, mainly the HD, anybody with the same issue? or how i can fix it?

Please see this Apple article:
Runaway applications can shorten battery runtime, affect performance, and increase heat and fan activity - Apple Support
You need to make one minor change in the procedure with OS 10.9 and 10.10. In the vry importatn Step 3, you are shown how to make Activity Monitor (AM) show all process instead of the default "My Proceses." Starting with OS 10.9, the option to show all processes was moved from the window's toolbar to AM's "View" menu:
Another suggestion: AM will not pick up all the bad actors if you do the procedure immediately after a restart. Use the computer normally for a day or so before doing the test,
Another common cause of overheating are third-party anti-virus or so-called "cleaning/optimization/tune-up" apps. They casue many more problems than they claim to fix and will make your Mac run like a 15 year-old PC.

17" MacBook Pro Heat Issues

Hi everybody, I recently got a 17" MBP but have been having some issues with heat. I have been looking into the issue online on various message boards, have read extensively on the thermal paste idea (though have not opted to attempt this yet), etc. My serial number is W8621, so it is not a very early model afaik. I have been using the computer daily for good amounts of time, at first on my lap, but after that became unbearable, on a hard surface. I do have the SMC update. I hope I am not forgetting any important information.
Anyways, I have been struggling with the heat which I have recorded using Speedit and CoreDuoTemp to be between 65 and 75 degrees C idle and exactly 90 degrees load (using yes > /dev/null, I know some people argue over if this really stresses the system to the max, but for my purposes I think it shows my problem well enough). I have even recorded a peak temperature of 94 degrees C, or a scorching 201 degrees F. All of this translates to an untouchable case at various points including the bottom, the left side, and the keyboard (both the bottom near the space bar and the top near the F keys). I know these machines will and do run hot, but I think that mine is running especially hot and I am looking to ideas on what to do. Though I probably would have no issue redoing the thermal paste I would rather go through more official ways of fixing the problem. I did get Applecare with the computer so I have plenty of time to take it in, but I was wondering what if anything they could do, because last I have heard they don't really acknowledge the problem.
Anybody with similar issues want to share their experience and what they told Apple was the problem? I don't want to go into my Apple store only for them to tell me the paste is not an issue, or the heat is within spec, or that there is nothing they can do.
As if this wasn't enough, it seems that I have developed the 'whine' problem over the past day or two. I first heard about this problem a day or so after I got the MBP, but never noticed it or heard it even when trying to, so I thought I got by with a working one. However, over the past day I have noticed a high-pitched sound that varies in pitch slightly but is on almost all the time, with slight pauses ever 20 seconds or so. This occurs with the power cord plugged in, as it has been since I have got the machine. I have not had the computer unplugged for an extended period of time (over an hour) since I got it. I have not attempted any fixes, and honestly don't want to, but again if this is a decent reason for them to check it out I would appreciate any advice. It is gradually going from noticeable to annoying, and I am starting to get upset with my otherwise beautiful and perfectly working computer.
Thanks in advance for any help! If you need me to post anything else just let me know, I really want to take care of this before I take it to school in the fall.
17" MacBook Pro Mac OS X (10.4.6)

Maximum PC Magazine had an article about the MacBook Pro's heating problems in the May 06 issue. They basically said that after opening the case up, they noticed that Apple was applying a huge chunk of thermal paste between the CPU and the cooling element.
Applying too much thermal paste to the CPU is actually bad. It will act as an insulating barrier causing heat to build up rather than dissipate through the cooling element.
So after they scraped off the thermal paste gunk, they reapplied some Artic Silver (the best thermal paste on the market) to the CPU and noticed about a 10 degree Celcius decrease in temperature.
Apple's only official response to overheating has been that sometimes people forget to take off the packaging tape covering the vents.

Anyway, food for thought....

Macbook Pro Overheating and Lagging

Hi.
About 2 weeks ago my macbook pro began lagging a lot. At first I thought it was my flash player, since it was lagging videos and flash sites on every browser, but then I realized it was lagging on programs and applications as well, such as Skype and Photobooth.
I called apple support twice, and after helping me with some memory issues and some update issues, the lag still persisted.
I visited an apple store today and brought my laptop to the genius bar. It wasn't laggy at the genius bar, although maybe it simply hadn't overheated in time (I didn't think it was overheating until after I returned home).
They formated my laptop and I thought that would fix the problem but it didn't!
It lags like crazy when I run a website or photobooth or anything, and I noticed the laptop gets REALLY hot really fast. I'm not sure if it's overheating for sure, but I would like some more suggestions before I take a second trip to the apple store (which is far from me).
Thanks!

for lagging problem,you can solve at Disk Utilitty ( repair disk permittion)
for averheating, you can try to install Gfxstatus( googling,its freeware). Use this aplication to monitoring overheating issue,we can control booth of fan.to minimize heat.
good luck.

MacBook Pro Overheating, Fans Won't Kick In Appropriately.

So the issue here is simple.
1.) When I am playing a game (normally Counter Strike Source) my MacBook Pro will become very hot very fast. I play natively through Steam for Mac so I am not using Windows.
2.) When the computer is doing intensive things it seems, the fans will kick in accordingly doing what they must. However when I go to game, and the heat it at the upmost, the fans sound like they turn off as if the computer is just sitting there idle. I can watch my temps in iStat control and temperature monitor. And after about 10 minutes of play, my CPU is 100+ C (around 102 before the drop)
3.) After this point, my FPS (Frames Per Second) in game are more than halved. The game seems to take a massive hit in performance and everything is choppy. I know this is because it overheated and kicked down the clock speeds on the CPU / GPU to save it.
-- I am not sure why the fans won't kick in. I know that they are working, so I got SMC fan control and also tried the fan control through iStat menus. I can set them to medium and they will turn on. And I am able to game all day with no issue. However should I set control to default, the fans seem to not turn on when needed and let the MacBook overheat. I feel like this is a software issue of some type. I do not understand why though. I know my fans are working. I am playing on the same desk I have been for months with no issue. This literally started out of nowhere one day when I was playing.
I did not have any type of fan control software installed when this happened originally, but since I have installed SMC and iStat menus that has controlled it and allowed me to game, however it's quite annoying to have to be manually setting fan speeds all the time.
What should I do??

Same here. I am using Parallels and when launching games through it the fan doesn't go over 2,000 RPM when CPU is at 98% and way over 90 celcius. I am forced to then start something processor-intensive on OS X to get the fan going faster. There's a bug in there somewehere.

Advice appreciated on a MacBook pro HDD issue

Hello,
I've just suffered my first real system problem and even though I have a few ideas for how to fix it I thought I'd post here and ask for some advice to see what you guys think.
First the problem... Basically my MacBook Pro's HDD has an issue and won't boot. I don't think it's a physical problem with the hardware (although I'm open to advice on this too), I think it just needs a reformat and fresh install of the OS. But obviously I need to get my files off of there first and this is the problem, but read on for more details.
So that's the problem in a nutshell, but here's the full detail.
It's a MacBook Pro, late 2011, 17", 750GB HDD, 8GB RAM, bought in Miami September 2011 while I was on holiday there (I live in the UK), came with Snow Leopard installed, was upgraded to Lion a few days after purchase and then upgraded to Mountain Lion about a month ago.
Last week I was using it when it suddenly restarted itself. I let it restart, then began using it again and about five minutes later it restarted again, but this time it didn't boot properly.
It stayed on the grey screen with the apple logo and spinning clock-type wheel. There was a progress bar at the bottom of the screen, it took ages to move, then finally got to about 33% and the machine restarted itself again.
I tried lots of restarts but every time it did the same thing or it never even showed the progress bar, and just had the spinning clockwheel forever.
So I held down alt and booted from Mountain Lion's recovery partition instead. I launched Disk Utility and tried to verify / repair the drive but it came back with errors and said that it couldn't fix them. Apologies, I realise typing this that anyone reading would probably quite like to read the error long but I can't remember it and I'm not currently at home. If needed I'll run it again and post.
Anyway, the basic point is that Disk Utility is giving a message saying to copy all my files off the drive and reformat because it can't fix it. Incidentally the SMART status of the drive is fine / normal. Not showing any problems there, which is why I'm hopeful it's not a hadware issue.
So I need to copy my files off, and this is the real reason I'm posting this thread, because I don't mind doing a reformat / fresh install of Mountain Lion, but my last backup is a couple of months old (I know, naughty me) so while it wouldn't be the end of the world to copy files back from that, I would lose a bit of data so would like to get them off the MBP's HDD now.
At this point, let me list the kit I have at my disposal:
- At home I have the aforementioned patient (MacBook Pro), a 2TB external HDD with USB2 / FireWire 800 and a NAS box that sits on my network. I also have one of those cables that lets you connect an internal HDD via USB (more on this later, as I suspect it's going to be my best hope).
- At work I have a Windows 7 PC which I do not have any admin rights to, A Windows XP PC that I do have admin rights to and an iMac that is running Leopard (10.5.8) and cannot be upgraded due to various boring work reasons I won't go into here.
So the first thing I tried was booting into the recovery partition, launching Disk Utility and trying to clone the HDD over to the external 2TB drive I have. Cloning the drive like-for-like gives an error message (again apologies, I can't remember it) and trying to copy to an image file on the external drive gets all the way to the end (takes ages because Disk Utility keeps going to sleep) but then when I try to mount the image it gives an error and fails, so I don't trust this method.
So booting to recovery and using Disk Utility seems to be no good.
I thought about trying to take the MBP to work and launching it in target disk mode, then copying files, however I read that you can only have one FireWire device (the target computer) connected when doing this and my iMac at work doesn't have enough internal HDD space to copy all my MBP's files off, so I would need to have an external drive connected to the iMac in addition to the MBP, which sounds like it's not a good idea, or not supported by Apple anyway.
I thought about making a bootable Mountain Lion USB stick as I have a 16GB USB stick I could use for this, however I don't know how to make the bootable USB using my iMac as it's on Leopard (can't be upgraded for work reasons) and doesn't even have the Mac App store on it for me to re-download the Mountain Lion install file.
I think I have the Snow Leopard DVD that came with my MBP so could probably boot off this, but does that allow me into Finder or anything that would let me copy docs from my internal HDD properly over to the external drive? Or is it just going to look similar to the Mountain Lion recovery partition, with Disk Utility and a few other options?
I don't know whether the Mountain Lion recovery partition lets me install Mountain Lion onto my external drive? Or a USB? I was a bit scared to start clicking through options to see whether it would ask me which drive I wanted to install to, just in case it doesn't and begins erasing the main HDD as one of the first things it does.
So this leaves the cable that allows me to connect internal drives via USB. This cable has saved my bacon in the past and I suspect it may be my best option once more. Obviously this means I'm going to have to open up the MBP and remove the HDD but I installed the extra RAM myself and I've installed full-size (3.5") HDDs in the past so I should be able to handle that, unless there's anything radically different with 2.5" drives I'm not aware of.
I've heard people mention DiskWarrior in the past but to be honest if I'm going to spend that sort of money I'd prefer to just put it towards an new, larger HDD, probably a 2TB model.
So there we are, thanks for reading this far. If you have any advice about another (or better) way to get my files off the MBP I'm all ears.
I've never actually done a fresh install of Mac OS before either, only upgrades downloaded from the Mac App Store so any advice around that might be handy too, but mainly it's the file copying I want help with as I'll probably just boot from the recovery partition to reformat and reinstall Mountain Lion.
Thanks

Yes, on your profile.. But, did you phone update just before this happened?

Mid 2010 Macbook pro "overheating"

First off let me just say I know there are many threads about this already - but all of them have the same kind of answer "the Macbook Pro is not overheating unless it turns off, keep it well ventialted and on a flat surface" etc, etc. I'm not complaining about my macbook "overheating" per se, but rather it is getting hotter a lot faster than it used to. I had a number of problems recently with my macbook and got it sent away to an authorized apple support centre where they replaced the cable that connects the logic board and hardrive (I'm sorry I don't know the technical term for this or even if this is exactly what they did. I know they replaced some faulty part that connected something with the logic board). And all the problems relating to that ceased - however about two weeks later and my macbook started heating up a lot quicker. The fans come on after about 5 minutes of casual use (internet browsing or word processing), and after about 15 inutes of doing something like watching a movie the fans are roaring away and the back bottom of the macbook is nearly too hot to touch. I've remedied this a little bit by only using the laptop at my desk and sometimes propping it up to give more air flow to the bottom but I never used to have to do this. Previously, I would have to be doing something pretty hefty for the macbook to start the fans even at the lowest speed. I was wondering if anyone knew of how to fix this? Whilst it's not a huge problem it is an annoyance and I don't know if it's a coincidence or not regarding the fact this started only a week or so after it got fixed. Any ideas??

complexcraziness,
try this next: log in as your administrative user, and create a new standard user — say, “Test”. When you’re done for the day, shut down your MacBook Pro. In the morning, boot up and log in as the Test user, without doing anything. Does it still rise to 71°C within a few minutes of doing nothing as the Test user?
Did you leave the MagSafe adapter attached overnight? If so, then another approach to take would be to change the Battery values in the Energy Saver pane of System Preferences so that the Battery and Power Adapter settings are identical. Shut down tonight, but detach the MagSafe adapter after shutting down. In the morning, boot up and log in as the same user as this morning, but don’t plug in the MagSafe adapter — just run on battery power. Does the same rapid rise in temperature occur when running only from the battery?
