MacBook Pro Overheating [FIXED]?

For just the past few days, I've had the overheating and the fan working overtime as well. I thought I'd add my two cents here. I have recently added a couple of third party applications, one of which is Avast! antivirus. I looked at all the suggestions about hardware and thought I'd try a safe boot first to see if it was one of the bits of software I'd added. As soon as I safe booted, the fan stopped and the computer instantly started cooling down. I uninstalled Avast! and all is quiet and cool now.

I'm on a MacBook Pro early 2011 running Mavericks. So, just an FYI for those of you who might come here trying to find out what's wrong and may have loaded some new software that's causing your issues.

Hope it helps.

the fix in the OP brought my fan revolutions from 5000 to 4000 on average (using iStat to monitor temp and rpm)

my 2011 macbook pro gets taxed by running multiple tracks in Ableton Live (audio recording software)

honestly i didn't think unchecking "Automatic graphics" would do anything.. but it did, and it's so easy to change... thanks for the info!

IM running mac sierra love but it has a few bugs

I've had the motherboard in my 2011 MacBook Pro replaced 3 times (because Apple assumed the overheating was a GPU fault) but still the Mac freezes. I believe the problems may be related to the Crucial SSD drive and that it's confusing the temperature sensors. If I override the fan speed (with SSD Fan Control) to max 6200 RPM, the Mac doesn't crash (yet!). I've spoken to Crucial and they are hopefully sending me a replacement SSD drive (thinking it might be faulty) but I think it's a compatibly problem with SSDs and the 2011 MacBook Pro's temperature sensors.

(Also, I would suggest everyone tries a SMC reset first as this often fixes most issues)

Just received an email from Crucial with this interesting line:

Apple computers utilize a proprietary fan regulator adaptor that our drives do not have. In order to keep the fans working properly and keep the drive from overheating you would need to use a 3rd party software.

One guaranteed cause of an overheating macbook is a fake MagSafe charging cable.

I bought a Chinese made macbook charger (because it was significantly cheaper than Apple's, of course) and found that it began to overheat my computer; when plugged in, my laptop would operate at about 65 degrees celsius (150 F).

With my new Apple charger, I'm operating at about 45 degrees C (110 F), which is about the temperature it ought to operate at.

Don't buy fake chargers.

My 2012 Macbook Pro Retina has always run hot, which can't be good for the long term life of the machine. I checked Activity Monitor tonight, trying to solve a different issue, and saw that Carbonite was pulling a lot of resources. I paused the auto backups, restarted the machine, and saw temps drop from 56 to 33 C. I then turned Carbonite back on, and in the space of 20 minutes the temp has climbed from 33 to 56 C. So it's a software issue with my computer. Check your Activity Monitor, as CodyDaMan suggests.

This week I took my Macbook Pro Retina (2012) to repair for an unrelated problem and discussed the overheating issue with the service technician. He confirmed the issue with Carbonite, stating that it significantly contributes to overheating. Set Carbonite to "Low Priority" if you're using it and having problems with overheating.

He also cited dust as a problem with machine overheating. Find out where the fan vents are and blow them out with compressed air. Or better yet, take the machine in for cleaning.

I don't have the automatic graphic switching thing my laptop is a MacBook Pro mid 2009 unibody 4gb ram 2.53 ghz intel core 2 duo and i've already cleaned out the laptop fan and it's still doing it, it's burning my hands to type and stuff.

but in my laptop i follow your step but dont see any type of ( Uncheck Automatic Graphics Switching. ) option

well i don't find increased performance or battery saving in energy saver ??

When I uncheck the automatic graphic the computer stays on Lil longer but freezes then restart but this time without the blue & white lines but don't stay on what can I do now ?

Ok this problem I can fix you know about a software called gpx ?

Have you found a solution?
