MacBook Air Mid 2012 Yosemite overheating

Just upgraded to Yosemite and noticed fan running and machine getting hot. Anyone else having similar problems? Im also having Memory Full issues (2 in 12 hours) yet I have plenty. Any help would be great.

Intel HD 4000 1024MB

MacBook Air, OS X Yosemite (10.10)

Ok. Trying again. 🙂 punishment welcome. After painfully reinstalling Maverick 5 days ago I was directed by an Apple Employee to "give it another shot". Remember my warranty expires in 2.5 months via Amex so if Yosemite isn't working I need to know now verses 2.5 months from now.


Yosemite is installed for the second time and everything seems ok. I've been on Safari for 45 minutes (10 minutes of video) without the fan kicking on. Thats a good start. I did allow the Macbook Air time to cool down after installing the new OS. It was hot after install.


During install I turn on "never" sleep and "never" turn off screen. Downloaded via wifi. It seemed to take longer then the first time yet I have no proof.


The Activity Monitor is looking good and the the device is cool NOT warm currently. I'll use it most of the day tomorrow and report back. Any feedback if this is helpful would be great.


The Apple employee today told me to bring the Mac Air in if it heats up after install and they would put a clean install on and try one more time before making there final verdict. Good idea on my end. North County SD Location.

This morning I wanted to recreate the overheating or confirm all is well. The first 30-45 minutes I opened "All" Apps then another 30-45 minutes with "All" Apps open and running a video. I was excited that the clean install via the Apple Techs of Maverick (wait 5 days) and then my install of Yosemite yesterday was a success. So I started checking email "searching for older emails to be exact" and bam! the fan kicked on temp went through the roof. I quickly "quit" email waited 30 seconds and reopened email as I snapped screen shots. Email maybe the problem... Back to the Apple Store for me...

I am having the exact same problem on my Macbook Air (mid 2012). It seems that after using the computer for a while. All I have been using is Safari or Chrome (been switching to test) and iMessage. Sometimes I have Skype or one of the Adobe program on. After 10 min the fan will kick in and start overheating. It is stating I am using 3.88 GB memory out of the 4 GB I have. This was not an issue in Maverick. I found a forum online in which a user reports having fixed the issue however, I don't fully understand what he did to solve it. Any ideas?

See post for Mail Memory Leak. I'm testing it now.

Thanks mlwebber & etresoft. I think we were able to narrow down the 4 most effective methods of temporarily resolving this issue it seems. I only had to disable the drafts to get back to normal, but others are reporting that using that in conjunction with a combination of 3 of the other methods from mlwebber are resolving their issues. Albeit this is only a temp fix until Apple updates their software & truly fixes this bug/issue, but, at least, I hope, we all can get back to business as normal for the time being.


Doren (from etresoft’s observations):

- Preferences/Accounts/Mailbox Behaviors: UNCHECK “Store draft messages on the server”


mlwebber:

- Preferences/Accounts/Advanced: UNCHECK “Use IDLE command if the server supports it”

- Preferences/General/Check for new messages: “Every 5 minutes”

- Preferences/Junk Mail: UNCHECK “Enable junk mail filtering”


Please post in this discussion if none of these methods help you and we'll see what we can do. We'd also love to know if these methods also resolve your issue. Thank you.

I did not want to wait any longer to get this fixed, so I installed Macs Fans Control - http://www.crystalidea.com/download


Fan for ODD is changed to base on Optical Drive and lowered a few degrees of max and min ( start earlier and fan more earlier )

Fan for HDD is based on recomendations from manufacturer, and lowered a few degrees as above.

Fan for CPU os based on Core 0 and lowered a few degrees as above.


This lowered the temp on my secondary heatsink with about 20 degrees! (Probably more)


And this was on my Late 2009 iMac 27" with i5 cpu.

Same problem here on a 2011 Macbook Pro Retina.


I fixed the problem by removing my user launch agents (a type of background process):


I had 3 launch agents:


com.google.keystone.agent.plist

com.apple.serveralertproxy.plist

org.virtualbox.vboxwebsrv.plist



I removed them in Terminal like so:



cd /Users/petec

mkdir LaunchAgents(disabled)

mv LaunchAgents/* LaunchAgents(disabled)



This will disable them but keep a copy. If you want to enable it again, just move it back in place.

I was having the same problem and noticed it after updating to Yosemite. I've always ran the smcFanControl app to keep my Macbook cool. I know a few have their opinion about the fan control apps where you can control the fan of your computer. It has always worked for me. Especially using it during leisure time when the computer is in my lap (when it seems to run hotter) versus my desk at work. But since the update, the smcFanControl has been useless and the computer has been WAY hot!!


Good news! SmcFanControl finally decided to update their app and the result is a much, much cooler computer. So you may check out the smcFanControl app, it may work for you. It seems to be finally working better with Yosemite


Hope this helps.

Pete, you solved my problem too. I updated to Yosemite a couple of weeks ago, and since then my late 2011 MacBook Pro's CPU has been running at around 90-95 degrees, and the OS was automatically restarting two or three times a day. I tried disabling background processes (dropbox, iKey, menuclip, bettertouchtool, etc.), tried disconnecting my external monitor, but nothing worked. Sometimes it seemed as if I could work for longer stretches with out a restart, but the fans would kick in a few minutes after logging in, and sooner or later the Mac would reboot.


I downloaded and ran LaunchControl, which showed me two User Agents with problems (see screen shot below). I unloaded both of them, and have been running for about 48 hours without a single problem. CPU temperature is around 55-60 degrees, and the fans have been idle all the time.
