When I boot in safe mode, the computer does not seem to be overheating. Any other thoughts?

That usually suggests that a third party application is the offender. Anti-Virus software and so called 'cleaning' and performance applications are often the prime suspects. Delete all third part applications and reinstall them in a systematic order so that you can identify the 'problem child'.

Ciao.

I don't have any anti-virus or cleaning software installed... Could an app that's not even running cause an issue?

Temperatures are high. Post an image of both the temperatures and Activity Monitor as previously requested. I am done for the night and I will look in tomorrow morning if no one else assists you.

Ciao.

For the time being, forcing the fans to stay on "high" seems to be bringing down the CPU temperature a little bit. You can do that in the iStat menu, choose "Active set" and set the fan speed to High. Hope we figure this out soon!

I just tried making a new user on my mac and logging in and the issue completely went away. The CPU was no longer overheating and the fans stopped blowing at max speed. It is definitely some kind of app running in the background that is making the CPU go crazy. I will post back when I figure out what it is...

I just installed it Today and my fan started to work after one hour of working with it and temperature is too high.

Also, my battery life went from 99% to 30% in 3.5 hours just using Safari, Mail when before same work allow me around 5-6 hours of battery life with the same process.

Did you try shutting down your computer and then only log in to your new user? That's working for me so far but I'm still trying to figure out what is causing the issue. I have an apple Genius Bar appointment for Friday and I'll let you know if I figure this out... Good luck!

Alright so I got sick of my Macbook pro overheating and decided to format my HD, do a clean install of Yosemite and restore all my information from a time machine backup (except for computer settings, I decided not to import those in case the problem was coming from there). I did not expect this to work, but for some reason, my computer is no longer overheating. Everything is back to normal. This should definitely not be the only way to fix this issue and hopefully Apple will address this in the upcoming patch but it did work for me. Good luck!

I was having overheating problems on two different computers after upgrading to Yosemite. I finally solved it.

I was running a program that uses notification center to tell me when I have new gmail messages. As soon as I would get a notification, the computer started to heat up. I tracked down the problem by using Applications/Utilities/Activity Monitor and looking at the Energy tab. The mail notification program was having about 1000X more average energy impact than anything else. I shut down the app and the computer cooled off. Eventually, it was back to normal temperature. I installed another program that serves the same mail notification functions and it also had the same problem. I am assuming that some change in the way Yosemite handles notification center events was causing these apps to get into some kind of runaway condition that caused the CPU to overheat.

It's now been 24 hours since I removed these apps and everything is running cool as Mavericks. Hope this is helpful to people who come looking in this discussion for a solution.

Jakkov, I had the same problem; disabling two problematic User Launch Agents solved it for me. This blog post contains a helpful step-by-step solution.

Cheers.

Jakkov, you mentioned in your previous post that launchd is using a lot of memory, which certainly points to a Launch Agent problem. Have you checked for errors in other directories? I see you had one problem with your User Launch Agents, which you've correctly unloaded and disabled; maybe you should try the other options in the dropdown menu at the top left os LaunchControl (Global Agents, Global Daemons, etc.).

I know how frustrating the problem is, mate; it nearly drove me mad :-)

Cheers.
