Yosemite high CPU usage by "launchd"

Hello,


My MacBook Pro Mid 2012 has been having this issue of launchd just using up 85% of my memory and I can't figure out what the problem is that is causing this. It is starting to get annoying now because my battery is dying faster than ever, and quickly overheating.


Can anyone guide me or help solve this issue?

MacBook Pro, OS X Yosemite (10.10)

I had this issue for several weeks with my mid-2012 MBA after installing Yosemite. Just like with you, this showed me that "launchd" was the culprit . I talked to some tech friends who explained that launchd is a little program that automatically launches other apps, sometimes in the background, for various reasons. Up until last week, my solution was to reboot the machine anytime it got hot (several times a day). It was a huge pain, and I was borderline ready to give on on Apple having still not seen any official response to this issue that seems to be plaguing many users. Here's step-by-step what I did to resolve it.


1. Open Activity Monitor by typing "Activity Monitor" in the spotlight search. This confirmed launchd was the memory hog

2. Open a Finder window and type select from the menu: Go > Go To Folder (or simultaneously press CMD+SHIFT+G keys)

3. At the prompt, type "/var/log" to access the machine's folder that contains the log files

4. Sort the folder by "Date Modified" and look for the most latest file called "system.log"

5. Double click the file to open it in the Console app

6. Scroll all the way down and see if any lines contain "error," especially repeated lines going back as far as when you noticed the machine was hot.


For me, the culprit was Adobe Pro 9. Apparently this program would try to update itself after I upgraded to Yosemite, but the install update application wouldn't run correctly in Yosemite, so lanchd would try over and over and over again to launch the install application, getting stuck in an infinite, very hot, loop. I deleted Adobe Pro 9, and now everything is back to normal. I don't need Adobe Pro any more, but if I did, I would just get a new version that is compatible with Yosemite.


I hope this helps,

Omar

I'm also having the problem. Running hot and launchd taking up 90%+ of the CPU. I ran the system log and it's obviously trying to run something a thousand times a minute. Any idea what it is?


Feb 18 19:16:26 Chases-MacBook-Pro-3 com.apple.xpc.launchd[1] (com.WebTools.oiuqw343sQ9a[72883]): Service setup event to handle failure and will not launch until it fires.


Any help would be greatly appreciated!

Hey Omar,


Thanks for this post, I am having exactly the same issue, but I cant figure out the application causing the problem, I get the following in the system.log..


May 22 08:47:02 Zacharys-MacBook-Pro com.apple.xpc.launchd[1] (/var/root/Library/betulinic/betulinic[45396]): Service setup event to handle failure and will not launch until it fires.

Thank you for this recommendation. I had the same issue and it the launchd process was always around of 60-70% of CPU time and was killing the overall performance. I tried the download recommended for the malware but that did not work. I did as you suggested. Moved all my files in /library/LaunchAgents and /library/LaunchDaemons to a sub directory in those folders. Rebooted and all was fine. launchd was below 2%. One by one (including the Adobe files) added them back. All but one was the culprit, left it out, rebooted and we good to go. Thanks again for the recommendation.

I am using Thunderbird version 31.2. I updated to 31.3 and it dint work very well so I reverted to 31.2

Now I am getting high CPU 100% all the time using Thunderbird. According to Activity Monitor its Launchd1 causing the issues

I apologise but I don't follow the below threads as to what I can do about it. I have apple support but they probably will not help me as they don't support third party software. Any easy fixes anyone can suggest are welcome.


Thanks and Regards

Mike
