When I open a few different applications, the temperature quickly surpasses 200 F, however, when I'm working lightly, it is around 170 F. It just seems like ever since I upgraded to Mavericks, it's heating up very often and fans go crazy, which is by design I guess.

I just don't know what this ouc process is and why it's using so much CPU. I force quit it, but it comes back in a few minutes again.

Given ouc is not a process that ships with Mac OS X it appears a third party product is causing the problem.

Searching the web suggests ouc is embedded within an application called "Mobile Partner.app".

If you have this application, please report the problem to the developers.

Manual Removal

It is always better to use the removal process provided by the developer; however, if Mobile Partner does not provide a removal tool, you might like to disable the ouc process manually.

You mention force quitting results in an immediate relaunching. This suggests the ouc process is managed by a launchd job ticket. launchd is a watchdog process that will monitor processes and relaunch any that run into trouble - such as crashing or being force quit.

Take a look in the following folders for a launchd job ticket associated with ouc:

  • ~/Library/LaunchAgents
  • ~/Library/LaunchDaemons
  • /Library/LaunchAgents
  • /Library/LaunchDaemons

The files in these folders are text files and can be read using TextEdit or a dedicated text editing tool, such as TextWrangler.

If you find a file mentioning ouc, move it out of the parent folder and restart.

As @oma mentions, if you can not find a launchd job ticket, look inside /Library/StartupItems for a folder or file containing ouc. Delete the ouc folder and restart.

    Cool thanks. It was indeed an app that I installed recently when I used wireless internet overseas. It was used in conjunction with the USB internet stick made by Huawei and service provided by mtel ISP. – zen Dec 13 '13 at 14:51
  • i had the runouc issue where 97% CPU was used for this process, on the activity monitor i just selected the process and hit quit, my battery life became normal and the service sign on the battery went off – user88481 Aug 22 '14 at 15:03
  • I also have a Huawei USB modem and this same overheating issue with runouc running on the activity monitor. I forced it to quit and everything went back to normal. – user90072 Sep 8 '14 at 19:44
  • I am also having the same problem and am also using a Huawei USB modem. I have forced the item to quit, but it still starts up again from time to time. I have now manually removed the file as directed above. Seems to be much better. Thanks for the tips – user96712 Oct 21 '14 at 1:46

    this didn't cut it for me. after long time (weeks) of this reoccuring, I found it here: /Library/StartupItems. Delete subfolder StartOuc. There are HW folders there too that I deleted. I'm staying away from Huawei from now on. – oma Feb 10 '15 at 13:18
