How do I delete a process that's running in the background?

Question

How do I delete a process that's running in the background?

A process called "tunmgr" is using up 99% of my cpu causing my macbook air to overheat (and the fan(?) to be really loud). I've searched about the process/file and a few websites basically just says that it is a Blackberry app(?) and that it hasn't been confirmed (yet) to be harmful.

I've already deleted the blackberry desktop manager on my computer as I've recently switched to iPhone. Is it safe for me to delete "tunmgr" and how do I do that?

Every time I notice my computer overheating, I had to keep going to Activity Monitor to force quit the process/file.

I've been trying to do this for years - thank you for figuring out the answer - questions about this wretched application are all over the web but you are the first to nail the issue down to the Application Support directory as far as I know- thank you!

I have this problem too, where the Blackberry-Link-Helper-Agent is using 57% of my CPU. I deleted the Blackberry software ages back, and don't have anything else RIM-related on my iMac. I don't have the "tunmgr" process, fortunately.

I've tried finding it via Terminal, but that utility is responding "No such file or directory". Do I need to download and install the Blackberry app again, then uninstall to get rid of this thing?? Anyone else still having this issue?

If you know that this process was started by the Blackberry software, and you've removed the software, reboot to get rid of it.

Sorry I didn't get the chance to update this.. I had to delete through the terminal.. the path is library/application support/Blackberry(?).. i just deleted the whole folder/directory.. then I restared my computer and haven't had problems since..

I'm sure it's the same path for everyone, but if not, go to activity monitor, click tunmgr then on the top left, click "sample process".. you'll find the path.. then go to terminal and just follow the path then you can delete the folder/directory..

hope this helps

Solution as stated above.

when deleting apps good idea to trace down all related files that were installed.

A simple App removal tool can help like Appzapper or anyone of those.

Likewise good habit of removing any associated Application support files that are related to the app you are removing.

Don't need Terminal for 3rd party/user installed Apps most eof the time.

I have the same problem... seems to be a bug.. if you installed BlackBerry Link and haven't logged into your blackberry account yet, the tunmgr goes into a loop. Once I signed on successfully, the high CPU situation goes away.

Hi, I tried the above solution but the below two processes still keep coming up, also unable to delete Blackberry Link from Applicataion Support folder. Each time I delete the file, it comes right back!

BBLaunchAgen.app and Blackberry-Link-Helper-Agent

Any further support will be appreciated as these are really taking up a lot of CPU...thanks.

(Just to add; tunmgr is succefully deleted)

I had the same problem and researched it. The tunmgr is essentially a bug that spawns a looped process due to checking the "Open Blackberry Link when a device is connected" in Blackberry Link. To stop the process, open Blackberry Link -->> Preferences (not in the main menu, the gear in the top right corner) -->> uncheck "Open Blackberry Link when a device is connected". Then restart and it should be back to normal.

ps - thanks for fixing this Blackberry!
