I'm using OS X El Capitan on iMac 21.5". As an experienced user, I follow activity monitor sometimes for security of my device. For 2-3 days,"ss_conn_service" is running on my device. I cannot determine what the process do. I suspect from a Galaxy Tab which I plugged to my device 2-3 days ago. Did you encountered with this process ?

Sample of the process obtained from Activity Monitor:

Analysis of sampling ss_conn_service (pid 62) every 1 millisecond Process: ss_conn_service [62] Path:
/Library/LaunchAgents/ss_conn_service Load Address: 0x100000000 Identifier: ss_conn_service Version: ??? Code Type:
X86-64 Parent Process: launchd [1]

Date/Time: 2015-11-20 15:09:20.236 +0200 Launch Time:

Thanks.

  • A Google search shows it to be the Samsung USB Driver for Mobile Phones. – user3439894 Nov 20 '15 at 13:30
  • Yes. However, search reports show only Windows driver information. Is there any drawback available for deleting this app from system ? – Berk B. Nov 20 '15 at 13:34
  • I would look at the .plist files in /Library/LaunchAgents to see the one that's loading "ss_conn_service" and see what the path to the "ss_conn_service" executable is. This might provide additional information to help determine the source. As to deleting it, if it is for your phone then if you don't plan on connecting your phone to the computer again then deleting it shouldn't hurt. – user3439894 Nov 20 '15 at 13:49
  • Welcome to Ask Different. I'm going to assume there is an implied question here "How can I tell what package installed X" - if you have another question, you could ask a follow on question or edit this one. – bmike Nov 20 '15 at 14:35

I delete it from /Library/LaunchAgents. Now, everything is going well. I don't encountered any problem right now. Thanks for answers.

Going into a general, here's how you analyze any arbitrary file is too broad for this site, but you can pretty easily determine if something is part of the core OS by searching for the file amongst the receipts:

Use a tool like Pacifist to check for the file in question as part of the system receipts:

As you get more used to checking on things, you can also use these tools to look at what a specific installer is going to do instead of just running it.

One last trick, you can also use tmutil compare if you have time machine to see what files changed between one interval and another. I would recommend doing this for small time periods when you don't think much is changing. Typically, thousands of files change each hour - so you'll need to get used to weeding out the "false" positives.
