I don’t know about you but I think the Adobe Creative Cloud auto-launch is really annoying. The thing is, I haven’t been able to find a way to toggle it in the OS X’s user login options so I scoured the web and found a solution! [Link]
It is loaded by default by /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist.
If you run
launchctl unload -w /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
that will disable it for your user.
To turn it back on
launchctl load -w /Library/LaunchAgents/com.adobe.AdobeCreativeCloud.plist
