How do I remove or disable AdobeIPCBroker?
This is what I had to do:


Kill Core Sync.
Kill CCLibrary.
Kill CCXProcess.
Kill AdobeIPCBroker.


I don't know if they'll come back the next time I reboot, but in an attempt to prevent that I also disabled the "Launch Agents" in com.adobe.AAM.Updater-1.0.plist and com.adobe.AdobeCreativeCloud.plist.

(Who in Adobe thought it was a good idea to spend CPU and battery life constantly just to check for updates or things to 'sync'? That's like kids going around trick or treating all year just to be sure they don't miss Halloween. There are smarter ways to schedule things.)
