I just spent an awful amount of time trying to uninstall Kite.
There were two background processes: Kite Helper and Kite Engine Which showed up on Activity Monitor,and I could never get them to quit, each time I killed a process with the PID, a zombie would spawn up with a different PID.
Eventually I killed them both by removing the Kite packages from the Cache in library, emptying the trash and then restarting my machine.Phew!
Not to mention the slow autocomplete suggestions in Sublime Text 3. I think I'll just stick with my old setup.
