I am experiencing this same issue. I also have VMware Fusion installed and am wondering if there is some kind of conflict there.
I'm having the same problem. I uninstalled and installed appcatalyst again but the problem persisted. Mac OS X is 10.11.5.
vmware-vix-$PID.log has an error about some license check failing. Below the error messages and the license which came
with the installer.
% appcatalyst vmpower list

I have met the same issue, any update about this issue? I'm running macOS 10.12.
