"using raspi-config, changed password, enabled vnc" this **ONLY** works for RealVNC (not sure what would happen if you use others).

"Ran vncserver :1" **Do not** just run `vncserver` 0r `tightvncserver`, although if you copied the script from https://raspberrypi.stackexchange.com/a/39374/8697 this **automatically** starts at boot, the whole point of the script.

Try running `open vnc://[email protected]:5901` on the Mac (changing to your IP) (Does NOT work with RealVNC - you have to use their custom viewer).
