Quick tip: if you’re getting errors (e.g. instant disconnect or won’t connect) when connecting to your mac through VNC, try the following:
- Be sure to specify a password under "computer settings" on your mac.
- Set the "color level" to full (all available colors) on your VNC client. In RealVNC, these can be found by clicking on the options button.
