Just a line to help if ever you need to VNC onto a OSX Mac. There’s a little gotcha at the end stage if you’re not careful.
Enable VNC on OSX
OSX 10.4 and above as far as I’m aware has VNC built in – you just need to find where it is to turn it on. I have access to 10.4.11 but in later version the process is the same it’s just the windows that change about a little.
1. From System Preferences choose Sharing.
2. Now enable Apple Remote Desktop and while you’re here also turn on Remote Login as this will enable you to carry out a SSH (Secure Shell) connection to the system if you need to.
3. Choose “Access Privileges” to enable the VNC control option and set a password for VNC control of the Mac.
Your Mac is now ready for VNC control.
VNC PC setup
Sadly you just can’t launch VNC in its default state to control your Mac.
Launch VNC (Used here was Real VNC 4.1) and then in the options make sure you set the colours to Full else if you leave the default of Very Low the Mac will not connect!!
If all else fails and you can’t VNC into the system then perhaps a restart of the system is needed. If you need to this remotely from a PC then use Putty to establish a SSH connection to the Mac. Log on as an appropriate user with the correct password etc
Once logged on you can use the following command to restart the Mac
sudo shutdown –r now
the –r makes the system reboot rather than shutdown.
You’re asked for the admin password again after using the shutdown command, once you enter it correctly it will reboot
