Hi
Thanks for your reply.
1. Enabld Remote Management --> Enabled VNC and provided full permission.
2. I have used Tight VNC Client -> Asking Password and accepting Password. After the TightVNC windows was black screen.
3. Tried with same network
How to Launch the VNC client using the command Line?
Regards,
Martin
How have you set up Sharing on your Mini? Is Remote Login enabled or disabled since this will affect whether you need to create an SSH tunnel first. Did you set a VNC password? Did you select "Screen Sharing" or "Remote Management"?
What commands are you using to initiate the VNC sesssion? Did you provide a user name?
Try modifying the Mini's Energy Saver settings to not put the Mac to sleep and prevent the hard drive/SSD from sleeping.
Are the Macs on the same network or are you trying to connect to another Mac across the Internet? If across the Internet, then the router/firewall for the remote network may need to be configured to allow access using port forwarding or a VPN connection to the remote network. Can you ping the remote Mac? If not,then you won't be able to connect with VNC.
Launch the VNC client using the command line so you can see or enable viewing verbose mode to get more information about the attempt to connect to the remote Mac.
Try rebooting the remote Mac.
Is "Remote Login" enabled or disabled?
I actually was having trouble connecting to a Mac using VNC myself. I had to try multiple times before I was able to connect. After disconnecting from the VNC session I was unable to access the remote Mac via VNC for a while. When I was having trouble I was able to enter my VNC password, but a VNC window never opened. Even when I connected to the remote Mac the graphics in the session were very slow to load and both computers are on the same LAN. I don't have these issues when connecting to a Linux remote system. Plus different versions of macOS seem to behave differently.
On Linux I use the following command to connect to a Mac using VNC (xtightvncviewer is being used -- I believe you can just use the tightvncviewer command as well):
vncviewer <ip-address-DNS-name-of-remote-Mac>
or
vncviewer <ip-address-DNS-name-of-remote-Mac>:5900
On the Mac I have enabled a VNC password (click on "Computer Settings" button under Remote Management). I have also enabled "Observe" & "Control" found on the "Options" button for the authorized user. When using the command line I am prompted for the Mac's VNC password before it launches a window for the remote GUI session.
If Remote Login is enabled, then you may first need to establish an SSH tunnel before being able to connect using VNC.
I don't recall if I ever was able to enable a logging session (If I did I don't recall how I enabled logging the connection attempt).
Do you have any security software running on either computer that may be interfering?
Mac mini VNC connection is black screen.
