Using Mac OS Ventura 13.0 I have an extension in the general extensions section named “Tailscale” with a type of “Network” but in the sharing extensions section it does not appear and there is no tailscale on right click for any finder items.
Confirmed that we have enabled Taildrop in the admin portal
This is due to the way macOS Ventura handles system extensions - they need to be activated after being added. Go to System Settings > Privacy & Security > Extensions > Added Extensions and then check Sharing under Tailscale. Then go back to Extensions > Sharing and check Tailscale.
