I use VNC (aka Screen Share) a lot, so I keep a folder of frequently accessed machines on my Dock.

The default VNC location file icon for OS X is a bit dull. Fortunately, OS X has a folder of system icons we can use instead. Even better, this folder contains icons for all recent Macbook, iMac and Mac Pro models.

The folder can be located here; hit ⌘⇧G in Finder and paste to jump right to it:

/System/Library/CoreServices/CoreTypes.bundle/Contents/Resources

Creating a VNC shortcut file

In order to access VNC locations from the Dock, we can create a .vncloc file. Use a text editor to paste the following into a file and save it with a name ending in .vncloc, e.g. user-hostname.vncloc:

<!DOCTYPE plist PUBLIC "-//Apple//DTD PLIST 1.0//EN" "http://www.apple.com/DTDs/PropertyList-1.0.dtd">
<plist version="1.0">
  <dict>
    <key>URL</key>
    <string>vnc://[email protected]</string>
  </dict>
</plist>

Note: you’ll need to change the vnc://[email protected] to the remote host’s details.

You can save this file wherever you like. I, for instance, keep all my VNC location shortcuts in a VNC Locations folder in Documents.

Changing the icon

First choose an icon from the folder above. These are .icns files, a wrapper format that contains the same icon in multiple image sizes. They should open in Preview by default; on the largest size hit ⌘A to select the image and ⌘C to copy it.

Next, with the .vncloc file we created above, right click and choose “Get info”. There is a small icon preview top-left; click to select it and hit ⌘V and it should paste the new icon. You can drag the location file to the right of your Dock for quick access.
