This is a bit different than with a Windows PC, but it’s not hard. Let’s say your ‘S’ drive is on “\\utmbfs3\elbows$” in Windows-speak (that’s a fictional address, for this example only). To access it via OS X (after you are connected to UTMB via VPN), go to the Finder (click the desktop) and select the ‘Go’ menu, then ‘Connect to Server…’ (or just hit CMD-K on the keyboard). Type in “smb://utmbfs3.utmb.edu/elbows$” and click ‘OK.’
You will be asked for credentials. Type in ‘utmb-users-m\yourusername’ and your current UTMB password. If you are sure of the address, click the + button to add the address to your server favorites. Click OK, and the server will open in a new Finder window. You can set things so that servers get mounted automatically, if your Mac is always on the UTMB network:
Once the server is mounted, go to the Finder. Open ‘Apple Menu/System Preferences/Accounts,’ and click the ‘Login Items’ button near the middle of the window. Go to the Desktop and drag the server icon over into the ‘Login Items’ window, or click the ‘+’ sign near the bottom of the window to add the server by browsing to it.
