If you have network access on campus, go to the menubar>Go>Connect to Server, (or press command and K) to go to the server.
Type gcserver in the address space. Click the + to add it to the list.
Click “Registered User” for the user type guest and the password type guest, then you will see a list of shares to access. Normally you would access the share related to your class.
If you are off campus, you will need to use the VPN client from download.clemson.edu. Download it, install it, and you can reach the gcserver the same way as above from off campus.
