Printing from a Macintosh desktop or laptop to a CSE printer now requires authentication prior to printing. At present, we offer only one printing method. Authenticate with your Kerberos (CSENetID) credentials. Can be used with wireless and wired connections. Setup for wireless and wired connections differ slightly.

Before You Start: Kerberos Tickets

With Kerberos printing, you must have a valid Kerberos ticket before printing, which you can access through the "Ticket Viewer" application located at "/System/Library/CoreServices/Ticket Viewer" on your Macintosh: in a new Finder window, right-click the folder name/icon, and select "Macintosh HD" (or whatever your system disk is named), then navigate to System > Library > CoreServices and double-click the "Ticket Viewer" application icon.

If you do not yet have an "identity" in the "Ticket Viewer" application, you'll need to create one.

  1. Select the "Add Identity" button. A new window appears.
  2. In the "Identity:" field, type "username@CS.WASHINGTON.EDU" replacing "username" with your CSE account name. The "CS.WASHINGTON.EDU" part must be capitalized.
  3. In the "Password:" field, type your Kerberos password.
  4. If you'd like, you can select the "Remember password in my keychain" checkbox.

If you have an identity with your CSE Kerberos principal in the "Ticket Viewer" application, and it says "No ticket," you can renew it by selecting the "Renew" button (circular arrow) and entering your Kerberos password. If you successfully entered your password, you'll see the new expiration time of the Kerberos ticket.

One can also use the "kinit" command in a terminal window to establish or renew one's Kerberos credentials, by typing "kinit username@CS.WASHINGTON.EDU". (The capitalization of "CS.WASHINGTON.EDU" is intentional and required here.) The "klist" command shows the status of one's Kerberos credentials.

Kerberos tickets do expire (a) after ten hours, (b) when you log out, or (c) when you reboot your Macintosh. If your print job is "held for authentication," please make sure you have a valid Kerberos ticket, which you can do in the "Ticket Viewer" application, or from the command line.

Before You Start: Setting Up The Preference Pane

If you haven't set up a CSE printer on your Macintosh before, there's one task you must accomplish: the "Printers and Scanners" System Preference pane needs the "Advanced" icon (it looks like a gear) available for you to use. Follow this sequence of instructions to make it happen:

  1. Open the "System Preferences" application, and select "Printers and Scanners."
  2. Select the "+" icon at the bottom of the "Printers" list on the left side of this pane. The "Add" window appears.
  3. Right-click just to the left of the "Search" box, and select "Customize Toolbar." An empty box appears in the toolbar (near where you just right-clicked).
  4. Drag the "Advanced" icon - the gear - from the list of "...favorite items..." into that empty box, and select "Done."

Remote Access

Connection to a Linux Host

Use the Macintosh "Terminal" application, and use the "ssh" command with your Kerberos credentials:

ssh -Y
The "-Y" ensures X11-forwarding; with the proper X11 software installed on your Macintosh - see this resource - you can redirect the GUI from a Linux program to your Macintosh.

Connection to a Windows Host

The "Husky OnNet" VPN service is now required for connection to on-campus resources, when connecting from off-campus locations. Detailed information about this service can be found on the UW IT Connect pages, or you may choose to proceed directly to the Husky OnNet download page. (Accessing this link requires UWNetID authentication.)

To install the software, download and unpack the "ZIP" file, and run the "mac_edgesvn.pkg" installer.

To use the software, start the "BIG-IP Edge Client" program, found in your Applications folder, and authenticate with your UWNetID credentials. Once connected, you can use Microsoft Remote Desktop (see below) to connect to on-campus resources, with no additional gateway configuration necessary.

Use the Microsoft Remote Desktop Connection application, available for free from the App Store. Please note, the version of RDC that comes with Office 2011 is obsolete; the version available from the App Store includes modern encryption protocols necessary for connecting to our Windows resources. Use your CSENETID credentials.

Network File Access

There are several ways of accessing networked file shares on your Macintosh. These methods assume that your Macintosh is connected to the department's network; i.e., you're not working from home or some remote location.

Mounting a Remote Directory with "Samba"

Your departmental home directory, or project directory, can be mounted temporarily or permanently on your Macintosh via Samba, by following these directions.

Mounting a Remote Directory with "sshfs"

  • Install the OSXFUSE and SSHFS packages from
  • Open the "Terminal" application.
  • Create the mountpoint: mkdir MOUNTPOINT. ("csehome" is a good example.)
  • Mount the remote directory by typing the following command all on one line:
    sshfs -p 22 username@host:/path/to/remote/directory MOUNTPOINT -oauto_cache,reconnect,defer_permissions,negative_vncache,volname=MOUNTPOINT
  • You'll be asked for your password - this would be your Kerberos password.
  • MOUNTPOINT is now the mount point for that remote directory.


If you've been issued a Macintosh laptop, by the department or your research group, we strongly recommend that you take the steps necessary to enable the "Find My Mac" service. There's an Apple Support document which goes into great detail on this topic, but the "quick start" overview is:

  1. On your Mac, choose Apple menu > System Preferences, then click iCloud.
  2. If you're asked to sign in, enter your Apple ID, or if you don't have one, click Create new Apple ID, then follow the instructions.
  3. If "Find My Mac" is turned off, select it to turn it on.

If / when you need to find your Mac, you can sign into iCloud from another Mac, or use the iPhone app (available from the App Store).

It bears repeating: a good backup is always a good thing.
