Step-by-step Instructions

Please note that the file name you have downloaded may vary based on the version available at the time of download
  1. Get the Code42 Installer from the IS&T Software Grid. (Certificates required.)
    Result: The file containing the installer downloads as "Code42CrashPlan_Mac-MIT.dmg".

  2. Open the disk image file and find the installer named "Install Code42 CrashPlan.pkg".

  3. Double-click the "Install Code42 CrashPlan.pkg" package to start the installation.
    Result: The installer starts, and shows a Welcome window.
  4. Click Continue.
    Result: You are prompted to enter a Macintosh administrator username and password.
  5. Enter your Macintosh administrator username and password, and click Install Software.
    Result: Code42 will now install. A confirmation screen tells you that the installation was successful.
    At the same time, the Code42 program will start.

  6. Click Close to exit the Code42 installer.
  7.  Enter your MIT email address ( click Continue then authenticate with MIT Touchstone Authentication.

    1. You will have to choose whether the computer is setup as new device or to replace any existing device. The Code42 wizard will walk you through each scenario.

      Note: If you are asked for a server address or certificate, see CrashPlan (formerly Code42) is asking me for a server address and registration key
    2. You will now be at the Code42 Desktop main screen and your computer should begin to backup.
  • If you have many large files, first time backup may take a few days but subsequent backups should be quicker.
  • Code42 selects every "User" folder on your computer. It also selects some hidden folders; it is normal to see a half-dozen folders on the list, including ones that you haven't seen before.
  • Because Code42 is always working to keep your computer backed up, you may want to pause backups while you are away from campus to avoid using up your personal data limits or incurring any extra fees for overages. To pause Code42's backups, simply click the pause button next to the status bar per the image above. Just be sure to turn it back on later!
