Upgrading your OS - OS X Mavericks (10.9)


Disclaimer: Before you upgrade your system to OS X Mavericks (10.9), please be aware that not all of the software used at the University of Oklahoma has been tested with 10.9 and that users who upgrade their systems may experience issues.

Current known incompatibilities / issues: After some upgrade installations, Bootcamp is unable to load or run from Windows partitions. For this reason, if you decide to proceed with the update on a machine with a Windows Boot Camp install, we strongly suggest performing a backup of your Windows files first.

Also, for OU VPN users, your installed connection may not work until your Java client is updated.

Installation guide:

  1. OS X Mavericks (10.9) is a free update for Apple users which is compatible with the systems below. To get details about your Mac model, click the Apple icon at the top left of your screen, choose About This Mac, then choose More Info. Only the systems below are compatible with the upgrade.
    • iMac (Mid 2007 or newer)
    • MacBook (Late 2008 Aluminum, or Early 2009 or newer)
    • MacBook Pro (Mid/Late 2007 or newer)
    • MacBook Air (Late 2008 or newer)
    • Mac mini (Early 2009 or newer)
    • Mac Pro (Early 2008 or newer)
    • Xserve (Early 2009)
  2. Also note that while the above computers can install Mavericks, some features, such as Power Nap, AirPlay mirroring and extended desktop, and AirDrop, have stricter requirements. Also Apple recommends the computer have at least 2 Gb of system RAM (memory), but the system may function better with additional RAM. 8 Gb of available hard drive space is also required. Please see this page for additional system requirements information.
  3. While the About This Mac window is open, check the current version of OS X the system is running. The version number will be listed beneath the serial number. It is possible to upgrade to OS X Mavericks from Snow Leopard (10.6.8), Lion (10.7), or Mountain Lion (10.8).

    • If the system is running Snow Leopard (10.6.x), update to the latest version of Snow Leopard before you download OS X Mavericks from the Mac App Store. Click the Apple icon and choose Software Update to install OS X Snow Leopard 10.6.8, the latest version.
    • If you’re running Leopard and would like to upgrade to OS X Mavericks, first you will need to upgrade to OS X Snow Leopard. It is available for purchase here
  4. To begin the upgrade, from the top left corner, click the Apple menu, then click Software Update... – If prompted, enter an admin name and password.
  5. The App Store opens and displays any software updates available for OS X and Mac App Store apps. OS X updates will be at the top of the list.
    • Click Update All to install all available software updates. If prompted, enter an admin name and password then Apple ID and password.
    • Click Update to install individual software updates. If prompted, enter an admin name and password then Apple ID and password.
  6. Once you have downloaded any system updates, click under Featured to see OS X Mavericks. Click to Install and it will download the installation file.
  7. The OS X Mavericks upgrade file is approximately 5.3 Gb in size. Once it is downloaded to your Applications folder, double-click on the file to begin the upgrade process and then follow the on-screen prompts.
  8. Next in the window that opens, click Continue, and then click Agree twice to agree to the Mavericks software license.
  9. On the next screen, choose where to install Mavericks. By default, only the internal startup drive is listed; if other drives are connected and you wish to install Mavericks onto one of them, click the Show All Disks button and then choose the desired drive.
  10. Click Install, and then provide an admin name and password when prompted.
  11. The installer will then prepare for installation. Next, a message will alert that the computer will restart automatically. At this point save any open work and restart the computer. If one does not restart the computer, once the preparation phase is finished, a 30-second warning will begin, and the Mac will restart automatically.
  12. After the Mac restarts, the installation will begin. This process can take anywhere from 20-100 minutes, depending on the Mac.
  13. When the installation finishes, the Mac will automatically restart to complete the installation process. Upon finishing the upgrade, the Mac will then boot into Mavericks.
  14. Upon loading the new OS X Mavericks 10.9 system, you will be prompted to enter system setup information, including such things as your Apple ID or iCloud login information. You will also be presented with a list of incompatible software, please see this Apple knowledge base article for more.
  15. Finally run Software Update again to install any additional system updates.
  16. If you need any additional assistance with the installation process, please call our help line at 325-HELP (4357).
