Upgrading Your Mac to OS X

If you're interested in upgrading your current Macintosh to Mac OS X Leopard 10.5, you should make sure that your system meets all the necessary hardware and software requirements to ensure a smooth upgrade. Here's what you should do:

  1. Confirm that your hardware can run Mac OS X 10.5
    Mac OS X 10.5 requires at least 512MB of physical RAM, a DVD drive for installation, and an Intel, PowerPC G5, or PowerPC G4 (867MHz or faster) processor. To verify that your hardware can run Leopard, see the list below or http://www.apple.com/macosx/techspecs/.

  2. Verify you have enough hard drive space
    While the amount of disk space required depends on your computer and the way you are installing Mac OS X, you must have at least 9.0 GB of available space on your hard drive.

  3. Check out third party hardware and software compatibility:

    Third Party Hardware Mac OS X includes out-of-the-box functionality for many hardware devices. However, some devices may need additional driver support from the manufacturer. Please check with the manufacturer of your product to see if Mac OS X-compatible drivers are available.

    Third Party Software The Classic environment and the applications that use it are no longer supported. Some third party software may also need updates or upgrades from the manufacturer to function properly. Please check with the manufacturer of your product to see if Mac OS X 10.5 is compatible
