Mac OS X versions 10.0 or later requires one of the following Macintosh computers:

* Power Mac G4 or Macintosh Server G4 (all models)
* Power Macintosh G3 or Macintosh Server G3 (all models)
* iMac (all models)
* iBook (all models)
* PowerBook (all models later than the original PowerBook G3)

Notes
1. Identifying PowerBook computers: All PowerBook computers that work with Mac OS X have a large, white Apple logo on the outside of their display lids.

2. Computers with microprocessor upgrade cards do not work with Mac OS X. Though Mac OS X may install and appear to function normally on some computers with third-party microprocessor upgrade cards, Apple does not provide technical support or assistance for Mac OS X when used in this way. Contact the manufacturer of your microprocessor upgrade card for support information.

3. If your Power Macintosh G3 or Macintosh Server G3 computer has a build-to-order (BTO) 128-Bit 2D/3D Professional Graphics Accelerator Card should see article 106404 at < www.info.apple.com for more information.

Additionally, the computer should have:

* 128 MB RAM (memory)
* At least 1.5 GB free hard disk space
Note: For Mac OS X 10.2 or later, 3.0 GB is the recommended minimum. The exact amount required depends on your computer and how you install Mac OS X (default versus custom installation, for example).
* Mac OS 9.1 or later for Classic applications
