Notes:

  1. Mac OS 8.6 is supported on this model only if it was included at the time of purchase.
  2. Performa equivalent models are also included. This would include all 5xxx, 6xxx (including 6100), 475 and 575 models.
  3. These computers are supported by the version of Mac OS included with the computer when it was purchased; retail copies of Mac OS with the same (or earlier) version number may not include the system software components necessary to start up these models. These computers are also supported by all subsequent versions of Mac OS.
  4. You cannot use the Mac OS 9.1 downloadable update with these computers. For more information, see article 106089: "Mac OS 9.1: Start Up from CD to Install on Original Power Macintosh Computers."
  5. If you are installing Mac OS 9.1 on a PowerBook 3400 running Mac OS 9.04, you must perform the installation without updating your hard disk drivers or your computer may stop responding during installation. To prevent the Installer from updating your hard disk drivers, click Options in the Install Software panel of the Mac OS 9.1 Installer and deselect the option to update your hard disk drivers.
  6. Password Security is not supported on PowerBook 1400s with Mac OS 9.1. If you have Password Security installed on a PowerBook 1400, you should turn off password protection before installing Mac OS 9.1.
  7. The parenthetical product descriptions (Summer 2000) and (Summer 2001) refer to the summer of the Northern Hemisphere.
  8. This computer originally shipped with Mac OS 9.2. The Mac OS 9.2.1 update is fully supported.
  9. Will start up only in Mac OS X, but most Mac OS 9 applications can be used with Apple's bundled "Classic" software environment. For more information, see article 86209, "Macintosh: Some Computers Only Start Up in Mac OS X".
  10. Will start up only in Mac OS X, as in note 9 above. Mac OS 9 is not pre-installed but can be installed (custom installation) from the discs that came with the computer. More...
