If you are upgrading from Mac OS 9 to Mac OS X 10.2 or Mac OS X 10.3 on a computer that otherwise meets the system requirements, make sure that the computer's firmware has been updated. This list shows which firmware updates are available and appropriate for each computer.

As explained in document 51764 "Mac OS X 10.2 Welcome and Install Manuals" and document 50071 "Mac OS X Welcome and Install Manuals", you may need to update the firmware on your Macintosh computer prior to installing Mac OS X 10.2 or 10.3. The following table lists the firmware updates that are available for Apple products that can update to Mac OS X 10.2 and 10.3. Note: Rows in PINK indicate computers that can install Mac OS X 10.2 but are not supported with Mac OS X 10.3.

If you are unsure whether your computer needs a particular update, simply download and open the update installer. If the update is already installed or not needed, the installer will alert you to this.

Important: These firmware updates cannot be installed when the computer is started up from Mac OS X. In order to install them, you must start up the computer from a Mac OS 8 or Mac OS 9 System Folder on the computer's hard disk (not from a CD). See the hardware and software requirements listed for each installer for details.
