If you attempt to install Apple Remote Access Personal Server version 3.0 onto a computer running Mac OS 8.6, a dialog box with the following message appears:
"the disk does not have Open Transport 1.1.1 or higher, which Apple Remote Access 3.0 Personal Server requires."
This will occur on computers running Mac OS 8.6 and Open Transport 2.5 or later. This combination was preinstalled on iMac (Slot Loading), iBook, and Power Macintosh G4 computers. ARA Personal Server version 3.0 is not supported on these computers.
To use Apple Remote Access Personal Server, you must upgrade to Mac OS 9, which includes Apple Remote Access Personal Server 3.5.
