OSX native applications

No USB driver is required for the DTP92 USB under OSX 10.2.

Classic mode under OSX

The DTP92 works properly in "Classic Mode" (OS 9.1) with the USB version of the Monitor Optimizer attached, as long as the proper driver is installed in the OS9 system folder.

Note: The serial versions of Monitor Optimizer and the DTP22 will work in Classic mode using a Keyspan adapter.

Workaround: You can still run the Monitor Optimizer system if you boot from 9.1. This profile can then be used in either the Classic environment, or if copied to the Library/ColorSync/Profiles folder in any OSX native applications.
