System Requirements
OS X Requirements
OS X V 10.2.1 or later is required. We recommend updating to the latest
release available.
Devices can be connected by either SCSI or FireWire. Please note that if
you are connecting a SCSI device through a SCSI to FireWire device it will
be represented as a FireWire device - that is the bus number in the device
window will be 9.
To be recognized by OS X, devices connected to a standard SCSI adapter
must be present when booting the Mac.
A SCSI device connected via a SCSI to FireWire adapter will be recognized
when the adapter is plugged in.
The SCSI device itself must be turned on before connecting the adapter to
FireWire or rebooting.
