Currently, there is no Logitech Gaming Software for the Macintosh
platform, so there is no question of installation..its just plug n
play. It should function on a Macintosh computer running Mac OS 9x
with Input Sprockets 1.7 or higher and a functioning USB port. Make
sure your computer matches these specs.
To see if the device is detected, do the following:
- Click the "Apple Menu".
- Click "System Profiler".
- Click the "Devices and volumes" tab.
- Look at the USB tree to confirm that the controller is listed.
According to the Logitech website,
"If the device is not listed in the tree, it is not being detected. If
possible, try the controller on another system to confirm it is
working. If the controller works on another system, you will need to
contact Apple or the USB card manufacturer for assistance. If the
joystick fails on the test system, it may be defective. Exchange the
gaming device at the point of purchase if it is within 30 days of the
purchase date. If it has been more than 30 days since you purchased
your gaming device, please contact Logitech Customer Support to inquire
about an RMA (Return Merchandise Authorization) number."
