I have a 2005 Mac Mini & iMac, both using iOS 10.5. I can't find my monitor adapter to hook the mini up to the ViewSonic monitor I used to use with it and I was wondering if I can just get it to show up on the desktop of the iMac as an external drive. I've hooked it up by usb and firewire but it's not showing on the desktop. Am I doing something wrong or is it just not going to work? I've been on Macs since 1988 but I've never used more than one at a time and never as an external HD (though I have had lots of those, they were just external HDs). Any help would be very appreciated! Thank you!!
