LSD, I've just read through all of that. I haven't fooled around with a MAC since my Apple //e...........does that date me.
I did not see any mention of using SetiDriver, so I guess that's out.
It appears the "best" route is to use a "RAM Disk" and then load some prepared scripts as indicated on
this page.
The best I can do for Andy, for his at home MAC, is direct him to the above link and hope he understands what the instructions are and can follow them.
