Hi Keith
I was gobsmacked to see on the M2 Tech site that there are no Young drivers for OSX before ''Snow Leopard" and " Lion".
Snow Leopard came out as late as 2009, and the above two operating systems are ONLY available on the very latest generation of Macs - which have the swappable Windows/Mac startup.
Any MAC produced prior to the 2009 Intel chips (we're talking about 25 years of Mac computers here!) simply cannot run "Snow Leopard" or " Lion".
I know you use a Mac yourself. With the common use of Mac's for music and media, it is amazing to find (what appears to be) extremely limited drivers.
