Firstly great work on sharing of ability .. great minds

I'm a DMX newbie but somewhat determined muso keen to take advantage of the digital revolution ..
I've got an Enttec OpenDMX USB that has been operating with my iMac running QLC+ on Mac OSX 10.8.5 - brilliant


My problem is that having bought a s/h Macbook 2.1 immediately upgraded to Mac OSX 10.6.3, (seems QLC+ won't operate on earlier OS) to take to the gigs, QLC+ now refuses to 'see' the Enttec OpenDMX USB despite it being clearly visible in the USB Device Tree as outlined in Enttec's troubleshooting guide for Mac OS. - The only Enttec offering!
Exhaustive searches reveal 'fixes' for removing Mavericks' errant USB device drivers which I suspect is likely to be a similar problem to mine, and some 'terminal' patches and the like and not specifically suited to this problem, but being a 'coding' imbecile the search for such beasties is out of my league!
I also downloaded software updates, but ironically either the Airport Utility 5.6.1 or the Mac OS 10.6.8 update introduced major networking dilemmas that meant the Macbook would no longer connect wirelessly to my router! and still didn't see the Enttec

Hopefully someone has had (and fixed?) this experience? a fix? workaround? more of a clue than I!

Thanks in advance and again to all contributors .. a truly wondrous resource

Cheers
