Running Multiple UPBOX+'s from a Single iMac

Heya folks,
I’ve got 7 UPBOX+'s (the ones with the old V4 head inside), they’ve been happily running off PC desktop using windows 10.., I’ve been asked to refit to a pair of iMac desktops…
So far I’ve managed to get my 2 test box’s printing the same file from a single iMac, however when I try to load different files on to the 2 box’s they overwrite so the same file is shown on both printers…
The plan was to use a single iMac to run different jobs on up to 4 box’s at once, is that posssible?
At the same time I’ve had issues with the activation LKD files…
I’m running Apple M1chip, 16GB memory & Sonoma 14.4.1 and Up Sudio 2.4.0(554) & the TierTimeV2400.LKD
Any help would be appreciated. :slightly_smiling_face: :+1:
