Hey folks - having a bit of a puzzle over something. I have a QMK macro pad (BDN9) set up, but MscOS doesn’t see it at all. I tried USB Overdrive, which seems to have made some difference - now the pro micro’s LED is on - but still nothing.
Any tips or basic things I’m missing?
Something similar happened to me when I got a new macropad. Try:
-Updating/reinstalling qmk
-Flash it to default again
My problem was qmk needed to be updated.
I have a mac for work and I’ve used a lot of keyboards/macropads/etc with qmk with it and I’ve never had any issues at all
Thanks for the suggestions, guys - I almost wonder if I grabbed a bad cable; will have to try again tomorrow.
It was the cables. 
Both the one I had with me and the one I borrowed were not quite right. Works perfectly now.
