Hello all,
NOTE: I write this post because in the download page says that v1.x.x is “still” compatible with 10.7+
Well, i had to downgrade one of my Macs to MacOS 10.7.3, because i have a wonderful M-Audio Firewire Solo that works like a charm, that i can’t not use with newer systems just because M-Audio stoped upgrading the driver at MacOS 10.7.4 (I really hate Apple polices! 
), and i don’t want to buy a new audio interface having one already that works just fine.
Anyway, this post is to say that i can’t run VCV Rack 1.x.x (even not the latest 1.1.2) in this system because it crashes right after i click it’s icon to make it run.
Here’s the relevant part of “log.txt”
