Hello
We don't officialy support 10.7 neither 32bit on all mac os versions, but we tested it, and it works.
We provide a commodity compatibility with it,
Known issues are related to the use of 32 bit live and logic mostly.
As we moved toward morecent OS and tools versions their is a risk we can't maintain it.
You can test that it works by installing the demo versions.
Just go on arturia.com/downloads and install without activating any of our softwares to test it for free.
Warning: the sound stops after ~20mn, and you can't save presets with this demo versions.
Best
