I downloaded it correctly and it shows up in my DAW, but I can't open is since my Mac / DAW can't figure out who the developer / vendor is. is there a way to fix this?
Interesting, I can't reproduce your problem, it still works fine on my machine. If you're still having this issue, can you send an email to support@nimble.tools? I could probably send you a new build that might fix this problem, but would like to confirm that it does before I release it publicly.
