I just downloaded 3.5. I have both Windows and Mac versions. The Windows version is fine, but the Mac version crashes upon opening when it loads, "Starting Audio Engine."

Now, here's the thing. I have an Echo Audiofire 4 FW interface for my MacBook Pro, and when that's plugged in, 3.5 is able to open. But most of the time, especially when I'm traveling/on the go, I'll just use the Mac's headphone output for audio, especially if I'm just sequencing VSTs or mixing audio that's already been recorded. So I assume it crashed when scanning the Built-In Output driver?

I've never had this issue with Studio One before.
