I have a legit copy, and it was my favourite DAW, still is to a certain extent. However, I made my last tune completely in Ableton and it was so smooth and didn't crash once, I've gone back to finish an older track in Cubase and it's crashed on me a few times this morning already. I wish it would just throw up an error instead of totally bringing down the DAW if it's a plugin problem. Would that be ridiculously hard for them to implement? I don't know. Anyway, bit of a rant. I just make sure I save every ten seconds. What's other people's experiences with their DAW's stability on their macs?
