After a crash occurs, you can capture crash logs by running the CaptureLogs application (/Library/Application Support/Blackmagic Design/DaVinci Resolve/CaptureLogs.app). This saves a compressed file with the relevant logs.
You can send crash logs with details on how to reproduce to davincihelp (at) blackmagicdesign (dot) com.
Thanks Dwaine. I already have a few days back but no response yet. Would you suggest I resend?
On another subject wanted to recommend Side by Side the movie. Davinci hardware-software feature prominently in interviews with Stefan Sonnenfeld (Collateral, 300, Alice in Wonderland), Jill Bogdanowicz (J.Edgar, Gran Torino, Ray), Tim Stipan (The Wrestler, Black Swan, Che) and also in a short segment involving Roger Deakins in the DI session for 'O Brother Where Art Thou?'.
