I have constant crashes with DT 2.9.4 on macOS 12 GM.
After 4-6- mouse clicks DT quits unexpected, always.
My database is 47.75 GB.
Would sending a crashlog be helpful?
Sierra is still a beta. Could you please choose Help > Report Bug (after pressing the Alt modifier key) and send the email to cgrunenberg - at - devon-technologies.com? Thanks!
