I created a new file in Rhino but had not saved it yet. Then Rhino crashed.
Normally in this situation Rhino asks to restore the file when it is restarted.
This time nothing happened.
Is the work file saved anywhere?
But does where is the file before an explicit save?
Late reply but…
Check two spots. Your Autosave Information folder in your user library. To get there hold Option down when in the Go menu for Finder > Library > Autosave Information. Secondly, check your trash bin.
