Tuesday, June 11th The most serious problem happened to me since I use Rhino BETA. I was working on a file of about 1.5gb using snapshots. During the execution of the “_group” command, Rhino froze. It was not possible to save or close Rhino, forced closing was also not possible, not even a restart was possible because the system detected Rhino open. The only solution was to turn off the Mac.
