My Rhino opened an autosave document, which I don’t care about. I’d like to close it and quit rhino. I get this dialog:

If I choose “Revert Changes,” it fails:

I am forced to save this document that I don’t want before it will let me quit.
Save in Mac will not work if you leave local network. If you keep file opened and join the same local network later you can’t save the file and you can’t close the file without saving. You can move the file to new location, but can’t save. Solution is to select all objects and export. Only way to close Rhino8 for Mac is then ForceQuit.
