Hi.

Yes, I can create and save .3dm files. Also, I can open them using Command O and by dropping the file on the app icon in the dock. Double clicking does not work; I get the dialog in pic 1 (attached). Only v3 Beta is in the Applications folder.

Some .ai files open normally - Comm O and dropping on icon - and others have "Invalid Name" dialog (pic 2). No luck with .pdf. When I try to open the original 8 files sent in the first post, the "invalid Name" popped up with the file I tried.
