I used a shared 'SD' folder on the microSD card of my BlueSCSI V2 to copy old Macintosh Plus compatible files from my M1 Mac running MacOS Ventura to my Macintosh Plus running MacOS 7.1. But when I try to open that application in the Macintosh I get the error message 'The document "Disk Copy 4.2.app" could not be opened because the program that created it could not be found. I get the same error message for 'Stuffit 3.5.1. hda'. Any idea what the problem is, since these files are themselves applications? My understanding is that it should work.
