Excuse me... but "drag and drop" was pioneered on the Apple Lisa (1982) and then on the Mac (1984).
Microsoft got "drag and drop" as a shareware application (Apporia) in Windows 2.0 (1988).

Sorry about that but I was never a fan of the Apple OS that I messed with as I was a Windows user for years and I forget the version Apple OS, but there wasn’t even a simple file management system equivalent to Windows Explorer, no built in disk defrag program (it used Norton’s Speed Disk which is notorious for frying HDD’s), other quirks that made me glad I never bought into the Apple hype. Whatever version of Apple OS I used, it seemed geared for the person that knew how to press the “on” button, and stuff like that.
