I've been doing a lot of Mac development recently. This means I often need to screen share to my headless OS X Mountain Lion system for testing. This morning, I was updating my folderol app to add features for folder tagging. I had to make sure that those Mavericks-only features wouldn't show up when the app was run on 10.8.
Normally, I mount the headless system as a foreign disk drive and then copy/drag to the drive using finder. But for whatever reason today, I thoughtlessly dragged the app directly to the shared desktop. And I'll be gobsmacked, but it worked. The file just transferred, and a new File Transfer window opened to show me that the process was successful:
I honestly have no idea how long this feature has been around. For all I know it goes back to the OS X stone ages. [It does go back quite a ways... drag and drop file transfers using Apple Remote Desktop were introduced in v3 back in late 2006. –Ed.] But I also know that if it was a pleasant surprise to me, some of you out there will appreciate knowing about it too.
