Shell extensions are the single most common cause of Explorer crashes according to Raymond Chen.

When you realized that Mac OS X didn’t have an equivalent API, did you perhaps consider that it was for a good reason and that you should redesign your application to fit the conventions of the system? How did you conclude that your UI was oh so special that it deserved horking up the Finder experience for your users?

I don’t understand. Any MacOS Finder that had an open file handle into an application bundle runs on the Unix version of MacOS, and that allows deletion of open files (the inode stays around until the process exits), doesn’t it?

Or did/does the Finder check whether to-be-deleted files are open? Or did I forget how older Mac file systems behaved?

You can't really blame macOS for this one. Interesting to hear this isn't just a Windows thing though.

You seem to be blaming the OS for how you broke it?

As a mac user for 10+ years that cycled about 7 macs for personal and professional use, I've used Finder about biweekly to click on the airdrop button..
