Instead, [NSPasteboard](https://developer.apple.com/documentation/appkit/nspasteboardtype?language=objc) is used. There is a set of [globally known types](https://developer.apple.com/documentation/appkit/nspasteboardtype?language=objc) but your program can also register a [new UTI](https://developer.apple.com/library/archive/documentation/FileManagement/Conceptual/understanding_utis/understand_utis_declare/understand_utis_declare.html#//apple_ref/doc/uid/TP40001319-CH204-SW4) and use that instead. Again, MIME type doesn't come into play.

I apologize again for asking in the wrong place. But it seems I stumbled into the right guy to ask:) There are many new terms for me. It sounds like although Qt takes arguments in the MIME type, but behind the scenes it converts to whatever the system understands. It just so happens that apple os (or NSPasteboard) don't have a standard type for svg, as I can't find it in the [list](https://developer.apple.com/documentation/appkit/nspasteboardtype?language=objc) you mentioned. But windows clipboard does use MIME so there's no problem?
