How to programmatically open a file of any type on OS X?

Question

I've tried this:

var openedSuccessfully = AppKit.NSWorkspace.SharedWorkspace.OpenFile(filePath);

It seems to work, except for those file types which have no default app associated with them. When I try to open such a file from Finder, I get this dialog:

Is there a way to programatically open this (or similar) app chooser window?

Answer 1

Try the openFile:withApplication method, setting the application to Finder. That should open the app chooser window, or the default app, as appropriate.

// Opens app chooser
AppKit.NSWorkspace.sharedWorkspace().openFile(unknownFile, withApplication: "Finder") 
// Opens default application
AppKit.NSWorkspace.sharedWorkspace().openFile(knownFile, withApplication: "Finder")

Xamarin.Mac Format:

NSWorkspace.SharedWorkspace.OpenFile(knownFile, "Finder");

Answer 2

Swift 5

NSWorkspace.shared.openFile(YOUR_PATH)
