It’s very hard for a sandboxed app to get access to the internals of Photos without using MLMediaLibrary, though not too difficult for non-sandboxed. MLMediaLibrary was added because of this need. There is a standard component - NSMediaLibraryBrowserController (https://developer.apple.com/reference/appkit/nsmedialibrarybrowsercontroller?language=objc) that gives you a standardised panel for browsing. Unfortunately it’s a standalone panel rather than a view that you can embed within a larger UI, but it’s sufficient for many needs, and is easy to use. You could look at that and see if its behaviour is more reliable than your own code. I have tried it and it isn’t for me - I get the same problems with it that I see in NSOpenPanel, or when using KVO on MLMediaLibrary elements, which is why the problem seems to be in the lower-level layers of MLMediaLibrary. —Graham _______________________________________________ Cocoa-dev mailing list (Cocoa-dev@lists.apple.com) Please do not post admin requests or moderator comments to the list.
