I'd be interested in an answer as well. In my application I have multiple AVPlayers (some with video, some audio only) that are playing simultaneously. I would like to tap into the final mixed output that is going to speakers, so that I can send it to my streaming backend. For various technical reasons I to stay with the high-level AVPlayers. What is the recommended framework/technology for achieving this? AVAudioEngine look promising, but so far I have not found any way to attach a high-level AVPlayer to the lower-level AVAudioEngine. Are these two incompatible, or did I just miss something?

Same here on Monterey 12.2 - I had Safari running for a long time (with lots of open windows and tons of tabs). The UI for ASWebAuthenticationSession never showed up, even when trying multiple times. After quitting and relaunching Safari, all the queued requests for ASWebAuthenticationSession were handled in a serial fashion. This is clearly broken. Please fix in macOS 13.

I'm interested in using MPSImageGuidedFilter but haven't found any sample code on how to use it. It's API is quite different from all the other unary filters or binary filters in MPS. Any pointers?

Same problem with German keyboard. Hope that this will be fixed with 13.2.

I'm seeing similar behaviour whenever I procedurally modify the PKDrawing of a PKCanvasView. Specifially when doing: canvasView.drawing.strokes[i].mask = newMask canvasView.drawing.strokes[i] = newStroke canvasView.drawing.remove(at:i) canvasView.drawing.insert(stroke, at:i) the undoManager (or its stack of undo operations) gets messed up and stops working. I assume this is a bug in iOS 14 beta? Hopefully the PencilKit team will fix this before the release of iOS 14?
