This is fantastic, thank you!! I just got a MacMini to try and figure this out again (still a beginner though). Is there a preferred iOS Device and iOS version of software that should be used? I have tried different versions going back to iOS 12.4, which is the oldest my M1 Mac Mini appears to support. Running gets the below error, and clicking "Cyanify!" button brings up the progress screen, but never finishes. I assume I am testing it wrong. 2021-12-22 18:52:16.689870-0800 AVReaderWriter[1873:38584] <CATransformLayer: 0x6000000f87a0> - changing property allowsGroupBlending in transform-only layer, will have no effect 2021-12-22 18:52:16.782267-0800 AVReaderWriter[1873:38750] [ddagg]    AggregateDevice.mm:878  couldn't get default input device, ID = 0, err = 0! thread_policy_set(1) returned 46
