excuse me, how did you got "descriptors.mtlp-json", I have tried below scenarios but all I got is just ***.metallib xcrun metal-source -flatbuffers=json binaryArchive_1007_iOS16_.metallib -o ./descriptors3.mtlp-json or xcrun air-lipo binaryArchive_1007_iOS16_.metallib -thin applegpu_g13p -output applegpu_g13p.metallib xcrun metal-source -flatbuffers=json applegpu_g13p.metallib -o ./descriptors3.mtlp-json

Got it ~~ Thank you ~~

Thank you for the response, how about patch? Does binary archives compatible between different patch, for example iOS14.4.1 and iOS14.4.2~ Thank you~

Great, thank you for the guide, I will try it now~

Hi, Thank you for the quick response. I just double checked it, and some interesting things happened, below are the scenarios: 1.install the app, reboot, start the app with instrument immediately, and some strange part “Create MTLibrary(mediaserverd)” with grey color occured. 2.install the app, reboot, start some other apps, play some minutes, and then start the app with instrument, anything goes fine, without the strange part “Create MTLibrary(mediaserverd)” with grey color, and also nearly without the part "Create MTLibrary(TestProj)" with purple color, as we expect 3.install the app, reboot, wait for some minutes, and then start the app with instrument, only a few strange part “Create MTLibrary(mediaserverd)” with grey color left, and also nearly without the part "Create MTLibrary(TestProj)" with purple color. The picture of instrument as below:[linkText](https://developer.apple.com/forums/content/attachment/7f9a1447-2974-465c-9396-ffaf8117fbb8)
