Thanks @DTS Engineer . Waiting for news

@DTS Engineer , I've also successfully uploaded sysdiagnose and attach video links into the ticket by Feedback Assistance. The issue with Feedback Assistance is...they just do NOT respond. I've created it initially 18 Sep 2024 and no response there... So here I hope to find help and also ask you for it too!

@DTS Engineer I have created fresh virtual machine with latest macOS, installed latest Xcode there and check. Behavior is still broken (check video below). https://drive.google.com/file/d/1THJ-o_4htaP2FvH8w4nt8IsbIsNefgZk/view?usp=sharing As you requested, I've also collected sysdiagnose: https://drive.google.com/file/d/1xv11WVYlVjCEVmggr37cETbqd-5w8Yyd/view?usp=sharing

@DTS Engineer , have you checked the videos I've attached? They clearly shows what is wrong Bug report number is FB15166590

Same bug for me. Developer ID Application cert is expiring soon and I dont even see this option while creating new certificate

@dazy_naoki , adding "import os" resolves issue for me

@Drewbadour , followed your advice. Created for test purposes DEXT with 2 IOServices of IOUserResources kind. Now facing two problems: Somewhy they are launched in separate processes. I.e. after DEXT is loaded, there are two instances of DEXT process, one per IOService. Doy you know what IOPersonalities keys should match to force DEXTs to be loaded as single process? ServiceNotificationReady callback is not called. Example above is replicated accurately. Can you suggest any ideas why?

I'm working of functional like USB device filtering. So it adds some restrictions I have to make a decision about plugged device before Start succeeds or fails IOUserClient, as I understood, used for App<->DEXT communication, but not DEXT<->DEXT. Am I right? Conceptually, I need some way to prepare IOService kind of IOResources that starts on DEXT bootstrap and can be reached within the App each time USB device is connected, I need to obtain set of rules to filter particular USB device/interface. This can be achieved by communicating inside DEXT if I could have such mechanism
