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

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?
