I would like to know if macOS DEXT supports the following networking features: Tx/Rx Multiqueue, RSS, RSC, NS/ARP offload, PTP or packet timestamping and TSN. I couldn't find relevant documentation for these features in the Apple Developer Documentation. If they are supported, could you let me know which features are supported and how to find the corresponding official Apple documentation? Thanks

Hi, I’m developing my own Pcie Ethernet driverkit. My Pcie Ethernet card connect on Razor Core X and connect to MacBook via thunderbolt 3. The Problem: Click Driver application and send activate system extension request, then go to System setting -> Privacy & Security, in Extension section ->click “allow” , the peripherals malfunction immediately after "allow" clicked and type in the password.I can't control all peripherals devices like touchpad, keyboard and all of thunderbolt ports. However, it can regain functionality after plugging and unplugging the device. results I expected: User approve Driver Extensions enable and all peripherals work normally and Ethernet Card works. Has anyone encountered this problem? maybe something wrong in "OSSystemExtensionRequestDelegate" but I have no idea how to fix it Please Help. My Xcode version is Version 15.3 (15E204a). Thanks

My company has been developing a DriverKit Extension for our ThunderBolt attached devices. Our testing has gone well on Intel based machines but it seems to be able to cause kernel panics on my M1/M2 Mac when click "Allow" in Privacy & Security. It always crash immediately. Unfortunately it is " ApplePPMCPMS: Could not register client id 5. Error code 0xe00002bc " and I have no way to debug it. Has anyone deal with something like this? panic(cpu 5 caller 0xfffffe002fd92b7c): "ApplePPM: virtual IOReturn ApplePPMCPMS::callPlatformFunction(const OSSymbol *, bool, void *, void *, void *, void *):2003 " "ApplePPMCPMS: Could not register client id 5.

According to the WWDC202310224 "Simplify distribution in Xcode and Xcode Cloud" video, there are two questions about my development process. First, the developer must use "Development Profile" to config Signing &amp; Capability instead of "Developer ID Application profile" for building Applications? shown as the pictures below Second, after build application successfully with "Development Profile", process Product -&gt; archive will fail with "Command SetOwnerAndGroup failed with a nonzero exit code" error message, I have no idea how to solve this problem. Cloud you please tell me how to successfully archive the DriverKit application step by step and further directly distribute Application ? Thanks for your helpful support.

Xcode version : 14.0 Beta 3 macOS version : 13 Beta 3(22A5295i) Hi, I'm signing the DriverKit in Developer ID Application type profile with Developer ID Application (With Kext) type certificate on Xcode. But status shows error with"Xcode 14 and later requires a DriverKit development profile enabled for IOS and macOS.Visit the developer website to create or download a DriverKit profile" I have downloaded all profiles and Certificates to my Mac and installed all of them, then checked the website. I'm wondering what's different between "Development type" &amp; "Developer ID Application type" profile ? and the reason why "2022-07-22 14:41:54.162815+0800 0x22ee2    Error       0x0                  138    0    kernelmanagerd: Error occurred while handling request "DextLaunch(arguments: Optional(["Driver Extension Server Name": com.asix.dext.usbdevice, "Check In Token": 371, "Driver Extension Server Tag": 4294975444, "CFBundleIdentifier": com.asix.dext.usbdevice, "DriverKit Reslide Shared Cache": 0, "kOSBundleDextUniqueIdentifier": &lt;222f1e51 f5e890f7 b467c2a0 da761dbd 9b14dc5f 1bf56ff6 4eeab6b2 fed9683c&gt;]))": Error Domain=NSPOSIXErrorDomain Code=8 "Exec format error" error code show on when I starting the app. I'll appreciate that someone can give me some idea or suggestions.

Hi , I'm experiencing a weird crash on macOS 13 Beta3 when the app starts and I don't know what's causing it. I build this app in Xcode 14 Beta3 successfully and it can work normally in macOS &lt;= 12.5 The Translated Report said that "Exception Type: EXC_CRASH (SIGKILL (Code Signature Invalid)) " &amp; "Error Formulating Crash Report: dyld_process_snapshot_get_shared_cache failed" , I've tried so much to solve this problem but nothing worked. Is there anyone who can give me any suggestions or ideas to where I dig further? Thanks in advance for any suggestions. Attachments below are the log detail.
