Here is project I am researching: https://developer.apple.com/documentation/hiddriverkit/handling_stylus_input_from_a_human_interface_device I have a Touch screen and I want: can control this screen, I can enable extension and control Touch screen successfully. can pen on this screen. To do this, I need to send X,Y to StylusApp(AppKit) But I Can not send X, Y to Swift StylusApp Eventhough I can log X,Y it by default code: But I don't know how to send it to AppKit to Pen. I have research about communicate Driver and Client: https://developer.apple.com/documentation/driverkit/communicating_between_a_driverkit_extension_and_a_client_app#4324306 but seem HID driver don't support inheritance from IOUserClient:

how can i upgrade my mac 10.13 if it does let me go to [https://beta.apple.com/sp/betaprogram/apfsfusion]. page

I'm try to use CoreHID to communicate with a usb hid device that sends custom reports. I have been able to create a client, but when I try to access the elements I get this: IOServiceOpen failed: 0xe00002e2 also in: client.monitorNotifications(reportIDsToMonitor: [HIDReportID.allReports], elementsToMonitor: []) {... What do I put into "elementsToMonitor: []" array?

Hi guys, I am developing an iOS application that turns iPhone into a HID peripheral. I have successfully added services and characteristics, and it can be paired with a Windows PC and works as expected. However, after the app relaunch and services re-added, PC not able to re-connect to it automatically. It still shows "Paired" on the PC rather than "Connnected" and no subscribe event received from CB. The user has to remove the device and do the pair again. I think the reason is that a new peripheral manager created after re-launch, it doesn't have previous connections' information (uuid or secure key). Hence, PC not able to talk to it anymore. My questions are: Is it the real reason for this? Any chance app can store the peripheral manager or the connection information? So that can pick it up next run. Any chance can setup to "Just works" mode? Maybe can make the reconnection working? I have read thru the CB documents, and didn't find answer there. Just trying with the forum if any luck...

since I downloaded the iOS 18.1 beta, my twint apps aren‘t working anymore They crash as soon as i select the app icon

Hello, I am trying to get value of InterfaceClass for particular USB Device. I modified matching dictionary and added the property locationID property. CFMutableDictionaryRef matchingDictionary = IOServiceMatching(kIOUSBInterfaceClassName); if (!matchingDictionary) { return -1; } int32_t locationID = 0xffff; CFNumberRef cfLocationID = CFNumberCreate(kCFAllocatorDefault, kCFNumberSInt32Type, &locationID); CFDictionaryAddValue(matchingDictionary, CFSTR(kUSBHostPropertyLocationID), cfLocationID); CFRelease(cfLocationID); io_service_t ioService = IOServiceGetMatchingService(kIOMasterPortDefault, matchingDictionary); if (!ioService) { return -1; } CFNumberRef cfInterfaceClass = (CFNumberRef)IORegistryEntrySearchCFProperty(ioService, kIOServicePlane, CFSTR(kUSBHostMatchingPropertyInterfaceClass), kCFAllocatorDefault, kNilOptions); ... Unfortunately nothing is found and ioService is NULL. What can be wrong here? Thank you in advance!

I am on a 2021 24" M-1 iMac running Sonoma 14.5. I've recently acquired Universal Audio's Apollo Twin X DAW. I'm recording with Logic Pro X software. I've already gone through the Mac security instructions to get the Apollo Twin X installed, but I am getting little onscreen warnings from Apple saying that my set up may not be compatible with upcoming iOS updates. UA is pointing the finger at Apple. So, what gives? Will Apple updates welcoming Universal Audio Apollo Twin X into its world seamlessly? I am avoiding updating my iOS because of this issue.

since the installation of iOS 18 beta 7 can no longer see my music in messenger note. Was there in beta 6. need help to fix the bug. Thanks

I created a camera extension project that required interaction via custom properties. I originally coded it on macOS 14.x. In the camera extension code, receiving and returning NSNumber values as shown in the code at the bottom. The app was working perfectly until I went to test on mac 12.7.6. Under that version of macOS, the custom properties weren't working at all. I also saw lines in the logs like this: CMIO_DAL_CMIOExtension_Stream.mm:1165:GetPropertyData 50 wrong 4cc format for key 4cc_back_glob_0000 which was totally perplexiing, because it was clear that the 4cc codes were fine under 13.x, especially given that the documentation for CMIOExtensionPropertyState clearly says that NSNumbers should be OK. On a hunch, I changed the code to use NSString instead of NSNumber, and it started working again under 12.7.6. So, my experience is that macOS 12.x doesn't allow you to use NSNumbers, but it happy with NSStrings. Hope that saves someone else some time. And here is is the code that worked on 14.x, but not on 12.x. // 4cc constant const CMIOExtensionProperty CMIOExtensionPropertyCustomPropertyData_BackgroundOption = @"4cc_back_glob_0000"; - (nullable CMIOExtensionDeviceProperties *)devicePropertiesForProperties:(NSSet<CMIOExtensionProperty> *)properties error:(NSError * _Nullable *)outError { // doesn't work on macOS 12.x, works on 14.x CMIOExtensionDeviceProperties *deviceProperties = [CMIOExtensionDeviceProperties devicePropertiesWithDictionary:@{}]; if ([properties containsObject:CMIOExtensionPropertyCustomPropertyData_BackgroundOption]) { NSNumber* nsBackgroundOption = [NSNumber numberWithUnsignedInt:(unsigned int)_backgroundOption]; CMIOExtensionPropertyState* state = [CMIOExtensionPropertyState propertyStateWithValue:nsBackgroundOption]; [deviceProperties setPropertyState:state forProperty:CMIOExtensionPropertyCustomPropertyData_BackgroundOption]; } return deviceProperties; } - (BOOL)setDeviceProperties:(CMIOExtensionDeviceProperties *)deviceProperties error:(NSError * _Nullable *)outError { // doesn't work on macOS 12.x, works on 14.x NSDictionary* devicePropertiesDict = [deviceProperties propertiesDictionary]; CMIOExtensionPropertyState* propState = nil; propState = [devicePropertiesDict objectForKey:CMIOExtensionPropertyCustomPropertyData_BackgroundOption]; if (propState != NULL) { NSNumber* nsBackgroundOption = [propState value]; if (nsBackgroundOption != NULL) { uint32_t newBackgroundOption = [nsBackgroundOption unsignedIntValue]; if (newBackgroundOption != _backgroundOption) { log_info(@"##### Set Background Option to %d", (int) newBackgroundOption); } _backgroundOption = newBackgroundOption; } } return YES; }

Investigating a kernel panic, I discovered that Apple Silicon Panic traces are not working with how I know to symbolicate the panic information. I have not found proper documentation that corrects this situation. Attached file is an indentity-removed panic, received from causing an intentional panic (dereferencing nullptr), so that I know what functions to expect in the call stack. This is cut-and-pasted from the "Report To Apple" dialog that appears after the reboot: panic_1_4_21_b.txt To start, I download and install the matching KDK (in this case KDK_14.6.1_23G93.kdk), identified from this line: OS version: 23G93 Kernel version: Darwin Kernel Version 23.6.0: Mon Jul 29 21:14:04 PDT 2024; root:xnu-10063.141.2~1/RELEASE_ARM64_T8122 Then start lldb from Terminal, using this command: bash_prompt % lldb -arch arm64e /Library/Developer/KDKs/KDK_14.6.1_23G93.kdk/System/Library/Kernels/kernel.release.t8122 Next I load the remaining scripts per the instructions from lldb: (lldb) settings set target.load-script-from-symbol-file true I need to know what address to load my kext symbols to, which I read from this line of the panic log, after the @ symbol: com.company.product(1.4.21d119)[92BABD94-80A4-3F6D-857A-3240E4DA8009]@0xfffffe001203bfd0->0xfffffe00120533ab I am using a debug build of my kext, so the DWARF symbols are part of the binary. I use this line to load the symbols into the lldb session: (lldb) addkext -F /Library/Extensions/KextName.kext/Contents/MacOS/KextName 0xfffffe001203bfd0 And now I should be able to use lldb image lookup to identify pointers on the stack that land within my kext. For example, the current PC at the moment of the crash lands within the kext (expected, because it was intentional): (lldb) image lookup -a 0xfffffe001203fe10 Which gives the following incorrect result: Address: KextName[0x0000000000003e40] (KextName.__TEXT.__cstring + 14456) Summary: "ffer has %d retains\n" That's not even a program instruction - that's within a cstring. No, that cstring isn't involved in anything pertaining to the intentional panic I am expecting to see. Can someone please explain what I'm doing wrong and provide instructions that will give symbol information from a panic trace on an Apple Silicon Mac? Disclaimers: Yes I know IOPCIFamily is deprecated, I am in process of transitioning to DriverKit Dext from IOKit kext. Until then I must maintain the kext. Terminal command "atos" provides similar incorrect results, and seems to not work with debug-built-binaries (only dSYM files) Yes this is an intentional panic so that I can verify the symbolicate process before I move on to investigating an unexpected panic I have set nvram boot-args to include keepsyms=1 I have tried (lldb) command script import lldb.macosx but get a result of error: no images in crash log (after the nvram settings)

I am facing a problem as per the title. I tried possible options as per the guidance in other forums here but still facing the same problem. Even I can't connect my AirPods. Is there any help?

Is there a way to detect at run-time whether the device supports USBDriverKit?

I'm using the following code to find the dext service. The driver is enabled in iOS settings prior to launching the app. io_service_t mService = IO_OBJECT_NULL; kern_return_t ret = kIOReturnSuccess; io_iterator_t iterator = IO_OBJECT_NULL; if (__builtin_available(iOS 15.0, *)) { ret = IOServiceGetMatchingServices(kIOMainPortDefault, IOServiceNameMatching("MyDriver"), &iterator); } else { // Fallback on earlier versions } if (ret != kIOReturnSuccess) { printf("Unable to find service"); } while ((mService = IOIteratorNext(iterator)) != IO_OBJECT_NULL) { //Only able to find service if launching the app first and then connecting the device .......... } I noticed the call IOServiceNameMatching doesn't return the same result for the following workflows: Launch the app first and then connect the device, IOServiceGetMatchingServices can find the service. Connect the device to USB-C port first, then launch the app, the same call can't find a matching service (iterator is null). I would need to disconnect and reconnect the device while the app is running in order to find the matching dext. Any suggestion on how to find the matching dext service for workflow #2? Thanks

I explored Apple's Filtering Network Traffic sample. I noticed for me, FilterDataProvider's startFilter method is called only when I make filterManager.grade = .inspector before calling filterManager.saveToPreferences. Could someone help why the startFilter is not called when I leave the filterManager's grade property with it's default value. i.e NEFilterManagerGradeFirewall? https://developer.apple.com/documentation/networkextension/filtering_network_traffic

Hello team, I am using USBDriverKit and Driverkit framework in my application for communication of USB device. After updating my iPad OS to 18 public beta, I am unable to get option to enable drivers in my setting page of my application. However, I am able to see that options in developer beta version of iPad OS 18. Can anyone guide me, how should I proceed further as I am unable to use my USB devices.

Can anyone definitively say if USBDriverKit is supported on the new OS and 3.2 USB iPhone device? This would be a fantastic way to work with novel devices such as custom cameras. Thanks.
