Hello everybody,
Since macOS 15, the systemextension allow in changed as switch style and put in the "Login items & Extensions". I know the URL navigating to here, which is:
x-apple.systempreferences:com.apple.LoginItems-Settings.extension
But the extension options we need to scroll deep down and we need to click the "!" to open it.
I want to open the finally window for user can easily see it and enable it. Please tell me how. Appreciate!!

Is there an option to create a macOS filter driver for the IONVMeFamily Driver that would enable sending NVMe Admin commands( likes security send , security receive, Firmware download)? This approach would allow us to reuse the IO path provided by the family driver.
Hello,
I'm developing a custom AU plugin that needs to connect to a DriverKit driver. Using the DriverKit sample (https://github.com/DanBurkhardt/DriverKitUserClientSample.git), I was able to get a standalone app to connect to the driver successfully. However, the AU plugin, running in a sandboxed host, isn't establishing the connection. I’ve already added the app sandbox entitlement, but it hasn’t helped. Any advice on what might be missing?
TIA!
My APP is not a game APP but I entered game mode when opening the APP on IOS 18. Setting GCSupportsGameMode = false is also invalid
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
Hello.
In the case of certain apps, I confirmed that when I connected the Bluetooth of the vehicle, local notification is activated in the app and the app processor automatically runs when Bluetooth is connected. How can I do that?
Thank you
In iPadOS 17.7 my driver shows up in settings just fine. After recompiling with Xcode 16 and installing my app (containing my driver) on iPadOS 18, the app shows up in settings but the driver-enable button is missing from Settings. When I plug-in my custom USB device, the app cannot detect it and I am left with no way to manually enable the driver, as I did in the previous version of iPadOS.
I'm working on a DriverKit driver. I have it running on macOS, including a very simple client app written in SwiftUI. Everything is working fine there. I've added iPadOS as a destination for the app as demonstrated in the WWDC video on DriverKit for iPadOS. The app builds and runs on my iPad, as expected (after a little work to conditionalize out my use of SystemExtensions.framework for installation on macOS). However, after installing and running the app on an iPad, the driver does not show up in Settings->General, nor in the app-specific settings pane triggered by the inclusion of a settings bundle in the app.
I've confirmed that the dext is indeed being included in the app bundle when built for iPadOS (in MyApp.app/SystemExtensions/com.me.MyApp.MyDriver.dext). I also can see in the build log that there's a validation step for the dext, and that seems to be succeeding.
I don't know why the app isn't being discovered -- or in any case surfaced to the user -- when the app is installed on the iPad. Has anyone faced this problem and solved it? Are there ways to troubleshoot installation/discovery of an embedded DriverKit extensions on iOS? Unlike on macOS, I don't really see any relevant console messages.
Upgraded my 2 machines to Sequoia 15 and consequently I am unable to print or scan with both machines.
A 3rd machine which is not upgraded as yet is unaffected. AirPrint from iPhones is not affected.
The printing process executes without error. The printer receives the job but does not actually execute the print. The machine behaves like the job in the queue is completed normally. No error message. Just no physical printout.
Happens with all applications.
When Scanning - fails to connect to device to enable scanning. error message after some time is attached
Hello, as the title says, I am trying to access Bluetooth in a system daemon. I am running on MacOS Sonoma 14.5.
When initializing Bluetooth, my daemon received Unauthorized state.
I have tried to add my daemon in the system settings (System Preferences > Security & Privacy > Privacy > Bluetooth) "Allow applications to access Bluetooth" by adding the program executable path defined by the entry Program of my system daemon as suggested here: https://developer.apple.com/forums/thread/662459.
But I am still having the issue.
Writing a system daemon with Bluetooth is not my final goal. The bigger picture is the smartcard reader driver with Bluetooth access which as the same issue and the solution is probably related.
I do not remember how but my smartcard reader driver use to work with Bluetooth but it does now with the same Unauthorized error.
As far as I can see daemon and smartcard drivers does not have support for entitlement.
Here are the logs for my sample system daemon:

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

The following exceptions occur when I try to archive a version of this app. It runs fine in DEBUG - ive bashed my head through all github forums and stack overflow posts trying all fixes:
deleting the duplicate pods in xcode - cause a hermes error which then fails ALL builds
the following all show the same symptoms (same error ONLY in an archive build)
adjusting pod file to eliminate duplicates
inserting a script in build phases
have checked info.plist, project.pbxproj and other key files

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!
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.

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;
}
I struggle to add custom properties to my streams as described in the WWDC22 video https://developer.apple.com/videos/play/wwdc2022/10022/
minute 28:17
The speaker describes using this technique in his CIFilterCam demo (would the source code be available please?) to let the app control which filter the extension should apply.
Presumably, there's thus a way to:
1 - define a custom property in the camera extension's stream/device/provider?
2 - be able to use CoreMediaIO (from Swift?) in the app in order to set values of that custom property.
This is not documented anywhere I could find.
Help and sample code would be greatly appreciated.
Thank you.
