My 2025 Hyundai Tucson SEL was doing fine with Apple CarPlay until last night's update, now it refuses to see/use CarPlay, both by bluetooth and by cable. Mind you, was working perfectly fine yesterday, it still sees my wife's phone via bluetooth and my son's phone via cable. The Tucson's last over-the-air update was 5/23/25, as in, nothing has changed with the Tucson, or my other family phones, which leaves only one variable that changed, my iPhone updating to the latest iOS developer beta.

Hello, I need to develop an application for a customer who is using an iPad. This application needs to read from and send data to a custom HID device connected via USB-C. Using USBDriverKit, the HID device can be detected when plugged into the iPad. However, when trying to open the device with the following code: ivars->interface = OSDynamicCast(IOUSBHostInterface, provider); ret = ivars->interface->Open(this, 0, NULL); It only returns e00002cd. I would like to ask if it is possible to access a custom HID device on iPadOS using USBDriverkit? Any help would be greatly appreciated!!

Hello. have zero by mar air, plan to learn xcode and swift, have to plaay on my local computer with Endpoint Security, is it really that i cannot do it without have dev id and pay 100$? thanks

Hi, In Linux we have this driver structure where the handlers are defined as below: static struct file_operations fops = { .owner = THIS_MODULE, .read = etx_read, .write = etx_write, .open = etx_open, .unlocked_ioctl = etx_ioctl, .release = etx_release, }; So when the user app calls open() with the appropriate file/device handle "etx_open" in the driver is acalled, etc. However, the Apple driver structure that is exposed to developers is different and it has changed drastically with the DriverKit architecture. I have some custom requests from the user app where I need to call this ioctl() type requests on my serial port "tty.myusbserial1234". My driver is derived from IOUserUSBSerial and is working fine for all other practical purposes except for such custom requirements. Has anyone encountered such a problem in MacOS DriverKit and what is the solution or an alternative? https://developer.apple.com/documentation/driverkit/communicating-between-a-driverkit-extension-and-a-client-app This gives a different approach, but the serial ports are accessed via open/read/write/close system calls and tcsetattr and other termios functions to set baud-rate and such. So, the above approcah is not suitable for my purpose. Any ideas/help is very much appreciated. Thanks.

My back camera freezes after first frame is displayed on the screen. Issue is present in all the apps that use the back camera. Same issue with front camera, however front camera works with Facetime and WhatsApp but not the native camera app.

I'm developing a CarPlay app and encountered an inconsistent behavior with template detection. When I present a CPActionSheetTemplate and then print the presentedTemplate property, it returns nil. However, when I present a CPAlertTemplate, the presentedTemplate property correctly returns the template object. This inconsistency is causing issues in my app where I need to check if there's already a presented template before showing another one to avoid conflicts. Why does CPActionSheetTemplate not get detected in presentedTemplate while CPAlertTemplate does? Is this intended behavior or a bug? Any guidance on how to properly detect if a CPActionSheetTemplate is currently presented would be greatly appreciated.

Starting with iOS 26, we've noticed that the accessoryImage in CPListItem is not working as expected in CarPlay. Previously, accessoryImage would appear in place of the accessoryType, but now it appears awkwardly next to the detailText, and the image itself is not rendering properly. We have submitted feedback to Apple multiple times, but the issue still persists in the latest beta releases. In general, there seem to be several CarPlay UI problems introduced in iOS 26. For example: In CPPointOfInterestTemplate, the pinImage is displayed at an excessively large size. Scroll positions in lists behave unexpectedly. CPInformationTemplate allows infinite scrolling, which seems unintended. Please take a look into these issues. Thank you.

Hello, dear Apple engineers. We have recently tried to pair our Android phones and iPhones via BLE SMP, but have encountered a very high probability of pairing failures. Through PacketLogger and Android phone HCI, we have determined that the issue is caused by the iOS side sending an SMP Pairing Failed message during the SMP process. Please help us analyze the reason for this.

We have developed the driver for the ProCapture video capture card based on PCIDriverKit. The App can communicate with the driver through the UserClient API. Currently, there is an issue where, when the App starts, there is a small probability that it causes a driver crash. However, the crash stack trace does not point to our code but appears to be within the PCIDriverKit framework. We have spent several weeks debugging but still cannot identify the root cause of the crash. Could you please review the crash log and suggest any methods to help pinpoint the issue? com.magewell.ProCaptureDriver-2025-09-15-153522.ips com.magewell.ProCaptureDriver-2025-09-15-082500.ips

Hello everyone, I'm developing a CarPlay app and am trying to test it with the dock on the right side of the screen, as is standard for right-hand drive vehicles like those in Japan. Currently, the CarPlay Simulator always displays the dock on the left, and I can't find an option to change its position. This is important for ensuring a proper user experience for my target market. Has anyone figured out how to configure the simulator for RHD layouts? Any guidance on how to move the dock to the right would be greatly appreciated. Thanks in advance for your help!

Hi, We were planning on using DriverKit to develop a USB Driver on IOS for iPhone. Within the DriverKit website, it say 'IOS16.0+' which lead us to believe it was compatible with iPhones running IOS16.0+. However, it appears DriverKit is only available for iPads running iPadOS, and computers running macOS. Are there any alternatives that would allow us to create a device specific USB driver for an iPhone running IOS?

Hi everyone, We are experiencing an issue with SMS messages sent from our banking app (iOS) to our customers. The SMS are being delivered by the carrier, but on iOS devices some of them appear to be filtered or blocked, and users don’t see them in the Messages app. This seems to be related to new SMS filtering rules on iOS (possibly affecting financial institutions and transactional SMS). • Has anyone faced a similar situation? • Are there specific Apple guidelines or best practices for SMS sender IDs / content to avoid being filtered? • Is there any official documentation from Apple regarding these new SMS filtering mechanisms? Any guidance or experiences would be greatly appreciated. Thanks in advance!

I have a USB-device with three interfaces: Vendor-Specific Bulk CDC Serial Control CDC Serial Data To configure the vendor specific bulk endpoints I need to send vendor specific control requests to endpoint 0. I'm using libusb for this task. As long as the interfaces for the CDC serial port are present I get an access error when trying to send vendor control requests. If I disable these CDC interfaces I can send vendor control request without any problems: Is this by design or ist there any possibility to send vendor control requests to the USB device while a CDC driver is active?

Hi, Is it possible for a macOS (or iOS/ipadOS) app to communicate with a CCID-compliant reader using the CCID interface (i.e., directly sending the PC_TO_RDR_* messages) instead of using the CryptoTokenKit API? Apple's CCID driver (/System/Library/CryptoTokenKit/usbsmartcardreaderd.slotd) seems to support all the PC_TO_RDR and RDR_TO_PC messages: https://blog.apdu.fr/posts/2023/11/apple-own-ccid-driver-in-sonoma/#enable-my-ccid-driver The background for this question is that we develop smartcard products and we'd like to use the finer grained settings provided by the CCID specification for testing/demo purposes. Thank you.

Hi, On macOS 11 and earlier versions, we provided users with the following script to uninstall our kext driver: sudo pkgutil --only-files --files com.magewell.ProCapture | tr '\n' '\0' | xargs -n 1 -0 sudo rm -vf sudo pkgutil --only-dirs --files com.magewell.ProCapture | grep ProCapture[^/]*$ | tr '\n' '\0' | xargs -n 1 -0 sudo rm -rvf sudo pkgutil --forget com.magewell.ProCapture sudo kextcache -system-caches However, this script no longer works on macOS 13 and returns the following error: It looks like you're trying to update the system caches. As of macOS 11, the personality cache is no longer in use for keeping kext matching information up-to-date. For more information, see `man kmutil`. This indicates we can no longer use kextcache -system-caches to clear our driver cache. This creates an issue where even after installing the new dext driver, the dext driver cannot run due to the presence of the old kext driver. We've tried various methods but haven't been able to completely uninstall the old kext driver - after every new system update, the old kext reappears. The specific process is as follows: This is the sequence I followed in my latest test - Device is running macOS 13 Ventura w/ 4247 Pro Capture kext driver installed kmutil inspect | grep -i magewell - this returns references to the kext files in /Library/Extensions, which is expected because I have not yet removed the 4247 kext driver - then I ran the following combination of your removal script and my removal steps: cd / sudo rm -r /Library/Extensions/ProCaptureDriver.kext sudo rm -r /Library/Extensions/ProCaptureEvent.kext sudo rm /System/Volumes/Preboot/*/boot/*/System/Library/Caches/com.apple.kernelcaches/kernelcache.auxkc* sudo pkgutil --only-files --files com.magewell.ProCapture | tr '\n' '\0' | xargs -n 1 -0 sudo rm -vf sudo pkgutil --only-dirs --files com.magewell.ProCapture | grep ProCapture[^/]*$ | tr '\n' '\0' | xargs -n 1 -0 sudo rm -rvf sudo pkgutil --forget com.magewell.ProCapture sudo kextcache --clear-staging sudo kcditto sudo kmutil install --update-preboot sudo shutdown -r now - After this I ran 'kmutil inspect | grep -i magewell' and got no results, which seems good but... - then I ran the upgrade to macOS 15.7 Sequoia - Afterwards I ran 'kmutil inspect | grep -i magewell' and it returned references to the old /Library/Extensions kexts again, although the files no longer exist in /Library/Extensions - I then ran my cleanup process again (slightly different for Sequoia-available commands): sudo rm /System/Volumes/Preboot/*/boot/*/System/Library/Caches/com.apple.kernelcaches/kernelcache.auxkc* sudo kextcache --clear-staging sudo kmutil rebuild sudo kcditto sudo kmutil install --update-preboot sudo shutdown -r now - Then I ran 'kmutil inspect | grep -i magewell' and got no results again - As a next test I ran a minor update to macOS 15.7.1, then ran 'kmutil inspect | grep -i magewell' and the references to the old kexts came back again We have indeed identified a solution to address this issue: kmutil trigger-panic-medic --volume-root /Volumes/<YourVolumeName> However, this method requires booting into Recovery Mode, which is unacceptable for many of our customers. Especially for those who need bulk remote management, having personnel physically operate each machine one by one is simply not feasible. Therefore, is there a method to completely uninstall the kext driver while in normal mode? Thank you!

I want to turn off this effect and maintain the style before iOS18. Do I need to add content about iOS26 to the info.plist? Specifically, which content is it? I want to turn off the glass effect on the button

Hi everyone, We are in the process of migrating a legacy KEXT for our external multi-disk RAID enclosure to the modern DriverKit framework. During the performance validation of our KEXT, we observed a large and consistent maximum throughput difference between Intel-based Macs and Apple Silicon-based Macs. We would like to share our findings and hope to discuss with others in the community to see if you have had similar experiences that could confirm or correct our understanding. The Observation: A Consistent Performance Gap When using the exact same external RAID hardware (an 8-HDD RAID 5 array), driven by our mature KEXT, we see the following results in high-throughput benchmarks (AJA System Test, large sequential writes): On a 2020 Intel-based Mac: We consistently achieve a throughput of ~2500 MB/s. On modern M-series Macs (from M1 to M4): The throughput is consistently capped at ~1500 MB/s. This performance difference of nearly 40% is significant and is present across the entire Apple Silicon product line. Our Hypothesis: A Shift in Architectural Design Philosophy Since the KEXT and external hardware are identical in both tests, we believe this performance difference is not a bug but a fundamental platform architecture distinction. Our hypothesis is as follows: 1. The Intel Mac Era ("Dedicated Throughput") The Intel-based Macs we tested use a dedicated, discrete Intel Thunderbolt controller chip. This chip has its own dedicated PCIe lanes and resources, and its design appears to be singularly focused on maximizing raw, sustained data throughput for external peripherals. 2. The Apple Silicon Era ("Integrated Efficiency") In contrast, M-series Macs use a deeply integrated I/O controller inside the SoC. This controller must share resources, such as the total unified memory bandwidth and the chip's overall power budget, with all other functional units (CPU, GPU, etc.). We speculate that the design priority for this integrated I/O controller has shifted from "maximizing single-task raw throughput" to "maximizing overall system efficiency, multi-task responsiveness, and low latency." As a result, in a pure, single-task storage benchmark, its performance ceiling may be lower than that of the older, dedicated-chip architecture. Our Question to the Community: Is our understanding correct? Have other developers of high-performance storage drivers or peripherals also observed a similar performance ceiling for external storage on Apple Silicon Macs, when compared to high-end Intel Macs? We believe that understanding this as a deliberate architectural trade-off is crucial for setting realistic performance targets for our DEXT. Our current goal has been adjusted to have our DEXT match the KEXT's ~1500 MB/s on the M-series platform. Any insights, confirmations, or corrections from the community or Apple engineers would be greatly appreciated. Thank you very much! Charles

Hello, I'm trying to make a DEXT for a thunderbolt device. I started from the DriverKit template that does a very simple Hello World.

Hello everyone, We are migrating a KEXT storage driver to DriverKit. In our KEXT, we use a "one LUN = one Target" model and successfully create multiple targets in a loop during initialization. We are now trying to replicate this architecture in our DEXT. The issue is that only Target 0 is fully probed and mounted. For Target 1, the lifecycle silently stops after the first TEST UNIT READY command is successfully acknowledged. The macOS SCSI layer never sends any subsequent probe commands (like INQUIRY) to this target. The failure sequence for Target 1, observed from our logs (regardless of whether Target 0 is created), is as follows: AsyncCreateTargetForID(1) -> UserInitializeTargetForID(1) (Succeeds) UserProcessParallelTask(Target: 1, Opcode: TUR) (Succeeds) The DEXT correctly acknowledges the TUR command for Target 1 by returning kSCSITaskStatus_CHECK_CONDITION with UNIT ATTENTION in the Sense Data (Succeeds) <-- Breakpoint --> UserProcessParallelTask(Target: 1, Opcode: INQUIRY) (Never happens) Through log comparison, we have confirmed that the DEXT's response to the TUR command for Target 1 is identical to the successful KEXT's response. We have tried creating only Target 1 (skipping Target 0 entirely), but the behavior is exactly the same -> the probe still stalls after the TUR. We initially suspected a race condition caused by consecutive calls to AsyncCreateTargetForID(). We attempted several methods to ensure that targets are created sequentially, such as trying to build a "creation chain" using OSAction completion handlers. However, these attempts were unsuccessful due to various compilation errors and API misunderstandings. In any case, this "race condition" theory was ultimately disproven by our experiment where creating only Target 1 still resulted in failure. We would like to ask two questions: Is our inability to have a Target ID greater than 0 fully probed by macOS a bug in our own code, or could there be another reason we are unaware of? If we do indeed need a "one-after-another" creation mechanism for AsyncCreateTargetForID, what is the correct way to implement a "chained creation" using OSAction completion handlers in DriverKit? Thank you for any help or guidance. Best Regards, Charles
