Hello Everyone, I am trying to develop a DriverKit for RAID system, using PCIDriverKit & SCSIControllerDriverKit framework. The driver can detect the Vendor ID and Device ID. But before communicating to the RAID system, I would like to simulate a virtual Volume using a memory block to talk with macOS. In the UserInitializeController(), I allocated a 512K memory for a IOBufferMemoryDescriptor* volumeBuffer, but fail to use Map() to map memory for volumeBuffer. result = ivars->volumeBuffer->Map( 0, // Options: Use default 0, // Offset: Start of the buffer ivars->volumeSize, // Length: Must not exceed buffer size 0, // Flags: Use default nullptr, // Address space: Default address space &mappedAddress // Output parameter ); Log("Memory mapped completed at address: 0x%llx", mappedAddress); // this line never run The Log for Map completed never run, just restart to run the Start() and makes this Driver re-run again and again, in the end, the driver eat out macOS's memory and system halt. Are the parameters for Map() error? or I should not put this code in UserInitializeController()? Any help is appreciated! Thanks in advance. Charles

Hi, our CoreAudio server plugin supports different clock sources. A switch might result in a change of the selectable sample rates (and other settings). On a clock source switch the plugin reconfigures the set of available kAudioStreamPropertyAvailablePhysicalFormats and announces the change via AudioServerPlugInHostInterface::PropertiesChanged(). However at least the Audio MIDI Setup seems to ignore to update it's UI. The changes are first reflected after selecting another device and re-selecting the device of interest. (Latest macOS, M4 macMini) Is this a bug? Or is our CoreAudio server plugin required to indicate the change in the list of available audio formats differently? 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.

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!

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?

I'm trying to implement a virtual serial port driver for my ham radio projects which require emulating some serial port devices and I need to have a "backend" to translate the commands received by the virtual serial port into some network-based communications. I think the best way to do that is to subclass IOUserSerial? Based on the available docs on this class (https://developer.apple.com/documentation/serialdriverkit/iouserserial), I've done the basic implementation below. When the driver gets loaded, I can see sth like tty.serial-1000008DD in /dev and I can use picocom to do I/O on the virtual serial port. And I see TxDataAvailable() gets called every time I type a character in picocom. The problems are however, firstly, when TxDataAvailable() is called, the TX buffer is all-zero so although the driver knows there is some incoming data received from picocom, it cannot actually see the data in neither Tx/Rx buffers. Secondly, I couldn't figure out how to notify the system that there are data available for sending back to picocom. I call RxDataAvailable(), but nothing appears on picocom, and RxFreeSpaceAvailable() never gets called back. So I think I must be doing something wrong somewhere. Really appreciate it if anyone could point out how should I fix it, many thanks!

I would like to write a driver that supports our custom USB-C connected device, which provides a serial port interface. USBSerialDriverKit looks like the solution I need. Unfortunately, without a decent sample, I'm not sure how to accomplish this. The DriverKit documentation does a good job of telling me what APIs exist but it is very light on semantic information and details about how to use all of these API elements. A function call with five unexplained parameters just is that useful to me. Does anyone have or know of a resource that can help me figure out how to get started?

I am trying to open the CommunicationControl class IOUSBHostInterface in my USB driver, but it only seems to open on iPad Airs and not iPad Pros. I'm calling ivars->interruptInterface->Open(this, 0, NULL); After retrieving the interruptInterface from the device's InterfaceIterator. I try and open this, but on iPad Pros it returns kIOReturnNotOpen. I've tried closing and reopening the IOUSBHostDevice, closing and reopening the Interface, AbortDeviceRequests before opening, etc. but it just seems to work on iPad Air and not iPad Pro. I've tried on both iPadOS 17.6.1 and 18.2 Has anyone else seen this?

Hey, I'currently working on a Driver (and its App) for iPadOS (USB Device). I think have the right entitlements, as my driver gets installed with the app properly (after accepting it in the settings). It also gets loaded once the device is plugged in and so on. However the Kernel is not using the updated Version after I install a new Version of App and Driver to the iPad (at least most of the times). I'm verifying this by reading out the Logs via Console and the Driver prints its Build number on Start(). Sometimes it works like it should but I found no pattern. As far as I understand the iPad should automatically install the new Version of the Driver with the new App if its Build is different from the current one. I'm incrementing the Build of App and Driver automatically post-build so each build the iPad gets has its own Build number (This also works). Steps to reproduce: Cleaning Xcode Build Folder Unplugging the USB Device from the iPad. Building and Installing a new Version of the Driver and the App via Xcode (making sure the build number has changed) Plugging the USB back into the iPad Reading Console output of the iPad However it works (each time if I: Uninstall the app from the iPad manually or via Devices in Xcode Build and install the App via Xcode Open the Settings App and activate the Driver But uninstalling the App each time is taking a lot of time and manual Steps so I would like to fix this issue. Do you have any Ideas? Thanks, Bjarne

Is anyone having any luck getting there phone fixed? I have recently done the iOS 18.1 update and then my phone camera has stopped working. i don’t appear to be on my own either but burnt seeing any positive posts about apple cooperating? not sure how it can be my fault if their software has caused it? I am out of warranty too

i tried opening iMovie for the first time on my 2017 Macbook Air but i get an error saying that iMovie is too new to my mac but i was trying to run the built in one it says i need to downgrade it on the appstore but there is no option to downgrade

I am getting an unexpected crash from IOService::Create() when attempting to create a new user-client. The crash is a nullptr exception in OSCopyInObjects(). The last call from my code was IOService::Create(). As far as I can tell, all the input parameters to Create() are correct, and the Info.plist is has the correct key and class information - indeed, if I corrupt these I get an error status return rather than a crash. Any suggestions as to what could be causing this? I suspect that the problem may be related from a change in the underlying application that is creating the user client. This was modified from a standard app to a daemon, following the advice here: https://developer.apple.com/documentation/xcode/signing-a-daemon-with-a-restricted-entitlement. However, it is the driver that crashes - not the host opening the user client.

Hi there. I inadvertently deleted the Passwords app. The App Store is telling me restrictions are enabled so I can’t reinstall from the cloud. Not sure where to go from here. Help.
