Using IOServiceMatching and IOServiceGetMatchingServices api's written in swift to extract the info of both internal and external USB devices connected. For the same code Intel based Mac OS devices gives all the info like product id , vendor id , Serial number and etc for both external and Internal USB devices( Apple and Non Apple devices connected either to Apple T2 bus or USB bus). For the same code M2 Mac Machine only gives the external device info which are connected to USB, doesn't give any info of Internal USB connected devices. Why is this difference ? Which api's need to be used to extract info of internal USB connected devices even in M2 based Mac machine. Thanks

We have developed a library and a DriverKit driver on Mac platform. And we need to disable SIP to install dext and later point of time if we enable SIP then the dext is non functional. So is it mandatory to disable the SIP for whole life time of dext? Also it is not recommended to disable the SIP for a long time, as it may create a security hole. Standard ways are given on Apple support page that how to notarise an application to distribute over the internet. Here one mandatory account is required that is Apple Developer account which is a paid account we believe. Standing at this point can you share the complete steps of software distribution process which will include code signing, notarisation process and stapling.

Hi. I am new to ios development and I am using swift to try to develop a sample app to connect a Canon camera to an iphone via a usb cable and I want to use the ImageCaptureCore framework to do this (that is I want to use the USB PTP). Although I see the documentation on the Apple site, I am still unsure where to begin. Is there any tutorials, etc. about where I can get started with this? I was able to find a couple of code snipets and piece together something with ICDeviceBrowser but when I load the program onto my iphone and connect the camera via usb, I am not able to detect any camera. So ideally I am looking for some sort of tutorial that goes through how to do this or if not, what do I have to do to at least be able to detect the camera from the iphone?

Hi everyone, first-time caller, long-ti... wait, no, I just got here. :) I am relatively new to all things Apple, so apologies in advance if it takes me a few goes to properly explain things. We have a framework, which includes an API, an XPC service, etc, and we have a device driver. We also have some sample apps that use the framework, and if they have the app sandbox capability, then we expect them to use the XPC Service instead of accessing our driver directly. This works fine on Monterey and presumably has worked fine on all previous versions of MacOS. Something seems to have changed on Ventura, and we don't understand what. When we build the same app on Ventura, it appears to be in the sandbox (according to the Sandbox column in Activity Monitor), but in the Console there is this line (twice): default <time> <OurAppName> Revoking sandbox extension; key = 0 Which we suspect is linked to the fact that the app then does not use the XPC Service, and instead accesses the driver directly, much to our surprise. Software built on developer's machines is "Automatically managed" and "Signed to Run Locally" in case that matters. Do we need to change our code to support Ventura and onward? Or is it a bizarre bug? Oh, I should say that I'm running the latest version of Ventura (13.6.7 as of writing) but not the latest Xcode (14.2 (14C18)) and CLI tools... can't remember how to find that version... Apple clang version 14.0.0 (clang-1400.0.29.202). Any help would be appreciated, thanks. Jeremy

Hello. Is there a legal way to block iOS devices from being mounted on macOS? I noticed, that when an iOS device is connected, it pretends to be like a storage device but it is not. It not even going through diskArbitration. It seems that some fileProvider is taking place there. I know that it is possible to do via the MDM profile: <key>PayloadContent</key> <dict> <key>.GlobalPreferences</key> <dict> <key>Forced</key> <array> <dict> <key>mcx_preference_settings</key> <dict> <key>ignore-devices</key> <true/> </dict> </dict> </array> </dict> </dict> But is there some programmatic solution? If I use EndpointSecurity and block file operations for the usbmuxd process on /var folder, it prevents iOS devices from being mounted. But wouldn't be there any negative side effects from such a solution?

hi all. I subscribe the notify write event, every time I recieve a notify write event message i will send log data and reply block(didn't do nothing) with async method to host app(Objc XPC API).host app will reply immediately once it recieves data. after a while my sysext crashed, then I checked system log find the log below. launchd: exited with exit reason (namespace: 30 code: 0xc40000000004aaaa) - (unknown reason) is it because of exceeding the maximum limit of xpc's block queue length, or too many memory allocation, or... by the way, host app didn't crash. how this happened exactly? how could i solve it?

I have a USBDriverKit driver which tries to send vendor-specific DeviceRequests to the IOUSBHostDevice. A few short months ago this worked, and as far as I know, the only change since it last worked is an update to macOS 14.5. The dext user client calls through to the driver, which wants to do this: ivars->mDevice->Open() ivars->mDevice->DeviceRequest() ivars->mDevice->Close() the problem is that the call to Open returns 0xe00002cde, which is kIOReturnNotOpen. If I don't call Open, but simply call DeviceRequest, I get the same result, kIOReturnNotOpen, which I would expect. I'm pretty sure that in macOS 14.4, the call to Open() did not return an error. I haven't seen any system logs that clue me in to why Open() is failing. It would be handy if the error gave me some reason why the device cannot be opened. Has anyone else seen this? I've searched high and low and I can't find any examples of dexts which actually do anything at all with a USB device.

Hello, forum, I'm trying to build connection between a non-MFi HID device (like keyboard) and iOS app with IOKit and Swift. Thanks to this post, I have manage to import the IOKit into objc header. IOKit on iOS/iPadOS 16.0+ #import <IOKit/IOKitLib.h> However, I have this compiler error when I try to imitate same methods in the SerialPortSaple project from following article, but the IOKit can not be imported to Swift at first place. Communicating with a Modem on a Serial Port The screen shot of the sample project: It looks like the complier unable to reach the io_object_t type somehow, is there any workaround or approach?

Hello forum, I'm trying to build communications between a non-MFi HID device (say, a keyboard with a USB-C port) and an iOS device over a MFi-licensed cable with Swift, what framework would you suggest? The USB-C cable is MFi-licensed. The keyboard is not MFi-licensed.

I use NETransparentProxyProvider transparent proxy the outbound data ports 80 and 443, at the same time using CocoaAsyncSocket third party open source libraries for data forwarding At first, handleNewFlow will be called normally, but after running for a period of time, handleNewFlow will not be called again, and the system will not be able to access the Internet unless the vpn is disabled By checking the terminal app log, I found that handleNewFlow will not be called again when the following information is displayed. # Domain=NEAppProxyFlowErrorDomain Code=1 "The operation could not be completed because the flow is not connected" UserInfo={NSLocalizedDescription=The operation could not be completed because the flow is not connected" #

Where do I get. PerfPowerTelemetryClientRegistrationService which is suddenly missing from my system since upgrading to MacOS15/IOS18?

I'm trying to make an asynchronous bulk data read using AsyncIO/CompleteAsyncIO. The problem I'm facing is that the AsyncIO succeeds but CompleteAsyncIO/ReadComplete doesn't get called when the AsyncIO's completion timeout is set to 0. Changing the completion timeout to a non-zero would trigger ReadComplete but I keep getting the (0x2d6) "I/O Timeout" error Any idea what I'm doing wrong? Also, is there any limit for the maximum buffer length the callback can accept? Thanks. struct MyDriver_IVars { OSAction* callbackAction = nullptr; // registered callback action by app IOUSBHostInterface* interface; IOUSBHostPipe* pipe; IOBufferMemoryDescriptor* inDataBuffer; OSAction* ioCompleteCallback = nullptr; // read complete callback action uint32_t MAX_LENGTH = 1024; }; kern_return_t IMPL(MyDriver, Start){ //........... ret = ivars->interface->CopyPipe(endpoint->bEndpointAddress, &ivars->pipe); ret = ivars->interface->CreateIOBuffer(kIOMemoryDirectionInOut, ivars->MAX_LENGTH, &ivars->inDataBuffer); ret = CreateActionReadComplete(ivars->MAX_LENGTH, &ivars->ioCompleteCallback); //........... } kern_return_t MyDriver::ReadData(int nbytes, int timeout) { //........... kern_return_t ret = ivars->pipe->AsyncIO(ivars->inDataBuffer, ivars->MAX_LENGTH, ivars->ioCompleteCallback, 0); //........... } void IMPL(MyDriver, ReadComplete) { Log("ReadComplete() - status - %d; bytes count - %d", status, actualByteCount); //AsyncCompletion(ivars->callbackAction, .................. } virtual void ReadComplete(OSAction* action, IOReturn status, uint32_t actualByteCount, uint64_t completionTimestamp) TYPE(IOUSBHostPipe::CompleteAsyncIO);

Bjr. Je ne parviens plus à réinstaller aucune application après avoir formaté ou réinitialisé mon iPhone. Comment résoudre se problème rapidement. mon système c'est IOS 17.5.1. Peut être faut-il faire une mise à jour du système pour résoudre définitivement ce problème d'installation d'applications. sil vous plaît trouver une solution rapidement. Je veux récupérer mes données d’urgence. Merci

I'm trying to communicate with an RS-485 device using a USB-to-RS-485 adapter based on a CP21012N. It's capable of speeds up to 3 Mbaud. However, when I call tcsetattr() with speed set to anything other than one of the predefined constants (using cfsetspeed()), I get an "Invalid argument" error back from the call. Googling, I found https://github.com/avrdudes/avrdude/issues/771 Seems like macOS really can't accept baud rates outside the predefined set without resorting to ioctl?

Since the day i updated ios18 developer beta, screen time stops working and it wont let me access my apps under screen time lock despite of entering right password. Urgent solution required asap. please do something

I'm trying to make an asynchronous bulk data read using IOUSBHostPipe AsyncIO/CompleteAsyncIO and send the data back to the user-space application using AsyncCompletion. virtual void AsyncCompletion(OSAction *action, IOReturn status, const IOUserClientAsyncArgumentsArray asyncData, uint32_t asyncDataCount); My understanding is that the IOUserClientAsyncArgumentsArray asyncData in AsyncCompletion method has a limited size of 128 bytes, and the data I need to send back is over 10k bytes. Would it be possible to send such large data from the driver to the user-space application using async callback? Thanks

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.

The situation: 1A) On last week our development team applied on-line for three idVendors with the format as the following: USB-VendorID: 547h(1351), 3488h(13448),4B4h(1204) Describe your apps: it shall be functional equivalence of existing Android-SDK for X-ray sensor-models:...with 15..25 text lines of the description below 1B) We received auto-reply, that we granted all the the entitlements. We've expected to have entitlements like approx like the these: &lt;key&gt;com.apple.developer.driverkit.transport.usb&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;idVendor&lt;/key&gt; &lt;integer&gt;1351&lt;/integer&gt; &lt;/dict&gt; &lt;dict&gt; &lt;key&gt;idVendor&lt;/key&gt; &lt;integer&gt;131448&lt;/integer&gt; &lt;/dict&gt; &lt;dict&gt; &lt;key&gt;idVendor&lt;/key&gt; &lt;integer&gt;1204&lt;/integer&gt; &lt;/dict&gt; &lt;/array&gt; 1C) Unexpectingly (for us) ASCII-strings-fragment from our iOS-target-binary "com.rayence.dexta.driver" (built with automatic signing; seemingly this shall be our actual granted prvisionintg profile) looks as the next: &lt;plist version="1.0"&gt; &lt;dict&gt; &lt;key&gt;com.apple.developer.driverkit&lt;/key&gt; &lt;true/&gt;&lt;key&gt;com.apple.developer.driverkit.transport.usb&lt;/key&gt; &lt;array&gt;&lt;dict&gt; &lt;key&gt;idVendor&lt;/key&gt; &lt;string&gt;*&lt;/string&gt; &lt;/dict&gt;&lt;/array&gt; &lt;/dict&gt; 1D) Repectively, now we shall specify (in our dext's entitlements in XCOde-project) &lt;key&gt;com.apple.developer.driverkit.transport.usb&lt;/key&gt; &lt;array&gt; &lt;dict&gt; &lt;key&gt;idVendor&lt;/key&gt; &lt;string&gt;*&lt;/string&gt; &lt;/dict&gt; &lt;/array&gt; In DExt's info.plist we have "normal": &lt;key&gt;IOKitPersonalities&lt;/key&gt; &lt;dict&gt; &lt;key&gt;IOKitPersonality_EzHD&lt;/key&gt; &lt;dict&gt; blah-blah &lt;key&gt;idVendor&lt;/key&gt;&lt;integer&gt;1351&lt;/integer&gt; &lt;key&gt;IOKitPersonality_EzR&lt;/key&gt; &lt;dict&gt; blah-blah &lt;key&gt;idVendor&lt;/key&gt;&lt;integer&gt;131448&lt;/integer&gt; &lt;key&gt;IOKitPersonality_EzR&lt;/key&gt; &lt;dict&gt; blah-blah &lt;key&gt;idVendor&lt;/key&gt;&lt;integer&gt;1204&lt;/integer&gt; blah-blah Our ambiguities: 2a) Without exact "1D)", our DExt-installer-application never starts in iPAD. OS-loader generates obectievly-meaningless error-messages and seemingly-meaninglessly suggest to look "system-logs" (which seemingly don't contain relevant information) 2b) With exatct "1D)", 2ba) the reaction (presence/absence and timing of relevant console.app's messages) of our iPAD 17.4 on plugging/unplugging our gadgets look "non-logical". It isn't completly wrong but suspicious. E.g. our Swift-module randomly receive/dontreceive relevant events and can't connect communicate driver's instance for newly-attached physical gadgets. We realize, thses it could be our bugs; but we need disambiguation to debug the issues (or at least to be sure that the quirks are like in production system). 2bd) we would prefer debug/develop rather with real "idVendor=number nnn"s in provisioning profile (than with "idVendor=string *"). So we could be sure that quircs "2ba" are like in a production system. Respective question: Which format in on-line application ~1A) shall we use to obtain provisioning profile 1B)
