问题 I built a codeless DEXT to replace a working codeless KEXT - Migrating a codeless KEXT to a codeless DEXT. I referenced a few sites and GitHub repositories to put it together and had help from other SO users. I am running with SIP turned off, developer mode is on (systemextensionsctl developer on). I am following the advice outlined here https://github.com/knightsc/USBApp/issues/1 for signing the app and dext. When I run the app it is embedded in and request activation for the extension, that

问题 I'm trying to migrate from KEXT to DEXT. My USB device should not be matched by the classic driver (in the other case, it does not allow to open the device and interface). I am using a sample USB application for testing. So, before installing the system extension, I was able to see 1 device and 3 interfaces. However, when I install the system extension (next), I can not find any interfaces. They seem to be lost. To search for interfaces I use the command “ioreg -lirc IOUSBHostInterface”. Any

问题 I am working on migrating a codeless KEXT to DriverKit. It is used to disable the IOKit HID driver for USB devices that present themselves as HID compliant in firmware upgrade mode. So far I have managed to match an empty subclass of IOService to the relevant devices. Here's an example of the IOKitPersonalities entries I'm using: <dict> <key>CFBundleIdentifier</key> <string>$(PRODUCT_BUNDLE_IDENTIFIER)</string> <key>CFBundleIdentifierKernel</key> <string>com.apple.kpi.iokit</string> <key

问题 I am migrating a codeless KEXT to a codeless DEXT. I have watched the WWDC video and read much of the information on the Apple Developer site. The difficulty I am having is finding not what to do but how to get started. A nice tutorial with an example project would help. In my codeless KEXT, for 4 separate devices I have IOKitPersonalities for IOUSBDevice and IOUSBInterface for each device. The KEXT allowed me to match my devices to my "driver" so the Apple HID driver wouldn't grab them. I

问题 I tried to add virtual usb device with driver in Mac OS programmatically. IOKit documentations says: Traditionally, drivers of virtual devices match on IOResources because virtual devices do not publish nubs of their own. Another example of such a driver is the HelloIOKit KEXT (described in “Creating a Device Driver with Xcode”) which matches on IOResources because it does not control any hardware. But I don't found way to add virtual device in system. How can I do that? 回答1: What are you

问题 I'm trying to uninstall Parallels completely from macOS High Sierra. I removed everything from the disk except some Parallels extensions that are stored under /Library/StagedExtensions/Parallel Desktop.app I think the location has to do with user approved extensions, but I'd like to find a way to remove/uninstall those too. If I try to delete the extensions it says operation not permitted despite the root rights. Any idea? 回答1: There is new way to clear the StageExtensions folder as following
