Hi there,

I am trying to build the Apple SimpleAudioDriver example but fail with codesign and/or provisioning.

I would be ok for now with the local option, but XCode 16.4 doesn't show the option "build to run locally" (SIP is disabled). When using "Automatically manage signing" it ends in a "Please file a bug report".

I found that having two different development teams tripped it up, so I deleted all certificates and keys and made sure to be only signed into one account in Xcode.

Can anyone give advice? Thanks a ton!

Here is the URL to the sample: https://developer.apple.com/documentation/coreaudio/building-an-audio-server-plug-in-and-driver-extension

macOS: 15.6.1 XCode: 16.4 Hardware: MacBook Pro M2 Max SIP: disabled

look in ~/Library/Developer/Xcode/UserData/Provisioning Profiles for the Xcode-generated profile. You can use QuickLook to inspect the profile. If you added the DriverKit USB (development) Capability, your profile should have idVendor='*'. This wildcard value will only work for development builds.

Your entitlements.plist should have an entry called com.apple.developer.driverkit.transport.usb or "DriverKit USB Transport' which is an array, containing one or more items, each of which is a dictionary. Each dictionary should have an item with key idVendor and value a decimal number equal to the vendor ID of the device you're driving.
