It seems that the cfgutil has problems in macOS 12 .
When running it, this error message is displayed:
objc: Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libamsupport.dylib (0x1f497b130) and /Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x1048c02c8). One of the two will be used. Which one is undefined.
objc: Class AMSupportURLSession is implemented in both /usr/lib/libamsupport.dylib (0x1f497b180) and /Library/Apple/System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x1048c0318). One of the two will be used. Which one is undefined.
This error output can destroy or interrupt an automation, so at the moment there is only the possibility of intercepting the error message.
For this, we simply forward the error message to /dev/null.
