Apple Configurator - Automation Tools

When running a cfgutil command I can verify across multiple OS versions, 10.15.7, and 11 that we get the following. 

% cfgutil get all

objc[2358]: Class AMSupportURLConnectionDelegate is implemented in both /usr/lib/libauthinstall.dylib (0x7fff8ad23a30) and /System/Library/PrivateFrameworks/MobileDevice.framework/Versions/A/MobileDevice (0x10681a8c0). One of the two will be used. Which one is undefined.

This message means that some classes (like AMSupportURLConnectionDelegate) are implemented in two different libraries, in this case both libauthinstall.dylib and the MobileDevice framework. In some cases this is just log noise, because the two classes are rev locked so it doesn’t matter which one gets used. In this case, however, MobileDevice framework isn’t part of the system (1) so there’s a (small) possibility that they might get out of sync in a way that causes problems. Given that, and the annoying nature of this issue in general, you should definitely file a bug about this.

Please post your bug number, just for the record.

(1) While the path shown by the message is in System/Library/PrivateFrameworks, which suggests it is part of the system, the actual framework resides in /Library/Apple/System/Library/PrivateFrameworks/.

We've been experiencing this for some time as well, from devices with Catalina to Monterey.

Also created a Feedback Ticket per recommendation: FB9766780
