I had the identical problem trying to use dylibs installed by Mac Ports. At runtime dylib wouldn't load the dylibs, saying: "code signature in '/opt/local/lib/opencv3/libopencv_shape.3.4.16.dylib' not valid for use in process: mapped file has no Team ID and is not a platform binary." The solution for me was to disable "Enable Hardened Runtime", which had been set to YES.

iOS 17.4 beta was just released. How can I try this out on my iPhone if I can't sync it with a computer? Is there a way to tell System Update to permit beta updates, or is there perhaps a direct link to the beta file?

Okay, my iPhone is now running iOS 17.4, and my macs are now running Sonoma 14.3. The iPhone appears in Finder & Music, I click on Trust (on both the Mac and iPhone), and the Finder just spins and spins and spins... What could be the problem??
