Installation on macOS (M1) fails

I tried to install pyOCD as part of the Zephyr SDK on my Mac Mini M1. However, I'm facing an issue:

No matter if using the zephyr installer command west packages pip --install or use pip install pyocd, pip install --no-binary capstone pyocd or python3 -mpip install -U pyocd, the installation always fails with:

Would be happy if someone can help me out, thanks.

Start with the reported capstone build output, especially the macOS M1 linker error involving -soname and the missing libcapstone.4.dylib. Trace how pyOCD installs capstone through pip and determine whether installation can complete on this platform; done means the documented installation commands succeed.
