Different results on my Windows vs Mac

[larsbopark]

On my Windows machine, it all runs fine and the key is found, and it is indeed the right key.
When I run it on my Mac I get the error:
[!] No match for the First_Byte_Sum (), is the card a genuine MFC Ev1?

I hope someone might have a good answer to why this happens, and maybe a fix too :)

Not working correctly on M1/M2 processors, not bug on our side. Proxmark3 has same issues (where I took all code)

A workaround is to use an x86 install of python (the system one should work) by running arch -x86_64 zsh then `

/usr/bin/python3 -m venv venv
source venv/bin/activate
python -m pip install FlipperNested
python -m FlipperNested
