5.0.0 & 5.0.1 do not install in python 3 on macOS (cannot load dynamic library)

[gerph]

Following on from https://github.com/capstone-engine/capstone/issues/2145...

@gerph I know you are aware of it, but as a general note: Because Python2 is EOL we removed the CI code for it as well. So there is no guarantee that it will work in the future.

So I tried installing 5.0.0 and 5.0.1 on macOS 10.14.6 (which is presumably supported by the universal wheel) with Python 3.9...

Have you tried pip install --pre --no-binary capstone capston (as suggested in https://github.com/capstone-engine/capstone/issues/2066)?

Can't test it myself, don't run a Mac unfortunately :(

Just got a Apple Silicon Macbook for fixing this. This issue will be fixed in next release.

And for now, plz using pip install --pre --no-binary capstone capstone.

Ah yes, I'm running on an old intel macbook - sorry, I keep forgetting that it's important to mention the architecture whilst Apple have two different systems.

And to confirm - yes, if I use that command line to install with Python 3, all is well. Thank you :-)
