Summary

Do this PR after: #1686, as that PR is to merge into this branch (my mistake).

Fixes a few issues on my Apple Silicon MacBook

[1] Capsule hand sphere mesh was not set in the prefabs, generating errors. Not sure why this is only seen on a Mac and not in Windows,
[2] Binaries for Apple Silicon were not present and/or signed. Added these.
[3] Improved some error handling.

These changes look good to me, however why are the dylibs including -2 suffixes?

[MaxPalmer-UH]

I've tried to tidy up the libs / names. This appears to work on the Apple Silicon Mac I have but I'd appreciate someone else checking it works on theirs. Unity does some caching of the binaries sometimes.

Can we not lipo a single dylib for both architectures?

[MaxPalmer-UH]

I originally went down that route with Peter and it seemed to become more complex than you might imagine...

[rblenkinsopp]

Happy then if alternative routes have been investigated.
