Hi @MdAbuNafeeIbnaZahid, unfortunately I didn't. I had to add a switch in my application to ignore m2crypto when I'm doing dev on my Mac, i.e.

try:
    from M2Crypto import SMIME, X509, BIO
    CRYPTO_LOADED = True
except ImportError:
    CRYPTO_LOADED = False

Getting the following error on Mac OS 11.1 (Big Sur):

Nice is work, thanks

perfect！！

it works for me, thanks.

If you accidentally (or purposefully) you have another version of OpenSSL these are the correct commands:

brew install openssl@1.1

env LDFLAGS="-L$(brew --prefix openssl@1.1)/lib" \
CFLAGS="-I$(brew --prefix openssl@1.1)/include" \
SWIG_FEATURES="-cpperraswarn -includeall -I$(brew --prefix openssl@1.1)/include" \
pip install m2crypto

 include/sys/_types/_int8_t.h:30: Error: Syntax error in input(1).
    error: command 'swig' failed with exit status 1

You need to make sure a real gcc (not /usr/bin/gcc, which is clang) installed. Otherwise it uses clang to build the package.

_m2crypto.so' (mach-o file, but is an incompatible architecture (have (x86_64), need (arm64e)))

Any solution?

Worked for me (Intel Mac Ventura, openssl@3). I set the environment and to get the right Python I used python3 -m pip install m2crypto
