MacOS Error when signing SAML Response

Question

Hello When we use the Q2SamlResponse class and run the sign function with our cert on a Mac computer we get the following error q2 sdk models saml response MacOSError A recent update to MacOS has issues with the xmlsec library We tried updating that package reinstalling it everything but still get the issue We are using SDK v2 266 1

Unfortunately it s more complicated than that xmlsec itself depends on libxmlsec1 which is a C library These can either be compiled to order or pulled as precompiled wheel whl files for python based on each operating system On Friday I uploaded precompiled wheels for all the mac xmlsec lxml versions I had access to and reuploaded them Even so there s is a segfault potential in the xmlsec package on modern mac versions As such since 2 266 1 rather than segfaulting we try multiple times in a subprocess to sign the XML then if after 10 tries it never works we throw this error I recommend pip uninstall xmlsec then pip install xmlsec no cache as your best bet If you have an alternative that involves a less segfaulty solution on Mac I m all ears This particular bug has been quite the frustrating one on the internet boards
