It works fine on Intel Macs, but on MacBook Air M1 something seems to be broken...

/Applications/Viscosity.app/Contents/MacOS/viscosity_openvpn --show-pkcs11-ids "/Library/OpenSC/lib/opensc-pkcs11.so" works fine and shows the certificate info

Hi darhipov,

You appear to be using a PKCS#11 driver, which is OpenSC in this instance. You’ll need a build of OpenSC with native Apple Silicon support.

The OpenSC project has added support for Apple Silicon, but it appears they have not yet made a new offical release available. However, you can download a “nightly” build from them with support:
https://github.com/OpenSC/OpenSC/pull/2 ... -790550890

It appears an offical release, version 0.22.0, is likely due for release in a couple of weeks time:

Cheers,
James
