I forgot to mention that also, of course, CoolKey is open source and the CoolKey PKCS#11 module supports the CoolKey applet (obviously) and makes some attempts to support the US DOD CAC and the US Government PIV -- though I don't know how successful they are. Bugs and feature limitations in CoolKey led me to write CACKey.

Coolkey is trying to link OSX 10.5 libraries and cross-compile for PowerPC. Seems like abandonware. Are you using it successfully in 2020?
I mostly use CACKey, since I wrote it to replace CoolKey for my needs.
The PIVKey C910 complies with NIST SP-800-73 (PIV) -- same as YubiKey PIV mode, so OpenSC supports it. Also, the middleware I wrote (CACKey) is open source and supports it and works on macOS as a tokend driver.
>Windows In-Box PIV Driver (Read Only) and PIVkey Windows Minidriver (Read/Write): Windows Vista, 7, 8, Server 2003, Server 2008, Server 2012.
>Mac OSX, Linux and Android (Read Only - Middleware Required)
The only open source middleware I know of for OSX is OpenSC, and it doesn't list C910 as a supported card.
