Oh yeah. The MacOS is something magic you’ve worked out. I use my yubikey for ssh keys and I was never able to figure out how to get macOS to work for other processes (like IntelliJ) unless it was started from a shell. Then one day IntelliJ changed how that works and it hasn’t worked since.

Anyway, this is really cool. I use Windows, Linux, and Mac every day for work and having a consistent method of doing this kind of stuff sounds amazing. Keep up the good work.
