The desktop version of Yubico Authenticator (yubioath-desktop) allows for storing TOTPs on YubiKeys in Linux and OS X, too.
I like having TOTPs stored this way, as you can use them with any device, including over NFC on Android, just by installing the Authenticator app.
Interesting! Any suggestions for us Mac-inclined desktop users?

1Password for Mac allows you to do this also.

The desktop app will let you scan QR codes that appear on screen. When 2FA fields show up, the password autofill shortcut (cmd + \ is the default I think) will automatically populate them.
They can also use WinAuth https://github.com/winauth/winauth
Or for Linux you can use https://github.com/paolostivanin/OTPClient
