A few days ago, I believe.

In other words, the mac version is here already and the game is currently discounted. Why not get the game now?

(Unfortunately, still no linux version.)

Where? Store page says only compatible with Windows 7,8 and 10?

In my library, there is an option to download the Mac version, even though it's not listed on the store page. (Bug or outdated store page?)

Edit: Apparently, it only has a 32-bit Mac version, and therefore won't run on newer Macs so isn't advertised, so I don't know if buying it will get you that version. (According to a reply to a post I just made in the "what did just break" thread)

I have read that the game is available on Steam. I was an early backer of Bard's Tale IV, but opted for the GOG key instead of the Steam one. I'd love to play this on my Mac. If Steam has a version that works on the current MacOS surely GOG will be getting it soon ?
