Although my true love is the second game, Shadows of Amn, it hasn't been easy to find for Mac's updated systems. The thing that impresses me is that there are enough Baldur's Gate fans to make doing an updated version financially viable. It's been around for a long time.
Why dwell on this now?
Because there is an enhanced version of the original Baldur's Gate and the Tales of the Sword Coast expansion pack (which I never had) coming out very soon. With more characters and extra quests.
AND (because that's not enough ... it never is) there will be a remake of Baldur's Gate II: Shadows of Amn and the expansion, Baldur's Gate II: Throne of Bhaal.
AND (because even that is not enough) there is a plan to make Baldur's Gate 3 after both enhanced editions are done. Of course this depends on how well these other remakes do.
I am willing to do my part. Just get that Mac OS X version out there and I will buy it.
