You are correct that this is a particularly sucky moment for IF tools on the Mac. (As of MacOS 10.12.)
I have a working build of Gargoyle in this thread: https://intfiction.org/t/suggestions-for-the-game-of-the-month-september-06/74/1

Lectrote uses Parchment, which should support all Z-machine version 5 games… as far as I know. (I just stuck it in there, I didn’t test it widely.) Which games aren’t working?
