FYP
And to the powers that be who might be considering developing such a solution... I'd easily pay $20, $30, or even $50 for a sound/stable/reliable program or app. I'm just sick of the unreliable, buggy, and glitchy crap that's out there.
If you haven't tried it yet, I'd still suggest DDPoker (http://www.ddpoker.com/download). It claims to run on Mac, although I haven't tried it myself (I don't have a Mac). I have used it without issue on Win10 and Debian Linux.
Is it pretty? No. But if you can get it to run on the Mac, it meets the rest of the requirements listed in the first post.
