I really have no advice to proffer apart from, "don't buy mac"
We're not trained, nor are we professionals, and we're most certainly not part of the games industry; This is just a hobby project for both me and mike.
We know the mac version needs a lot of love, we know it'll work if teased a bit- but we also know that's beyond the skill level of a lot of our users.
The fact of the matter is, neither I nor anyone else on the development team have a mac or know anything about building and packaging things on there, and that probably won't change without a $2000 investment none of us can afford, let alone care to.
Let's see... your options are basically as follows...
1. Give up
2. Compile a mac binary for the desired game module.
3. Use wine (there's a commercial variant called crossover) to run the Windows version on your system, there's some overhead but it works really well.
4. Install a Linux distribution such as Debian or Ubuntu inside a virtual machine (macs come with parallels) and run sandbox through there
5. Install another operating system (like Linux obviously) and run their respective native version, macs apparently have something called "bootcamp," so look into that.
