ANSWER:

If you have a recent MAC with an Intel CPU (anything since ~2006), you should just simply grab the proper (32 or 64-bit) version and that’s it.

In case you sport an older Mac computer (with PowerPC), you can grab the PowerPC images from the mirrors. Like from Germany.

But I’m pretty sure you have an Intel machine.
