According to you need ports 6881-6999 open for peer to peer traffic. Make sure your computer and local routers have these unblocked (or at least, properly forwarded). Most routers also have a 'DMZ' option for computers, which you can temporarily place your computer in for unrestricted access to the internet. Search Google for 'your router name DMZ' to learn how to enable this. Unfortunately, these are common bitTorrent ports and your ISP might be throttling or blocking these ports. If you go to View Connection Info in the downloader you can see where the problem lies.
Repeat the steps above for each port you need opened based on the above table. Your firewall should now allow traffic on the necessary ports for proper Blizzard Downloader The firewall in Mac OS X and macOS allows you to control connections on a per-application basis, rather than a per-port basis.
Most likely only the 'Direct Connections' are available and no other 'peers'. Your best bet in this case would be to copy the client from a friend who has downloaded it, change your internet service provider or use a proxy.
I had this same problem, and while your question asks specifically with how you open ports, which I think the other answers do a good job describing, that didn't actually result in faster download speeds for me, and based on some comments you left it sounds like it didn't work for you either. The following, however, did work wonders for me:. Open up Internet Explorer (whether it's your main browser or not). Go to Tools - Internet Options. Click on the Connections tab. Click the Lan settings button.
Uncheck the 'Automatically detect settings' checkbox. Restart your Blizzard Downloader. (possibly unnecessary) After doing this and restarting the downloader, I suddenly went from truly abysmal speeds (like, 100 MB downloaded over 3 hours) to a 800 KB/s transfer rate.
Even with P2P disabled (and thus, I think, not even needing the port forwarding) I was getting these speeds. Everything else I'd tried before this, such as forwarding ports, disabling the firewall, turning off anti-virus, or enabling/disabling P2P had no effect on my actual speeds.

IMHO, Steve Jobs put the Intel chips in Macs because, not only are they better at power/wattage usage but, since not many games were being released for MacOS, it is easy for Gamers to just put Windows on the machine and game from that. Not to mention many people can use a boot-window to run their DOS/Windows program in as well (without any emulation). I guess you can go to Blizzards Social Media and vote for Mac OS versions of games. I think it will also depend on how Apple handles their new 'modular' Mac Pro. Will 'base units' start at $999 that you can easily game on and upgrade from there? Or will it still start at their premium $3000+ thus, really, killing off the notion that Macs are 'gaming' pc's.
Who really wants to game on an iMac?
