Update for Mavericks:
Warcraft 3 The Frozen Throne will not work on Mavericks. NEVER!
The reason is simple. WC3 was build for Power PC (old macs without intel cpus) and Apple dropped another bite of Power PC Support in Mavericks. You couldn’t install or update wc3 on the last few Mac OS X versions, now on Mavericks you cant connect to the battle.net or LAN. Apple dropped support for „Open Transport for networking“ which was used by wc3. So there are 2 solutions for this problem.
Apple adds Open Transport again, which will never happen!
Or Blizzard rewrites wc3 for the new Mac OS X plattform, which will never happen!
So you won’t be able to run wc3 (dota) native on a Mavericks or newer!
If you want to play Wc3 Frozen Throne (Dota, …) on Mac OS X Mountain Lion you have to do some steps, because it won’t work after the update.
1) You can’t install Wc3 on Lion or Mountain Lion
The install app from Blizzard is old and for Power PC only. Mac OS X Lion and Mountain Lion don’t support this type of applications anymore. You also can’t update to a newer version of Wc3, because the updater app is also for Power PC only.
You have to install and update Wc3 TFT on and older version of Mac OS. For example Snow Leopard. Then copy the „Warcraft 3 Folder“ to Lion or Mountain Lion.
2) You can run Wc3 but not The Frozen Throne on Mountain Lion
3) You should be able to launch Warcraft 3 The Frozen Throne now.
