Also you may have problems with Warcraft 3.
Blizzard have posted this for OS X 10.7 Support:
This summer, Apple is scheduled to release Mac OS X 10.7, Lion. Due to certain changes in the Mac operating system, StarCraft, StarCraft: Brood War, Diablo II and Diablo II: Lord of Destruction will not run on Mac OS X 10.7. While these titles should still technically be able to operate under Boot Camp, we will not be able to provide support for these titles running on Mac OS X 10.7. For more information about Mac Boot Camp, please see Apple's website: http://www.apple.com/support/bootcamp/ We will continue to offer support for these titles running on Mac OS X 10.6 and below.
At this time, we expect Warcraft III to run on Mac OS X 10.7. However, the updater that we use to apply patches does not work on Mac OS X 10.7 natively, so while a patched-up version of the game will work, you will be unable to patch up to the latest version of the game when running Mac OS X 10.7. We don't currently have a timeline available for when we may be able to release updated patches with a compatible Updater program.
We’ll have more details for our Mac community as Lion's release date draws nearer.

StarCraft - Blizzard Shop. Warcraft III: The Frozen Throne adds a host of new features to the game, including four new campaigns that take you across the frozen continent of Northrend. Explore new maps and master new units such as the Troll Bat Riders, the Blood Elf Spell Breakers, and the destructive Mountain Giants.
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.
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.
If you have any errors please read the steps again.
