For the Horde
Note: This post is for WarCraft III-loving, Intel Mac-using friends. The problems here described are specific to our crowd.
If you’re like me, you’ve tried installing your old copy of WarCraft III and/or The Frozen Throne from the CD a dozen times, and every time you attempt to patch it to the latest version, something fails or gets corrupted and it just won’t run. The patch will happily break your WarCraft III.app over and over until you realize the patch is actually completely broken.
If you’re like me, you also didn’t realize that the easiest way to solve this problem is visit Blizzard’s Battle.net site, set yourself up an account if you don’t already have one, and register your CD key with the site so you can download an updated, Intel-ready copy (1.21b) of the game to install. You can then upgrade to the latest patch version without issue. The latest patch notes claim to fix “an issue where some patches could not apply on Intel Macs,” but in my experience the issues persist.
Just for reference.
