Get IDEA 3.0 running on OS X

IDEA 2.6 runs out of the box on OS X, but who wants that when the Windows and Linux people are enjoying the truckload of 3.0 features.

Here's how to get IDEA 3.0 running on OS X:

1. Get OS X 10.2.2
2. Get JDK 1.4.1 Developer Preview 6: Sign up for the free Apple Developer Connection. Then login and go Download Software > Java > Java 1.4.1 Developer Preview 6
3. Get IDEA 3.0.1 (build 688)
4. Create a symbolic link to JDK: Go to the directory you unpacked idea688.tar.gz in and create a symbolic link to JDK 1.4.1. With the terminal in the IDEA dir: ln -s /System/Library/Frameworks/JavaVM.framework/Versions/CurrentJDK jre
5. Run IDEA 3.0: From the terminal in the IDEA dir run "bin/idea.sh".
6. Get a evaluation key (optional): Fill out the IDEA evaluation form and wait a few minutes.

Please note that IDEA on OS X use CTRL+C/V for copy'n'pasting (instead of COMMAND+C/V). This is especially frustrating to forget on the license screen. All other hotkeys are CTRL-based as well. Hopefully IntelliJ will conform to the standard Apple way of hotkeys in the future somehow.
