I have seen a few people experience difficulties installing ColdFusion MX 6.1 on OS X. Not to worry — it works fine. You just have to make a few adjustments.
The problem people seem to be running into is with the graphical installer. There seems to be an issue with the graphical installer and Sun’s 1.4.1 JVM for OS X. There are two ways to fix this:
Run the installer in console mode like this:
% java -jar ./coldfusion-61-other.jar -i console
(Don’t actually type the “%” — that is meant to represent your command prompt.)
This is not as scary as it might sound. The console installer is just as user friendly as the graphical version, except for the fact that you have to type paths in rather than navigate to them.
Run the graphical installer with Java 1.3.1 rather than 1.4.1. This is perfectly safe and doable on most configurations since the OS X software updater does not remove the old version of Java when installing the new version (rather, it installs the new JVM right along side the old one and simply changes some symbolic links).
Here is the command for running the graphical installer with Java 1.3.1:
/System/Library/Frameworks/JavaVM.framework/Versions/1.3.1/Home/bin/java -jar ./coldfusion-61-other.jar -i gui
The command above may have broken onto two lines in your browser — make sure you run it as a single line.
