Mac OS X Leopard only: If you tried installing our favorite password manager for Mac, KeePassX, on Leopard, you already know it doesn’t work. (When you launch it, it crashes immediately.) Someone who knows more about KeePassX than we do figured out it’s a problem with the out-of-date Qt development package installed with KeePassX. Luckily you can fix the problem with a Qt installation and a single command in the Terminal. Here’s how to get KeePassX working on Leopard.
Download and install the open source edition of Qt.
Once that’s done, in the Terminal, run this command:
rm -rf /Applications/KeePassX.app/Contents/Frameworks
When you launch KeePassX, all will work as you expected. You run into any other Leopard incompatibilities? Tell us about it in the comments.
