Simple free diff tool for Mac OS X 10.5: Kdiff3

I needed a diff tool to compare text files on my Mac, and it turned out to be a time-consuming endeavor to find a basic free diff tool. One option is to install the Mac developer toolkit Xtools, but if all you need is the diff tool, why would you want to install 750MB worth of other tools you’ll never use. Plus, first you have to sign up for a free developer account, and if you are not on the latest Mac OS version, good luck figuring out how to find the Xtools version that works with your OS. I downloaded Xtools only to realize that I wasn’t able to install it afterwards because I am still on Leopard (10.5). I then looked again for free tools and found an app called mend which I couldn’t figure out how to download from the site, plus  it needed Fink installed first (so I got stuck again…).

I was successful with my next try. And the winner is: Kdiff3 (Kdiff3.sourceforge.net)! Simply downloaded it and double-clicked the app file. Took me nothing but 3 minutes. Nice.
