Leopard compatible applications

As with any OS release, there are bound to be problems with third-party applications. Before upgrading one of the things you must first do if find out whether your application under Tiger or Panther will run on Leopard (too many cats in this sentence). You should go to the developer's website and see what they have to say about compatibility with Mac OS 10.5. That can be a little tiring especially if you use a apps. Luckily for us, there are some helpful souls on the net that has documented what software is or isn't compatible with Leopard.

Mac Rumors Guides listed the applications that have major or minor compatibility issues with Mac OS 10.5.

Another resource is at Dommy's World. I guess Dommy has taken the time to browse through forums and listed down what applications are compatible and not compatible with Leopard. His last update was on October 31.

Again, before you stick a new cat into your Mac, find out first whether your installed third-party applications will play well with Leopard. If most of your apps don't work, better wait for a few weeks and then decide. By the way, the other first thing you should do before you upgrade is to backup, backup, backup.
