It has been an eternity (well more like 5 years), but we have released a new AOL client for the Mac. The client will run on both MacTel and PPC for Leopard and Tiger.
So far the reviews have been very good for this application, so if you are a long time AOL user on the Mac check out the latest build.
One thing about this client that is worth pointing out is the buddy list and IM functionality in the client is powered by the Open AIM Mac SDK. The Mac SDK contains framework for applications to be written using Cocoa. This framework is the same that powers our experimental AIM Lite client for the Mac that we released in January of this year. You can view the source for this experimental client in the Mac SDK. We are starting to see more applications being written for platforms other than Windows which is really exciting.
I know the AOL Mac team would love to have some feedback on their work. They have a blog where you can keep up with the latest info and where you can share your thoughts on the client.
