This is a follow up on my older blog post „How to configure Apple Airport Express 1st Generation on Mountain Lion„. The situation is the same: I’ve wanted to configure my fathers Airport Express 1st Generation. However, we both updated to Mac OS X Mavericks 10.9 and where unable to use the Airport configuration utility I’ve created in my aforementioned blog post.
Looking online for a solution to this problem, I’ve found this blog post which provides you with a running Configuration Utility. Corey did also an analysis why the older Utility was not running anymore: The Utility relies on a library which broke backward compatibility in Mavericks.
