I created a simple way to install the Property List Editor DevTool with or without Xcode installed.
Watch this. It also has a download in case you don't wanna get the whole Xcode package. It's free and simple.
I'm new to he forums so please go easy on me. dx
I just came in to say that I followed the instructions and it worked like a charm. I had installed XCode 3.2.6 some time ago, in order to gain back the Property List Editor tool (since it is such a pain waiting for XCode to open and then navigate through it just to look at a PList). I believe I did this back when I found out they took it out from XCode 4.
However, this meant that I had multiple copies of XCode, of which one was specifically for a single tool. I followed the instructions as noted, except that instead of extracting the files from the downloaded package, I just used the ones from the older installation in the "/Developer-3.2.6" folder.
I re-associated the plist file types with the "Property List Editor.app" in its new location, and everything works as I wanted.
Note that I am not a developer (well, not any more), and I've only kept up with XCode for some of the tools that allow me to manage my system, including the "Property List Editor.app".
A big "thank you" to all of you for the assistance!
