Apple provides a simple way to call the default “About Panel” to display copyright information and another kind of legal/license/… related information. It takes the information available in the Info.plist1 of your application and shows them:
The thing is that you can add your own custom text to it as well. It’s really easy, you just need to add a file named
Credits.rtf and Xcode will add it automatically above the copyright message. There is a caveat though: The file needs to be created from inside Xcode, I tried creating it both from Xcode -> Create New -> Empty File and from an external text editor and Xcode wasn’t able to read those file even after importing them.
So here’s what you need to do:
- Create a new file with Xcode (CMD+N)
- Select OSX - Resources
- Select Rich Text File and name it “Credits”
- Make sure to include your application as a target as always.
Now you can add anything in there (I added a link for example and it’s fully clickable).
You used to be able to call it “Credits.html” before OSX 10.10 and include HTML code in it, but now it doesn’t seem to work anymore. Not to bad since it still parses links though and since it’s an RTF you can change text color and everything.
