Generating icons for Mac apps is tedious. And then, if you have a document based app you have to come up with a document icon. After having to edit, resize and rename my icons for the umpteenth time I decided to solve the problem once and for all, and produced McIcon.
Check the video on the support page to see how easy it is.
Give McIcon either one large image, or several images tailored to specific icon sizes, and itll let you export either individual icons or whole sets in correctly formatted .iconset and .appicon directories, which can them be dropped right into your Xcode project.
Given an app icon it can automagically generate a document icon.
This used to take me many minutes - now its a handful of seconds.
