Icon Glue is probably the easiest way to quickly create an Apple Icon Image (.icns) for your mac app from a single 1024x1024 pixels sized PNG or TIFF image.create .icns files or .iconset image sets from a single PNG file
You can also create all iOS app icons you need for submitting apps to the App Store in just one go.
Just open your image, select what you want to create (Icon Glue will remember these settings) and save it. You can also open an OS X application bundle to easily extract its icon without having to browse through the bundle's internal folder structure.
Icon Glue can ...
create the iTunesArtwork.png images required for app submissions on the Mac App Store
create all app icons for your iOS apps
extract all image representations from an existing .icns file
extract an application bundle's icon and export it as .iconset and/or PNG file
show previews of all iOS and OS X Icons to be created and allows you to save them one at a time
Rectangular (non-square) or too small images will be adjusted accordingly to ensure that the result is always a valid, retina-compatible .icns image file.
