Making App Icons for OS X

According to Apple’s iOS Human Interface Guidelines, every app must provide an icon to be displayed on a device’s Homescreen and in the App Store. An app should specify several different icons of different dimensions to suit different screen sizes and different situations.

You can save valuable time by using Makeappicon.com to generate app icons of all dimensions you need for submitting your apps to Apple in one click, no matter it’s built for iOS 7, iOS 8, iOS 9, iOS 10, WatchOS, OS X and iMessage Sticker, and focus on coding and improving your apps.

Here is the dimensions for OS X apps:

After creating all the icons, you should put it into a folder whose name is icon.iconset. The folder must have the .iconset extension. It might look a bit unusual for a folder to have an extension, but this extension is a signal to the system that the folder contains a set of icons.
