AppReady is a quick and easy solution to creating package files. If you want to sell your software product at Apple's Mac App Store, you must first code-sign it and then convert it into a package file so that you can upload it to iTunes Connect. There are some requirements. For example, the app icon must be a size of 512 x 512 px. The plist file must also have certain keys. AppReady is designed to help software developers complete these requirements and then convert the application into a package file.
