The approach we'll use to convert the pkg files works on both Windows and Mac, making it a great backup plan in case something happens to your Mac. This article will demonstrate how to convert pkg files into app files on any device by using the Recovery Mode.
If you don't have a Mac, it will be more challenging to convert this file on your Windows PC. Simply opening the file will cause the decompressor to create a '.app' file in the Applications folder. On a Mac, extracting a pkg file is rather simple. The InstallAssistant file is packaged as a '.pkg' file.
In more current versions like macOS Big Sur, macOS Monterey, and macOS Ventura, we may use an InstallAssistant file directly from the Apple server.
