What is a .APPDOWNLOAD file?

An .APPDOWNLOAD file is a type of file specifically used by the Mac App Store, which is a feature included in versions of Mac OS X starting from 10.6.6 onwards. This file format is created when a user purchases and downloads an application (.APP file) from the Mac App Store. The .APPDOWNLOAD file represents a partially downloaded state of the application. This means that the download is not yet complete, and the file is essentially a placeholder containing parts of the application's data as it is being downloaded.

To open an .APPDOWNLOAD file, you need to use the Apple App Store application, which is automatically included with the operating system on Mac computers. Normally, users do not need to manually open .APPDOWNLOAD files, as the downloading and installation process is managed by the App Store itself. Once the download is complete, the .APPDOWNLOAD file is automatically converted into a fully functional .APP file, which is the standard format for Mac applications. The App Store then proceeds with the installation of the application on your Mac.
