.mpkg File Extension

Developer: Apple
File type: Meta Package File
You're here because you have a file that has a file extension ending in .mpkg. Files with the file extension .mpkg can only be launched by certain applications. It's possible that .mpkg files are data files rather than documents or media, which means they're not meant to be viewed at all.

what is a .mpkg file?

A meta package file is generally classified as a compressed file, and these meta package files are integrated with compression specifications proprietary to Apple, particularly for its Macintosh installer package applet developed for the Mac OS X platform. These meta package files are also implemented with encoding standards, again proprietary to Apple, that are used for the generation of files stored in the MPKG format. Self-extracting functionalities are also built into these meta package files in order for users to just execute the MPKG file and allow the source code stored in the MPKG file to extract certain files and folders and store them in designated directories of the Mac OS X system. The content of these meta package files are generally source code or algorithms developed by Apple for the installation of Macintosh installer packages into Mac OS X. These may include OS updates, small upgrades and fixes or patches. The Mac OS X platform, upon the execution and initialization of these meta package files, references the data stored in the MPKG file and locates the other program files included in the Macintosh installer package, so Mac OS X can store certain files and folders in the appropriate directories and execute other associated files to continue with the installation of the Macintosh installer package.

how to open a .mpkg file?

Launch a .mpkg file, or any other file on your PC, by double-clicking it. If your file associations are set up correctly, the application that's meant to open your .mpkg file will open it. It's possible you may need to download or purchase the correct application. It's also possible that you have the correct application on your PC, but .mpkg files aren't yet associated with it. In this case, when you try to open a .mpkg file, you can tell Windows which application is the correct one for that file. From then on, opening a  .mpkg file will open the correct application.

Apple Installer

Apple Installer

Apple Installer is a system software installer which is already integrated in OS X, or the operating system of Macintosh computers. It has the function to install and extra files of .pkg packages. This installer was first created by NeXT but later maintained and republished by Apple Inc., yet the purpose is still to help developers and creators of software in creating installers for different applications and programs. The versions released by Apple are System 6, System 7.5, Mac OS 7.6, and Mac OS X with distinctive features each. Installer System 6 was a dialogue box so a user could not switch back to the Finder; however, there is a selection of items via the Custom Install. Installer 7.5 was a separate window with windows that are resizable, title bars, info buttons, and hierarchical triangular list view. Installer (Mac OS 7.6) is presently called as the umbrella installer with routine that must be executed. Lastly, the Mac OS X is the centralized program for Mac OS X computers that includes Installer application and to-be-installed software as a package.

a word of warning

Be careful not to rename the extension on .mpkg files, or any other files. This will not change the file type. Only special conversion software can change a file from one file type to another.

what is a file extension?

A file extension is the set of three or four characters at the end of a filename; in this case, .mpkg. File extensions tell you what type of file it is, and tell Windows what programs can open it. Windows often associates a default program to each file extension, so that when you double-click the file, the program launches automatically. When that program is no longer on your PC, you can sometimes get an error when you try to open the associated file.
