File extension .PKG
|Apple MAC OS X Installer Format
PKG, which stands for Mac OS X Installer Package, is a family of Mac OS X file format used for software installation on a Macintosh computer. It was introduced by Apple Inc. in the early 2000s as an update to the classic HFS files format. PKG files contain.dmg image archives, meta-data files, directory structures, and optional scripts along with text and graphics to facilitate the installation process. The package can be distributed in a compressed form (.zip or.pkg) or completely compressed as a single-file archive (signified by the.dmg extension)
The.pkg file is part of the Installer Package family which includes several other components. The.mpkg packaging file contains the component package file references along with the License Agreement, target operating system information and application prerequisites. It also contains additional script commands that are used to execute or partially execute during the installation processes. Other components such as.pax and.bom files are also included with this file, which record directory structure and content information. Other packages formats part of the family include the .app and .sea which are self-contained applications bundles. Similar file extensions include .ipa, .wim, .dmg, .msi and .deb.
Using PKG Files
The PKG installers are much more powerful than standard macOS package installers. Additionally, they can contain completely customized pre- or post-installation interfaces, allowing an intuitive user experience while operators complete the tasks they need to do. Generally, they provide users with informational resources that can help them more effectively manage their software programs, as well as quick instructions on how to install any available updates. Software developers often use these PKG files to reduce application bundle size, thus freeing up disk space for other macOS operations.
After installing the required software, the operating system will usually automatically associate an unknown file type (in this case .PKG) with the new application. If this does not happen, we can help the system a bit by selecting the software for it, which it should always use to open files with the .PKG extension.
When choosing the software we can select the system to use this software every time.
Using it for the first time it is good to check whether the .PKG file opened in the application can be read by us and opens in a way that allows us to use it. If everything is in order, select this option the next time you open a file with the .PKG extension. However, if the file has not opened correctly, we have to look for a different software, with which we can open files with the .PKG extension. Select a different software from our list and install it on your computer. After the software is installed, repeat inspection openings of a .PKG file. Sometimes you have to repeat the operation several times.
If none of the programs listed by us to work with the .PKG file has not meet your expectations, you can try searching other websites. But remember to avoid downloading programs "that can open any file". These applications not only have very limited functionality, but may also expose you to expense tens of dollars when purchasing a license.
In the vast majority of cases you will find the program dedicated to support the .PKG file, or any other file format. In addition, there is a chance that it will be a free program, and its functionality (concerning the .PKG file) will be extended to the maximum.
It is also good to check
- if the .PKG file has no errors
- or if it has been copied (or downloaded by the browser) thoroughly
