pkg2app is a small application written in AppleScript to help install games from GOG whose installers give an error during game installation.
Most Mac games from the GOG app store are distributed as packages, more specifically .pkg files. They are very convenient, you just need to double-click on the file and the installation process will begin, but it happens that it ends unsuccessfully and most often this happens with rather heavy games. This also happens with official .pkg files, and the problem is most often not due to your actions.
You can try to extract the game files from the .pkg installer yourself using the standard pkgutil utility or using special programs designed to extract files from .pkg, but the utility developer has already done everything for you.
The utility is very easy to use. On first launch, a small window will appear with several options on how/where files from .pkg installers will be extracted (this can also be changed in the application settings). After choosing this setting - just drag the .pkg file with the problematic game or dlc onto the pkg2app application icon and the extraction of files from the installer will begin.
What’s new
Changes:
Can now handle all installers at once without having to be concerned about installing order.
Complete graphic user interface, with multiple file selections, preferences, loadings, notifications and a HD icon.
Default extracting behavior can now be changed to “Always ask where to extract”, “Always extract next to the installers” or “Always extract in a specific folder…”. You’ll be asked the first time you run the application, you can double-kick the .app to change it later.
It now only accept installers from GOG to prevent mistakes and misuses
