So after a lot of requests from our users here is a guide about How to Open .pkg Files to View What Will Install on Mac with Suspicious Package.

Many Mac applications and downloads arrive as a PKG package file, but have you ever wanted to open a PKG file to see exactly what’s being installed and where it’s going from the .pkg source? Assuming you get a .pkg installer from a trusted source like Apple, you generally don’t need to worry about running a package installer file, but not all PKG installers are equally reliable. Plus, sometimes people are just curious about what exactly goes on behind the scenes, what is run by the package installer, and where it wants to put files on a Mac.

This is where the funny named ‘Suspicious Package’ application comes in to play, it’s a free Mac app that allows you to open and inspect PKG installation files before the installation actually runs so you can see what’s going to happen if the PKG is carried out.

Using Suspicious Package to open and inspect .pkg files on a Mac isn’t particularly complicated, although of course it’s best suited for advanced users who have a general idea of ​​what to look at and what to think about it. If you find any of this interesting, you will want to download and install the application, which contains a Quick Look plugin:

Within Suspicious Package you will see three primary tabs with all kinds of information about the package file.

While this is all informative to all users, it is really intended for advanced users who come across package files from dubious sources or who are otherwise questionable. If you download all of your apps, updates, and packages from Apple.com or an equally reliable location, you may find Suspicious Package interesting, but not particularly noteworthy, as the source is trusted, although even packages from Apple can go crazy. like having a package stuck on Verification which can sometimes be fixed with a utility like this. Where Suspicious Package becomes really useful is in more advanced situations where higher Mac security is needed and where users want to be sure that a file is trusted and an installer doesn’t do anything vague when it runs.

Longtime Mac users may remember a package inspection feature existed in Mac OS X some time ago through the right-click menu, but that feature has since been removed. More advanced Mac users can still extract pkg files with pkgutil without actually installing them, but it requires using the command line and the Show Files method to see which files will be installed and where to is not always available or detailed enough.
