How can I deal/inspect a suspicious file on my mac short of installing and creating a full blown virtual machine instance? On windows when I want to open a suspicious file I use the sandboxing app sandboxie Is there something comparable/safe on mac?

  • In my case, a zip file containing several files, one of which is a .app file.

    You can explore the app contents without executing it bay right clicking on it and selecting "Show package contents". Jun 8, 2015 at 2:33

Open up the terminal and try:

zipinfo zipFileOfInterest.zip

If you really want some "verbose" information output, then enter:

zipinfo -v zipFileOfInterest.zip

The "-v" option will output a bit more information :)

Also, try man zipinfo to get the rundown of what options/etc is available.

You can also try:

unzip -l zipFileOfInterest.zip

These will allow you to peak inside the .zip without extracting what is inside.
