Mind throwing me the name of or link to the program you used to unpack the .app? I'd like to do that myself, and remember stumbling on a program that did that, but can't recall the name.

Suspicious Package and Pacifist are great tools, but you can do it with the built-in pkgutil command:

    % pkgutil --expand foo-1.0.pkg foo_pkg
    % cd foo_pkg 
    % ls -Al
    total 352

    -rw-r--r--@ 1 magervalp staff  67794 16 Mar 12:19 Payload
    drwxr-xr-x  4 magervalp staff    128  9 Apr 13:51 Scripts
    % mv Payload Payload.cpio.gz
    % open Payload.cpio.gz

Been using 'Suspicious Package' lately: https://www.mothersruin.com/software/SuspiciousPackage/

I'll throw in a plug for the tool I've written, unpkg: https://www.timdoug.com/unpkg/

This is what I used, but it looks unmaintained; I'd try others' suggestions first: https://www.macupdate.com/app/mac/45385/payload-extractor

Got me curious too. Answer Just a google search away.

Pacifist used to be the go-to app for this; probably still is.

7-Zip can do it on windows, maybe there's an osx port?

7-Zip, now there's a fantastic piece of software. It opens damn near everything, has an ultra-lightweight interface and doesn't have any near-malicious money grubbing schemes.

It's not safe to process untrusted files with 7zip

7-zip is great. The Unarchiver is its equivalent on Mac. Suspicious Package is better for this particular file format because it shows what the installer will do, not just what it has in it.

Keka is my go-to for this, actively maintained by its author.
