How to get a list of the installed app on my Mac?
system_profiler

To list all the applications on a Mac, use the system_profiler command:

system_profiler SPApplicationsDataType


This will output the command in human readable format:

   Power Manager:

      Version: 4.6.1
      Obtained from: Identified Developer
      Last Modified: 20/01/2018, 6:42 pm
      Kind: Intel
      64-Bit (Intel): Yes
      Signed by: Developer ID Application: Dragon Systems Software Limited, Developer ID Certification Authority, Apple Root CA
      Location: /Applications/Power Manager.app


This will include every application on the Mac, including many that are hidden within folders.

XML Formatted List

Add the -xml option to the command for a format that can be parsed and analysed by other tools:

system_profiler -xml SPApplicationsDataType


This will output a Property List (XML), such as:

        ...
        &lt;dict&gt;
            &lt;key&gt;_name&lt;/key&gt;
            &lt;string&gt;Safari&lt;/string&gt;
            &lt;key&gt;has64BitIntelCode&lt;/key&gt;
            &lt;string&gt;yes&lt;/string&gt;
            &lt;key&gt;info&lt;/key&gt;

            &lt;key&gt;path&lt;/key&gt;
            &lt;string&gt;/Applications/Safari.app&lt;/string&gt;
            &lt;key&gt;runtime_environment&lt;/key&gt;
            &lt;string&gt;arch_x86&lt;/string&gt;

            &lt;/array&gt;
            &lt;key&gt;version&lt;/key&gt;
            &lt;string&gt;11.0.3&lt;/string&gt;
