You can find Armin’s and other presentation videos here:

-Armin’s career goes from Germany, to the United States and currently in The Netherlands.  During his career he had the opportunity to work for Apple.

-Before moving back to Europe, Armin was training his replacement when he was asked about books available to learn topics for the Mac.  This was one of the inspirations for writing his first book.

-Before “Moving to zsh, Armin wrote three other books:
Packaging for Apple Administrators:
-PropertyLists, Preferences and Profiles for Apple Administrators:
-macOS Installation:

-Upgrading a Mac to Catalina, 10.15 will result in your default shell remaining at bash

-If you create a new user, clean install the OS, or purchase a new computer, your default shell will be Z Shell

-Questions come up related to current commands and scripts and how they are affected by the change

-Sam lets it slip that he is now running Catalina on his production computer

-He discusses an issue with Reminders in Catalina and Joe talks of the Apple Mail data loss issues

-Sam asks Armin if we will see Erase All Contents and Settings in Catalina since we now have separate APFS containers for the OS & data, similar to iOS

-User enrollment is another new feature that is fascinating for features like enterprise wipe

-Erase & Install is a custom app that Armin wrote (, which gives the user a user interface that leverages startosinstall to wipe a computer.  In Europe, with GDPR, this provided a confirmation for a user that a business computer was wiped of personal data.
