Files installed by Zoom for mac OS

The Zoom install package for macOS is mad. Rather than actually using the installer to install things, it does everything in the preinstall script. That's bonkers, and also means that the system won't have a list of the files it installed, because it's doing it using shell script.

The script appears to install two items, namely:

/Applications/zoom.us.app
~/Library/Internet Plug-Ins/ZoomUsPlugIn.plugin

If the user opening the package isn't an administrator, it looks like it will install the app in the user's home folder instead. If they are an administrator, Zoom will delete the ZoomUsPlugIn.plugin from /Library if it's there, but it still installs to ~/Library.

It also adds Zoom to your Dock automatically, without asking.

APFS Container cloning/replicating under Catalina (with a bootable system)

Today I wanted to move existing APFS-resident macOS Catalina installation to a new disk. I upgraded my late 2014 Mac Mini with a shiny new 1TB SSD. This took way too many hours of my life I will never get back. Hope this saves some time to you.

Good news:

  1. it is possible to create a DMG image from existing APFS container with macOS Catalina installation including metadata needed for complete restore (the DMG contains OS, OS Data, Preboot, Recovery and VM volumes)
  2. it is possible to restore this DMG image into empty APFS container and get a bootable copy of the original system

This information is relevant for Catalina (I'm currently running macOS 10.15.1).
