Policy Domains
Core set of policy domains and the bundle of settings they configure are:
Allow user access to Accessibility, Date & Time, Energy Saver, Network, Print & Scan, and Time Machine
Allows users to modify settings in the Accessibility, Date and Time, Energy Saver, Network, Print & Scan, Time Machine system preference panes without unlocking or requiring an administrator account. In addition, users can create network configurations ("locations") and can set a DVD player's region code the first time it is used.
Apple limits DVD player region resets to a small number - around 5 - so changing the DVD region code is not enabled by this. Instead, this allows people to play a DVD for the first time when away from IT support.
App Updates and First Launch Config
Disables in-app updates and sets initial configurations - however, these options may not work depending on the app and if the user is migrated on or is a new user.

|---|---|---|
| Chrome | /Library/Google/Google Chrome Master Preferences | Sets default homepage to umich.edu, disable sync initial promotion |
MiWorkspace Login Window Banner

Personal & Private Directory Creation
When a user logs in, create the folder "Personal and Private" in their home directory, and make it mode 700. Additionally, tell the Finder to label it red.

Require a user to enter a password to unlock the screensaver (or when returning from sleep).

Terminal Secure Keyboard Entry
Enables the "Secure Keyboard Entry" by default in Terminal. Secure Entry prevents other apps from listening in on keydown events, which means that other apps can't read passwords into the Terminal window. Note that this will break apps like TextExpander. Also note that recent versions of macOS automatically enable Secure Entry at common password prompts, which is indicated by a 'key' icon in the cursor.
