10 Settings to Change After Installing macOS 27

macOS Golden Gate is expected to ship with more toggles buried in System Settings than any macOS release in recent memory. Most of them stay on their defaults after installation, and most of those defaults are not what you actually want.

Once Siri AI is turned on, it draws on personal context across Mail, Messages, and Photos to answer questions and take action across apps. That alone is worth a second look before you leave everything as-is.

Decide What Siri AI Is Allowed to See

Open System Settings, then Apple Intelligence & Siri, and go through the list of apps Siri AI can search. You do not have to grant access to everything at once.

  • Turn off personal context for specific apps if you would rather keep Siri AI to basic requests macOS 27 What Siri AI Is Allowed to See
  • Visual Intelligence, triggered with Shift-Command-Space, can read whatever is on your screen. Review that permission separately from the main Siri toggle

  • Ask to Browse requires a child to request permission before opening any new website in Safari
  • Time Allowances replace flat daily limits with guidance tailored to a child’s age, based on Apple’s own research
  • Schedules control which apps a child can open at different times of day and across the week
  • Communication Safety protections now extend further across messaging and content types
