Screen Time shows how you spend time on your iMac, provides tools to make it easy to step away during downtime, and lets you monitor what your kids are doing on their Apple devices.
See how you use your iMac. View reports to see how much time you’re spending with apps and websites during a single day or across a week, find out which apps notify you the most, and see how often you pick up your device each day. Open System Settings, choose Screen Time in the sidebar, then click App & Website Activity, Notifications, or Pickups. You may need to turn on Screen Time before these options appear.
