On your Mac, turn on Screen Time to learn how you spend time on your Mac and other devices. When Screen Time is turned on, you can view reports that show app usage, the number of notifications you receive, and how often you use your devices.
Set up Screen Time
Click the Apple menu > System Settings > Screen Time
If you are a member of a Family Sharing group, click the Family Member pop-up menu on the right, then choose yourself
Turn on Screen Time
Do one of the following
Share Across Devices: Turn this option on if you'd like Screen Time reports to include time spent on other devices signed in with the same Apple ID (you can only select this option when you're logged in with your Apple ID)
Use Screen Time Passcode: Turn this option on if you want to secure Screen Time settings, and to require a passcode to allow additional time when limits expire
Additional Screen Time settings include setting up Downtime, App Limits, Communication Limits, Always Allowed, and Content & Privacy. All of these toggles can help you manage this feature and how you spend time on your Mac.
