Set up Screen Time for yourself on Mac
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.
On your Mac, choose Apple menu > System Settings, then click Screen Time in the sidebar. (You may need to scroll down.)
If you’re a member of a Family Sharing group, click the Family Member pop-up menu on the right, then choose yourself.
Turn on Screen Time, then turn on any of the following options:
Share across devices: Turn on this option if you want Screen Time reports to include time spent on other devices signed in with the same Apple ID.
This option is available only when you’re signed in with your Apple ID.
Use Screen Time Passcode: Turn on this option to secure Screen Time settings, and to require a passcode to allow additional time when limits expire.
You can also do any of the following in Screen Time settings:
Click Downtime, then set up a downtime schedule.
Click App Limits, then set time limits for apps and websites.
Click Communication Limits, then set communication limits.
Click Always Allowed, then choose apps that can be used at any time.
Click Content & Privacy, then set up content & privacy restrictions.
