Screen Time on the Mac is Apple’s built-in tool for seeing exactly where your hours go and putting limits on the apps and websites that eat them. It is free, it is already installed on every Mac running macOS Catalina or later, and it syncs with your iPhone and iPad. This guide walks through turning it on, reading the reports, setting app limits and downtime, and using it for a child’s account — no third-party app required.
Where to find Screen Time
Open the Apple menu → System Settings (called System Preferences on macOS Monterey and earlier), then click Screen Time in the sidebar. On the first visit you may need to click Turn On App & Website Activity — nothing is tracked until you do.
Read your usage reports
The App Usage, Notifications, and Pickups panels show a day-by-day breakdown. Switch between Day and Week at the top, and click any bar to see the exact minutes per app or website. If you own an iPhone and iPad signed in to the same Apple Account, turn on Share Across Devices to combine all three into one report.
Set an app limit
Click App Limits → Add Limit, pick a category (like Social or Games) or a specific app, and choose a daily time budget. When you hit the limit the app dims and shows a time-up screen. You can allow a one-off extension, or lock limits behind a passcode so they can’t be waved away — useful on a shared or child’s Mac.
Schedule Downtime
Under Downtime, set a window (say 10 PM to 7 AM) when only the apps you allow can be opened. Add the essentials — Phone, Messages, an alarm — under Always Allowed so they keep working during downtime.
Block adult websites and set communication limits
Content & Privacy Restrictions lets you filter adult web content, block specific sites, and restrict explicit media in Music, Podcasts, and the App Store. Communication Limits control who can be contacted during allowed time and during downtime — the core of a parental-controls setup.
Screen Time for a child’s account
The cleanest way to manage a kid’s Mac is Family Sharing: add the child’s Apple Account to your family, then manage their Screen Time remotely from your own devices. Set the limits before you hand the Mac over, lock them with a Screen Time passcode that is different from the login password, and you can approve or deny extra time right from your phone.
Does an older Mac handle this fine?
Screen Time is a software feature, not a performance one — it runs identically on every supported Mac, so you do not need new hardware for it. A refurbished MacBook Air M1 from $569.99 runs the current macOS and every Screen Time feature described here. If you are buying a first Mac for a student or child, browse the Apple clearance deals for the lowest-priced models that still get full macOS updates.
FAQ
Why is Screen Time showing no data? You likely never tapped Turn On App & Website Activity, or tracking was reset. It starts logging only from the moment it is enabled.
How do I stop the limit pop-ups on my own Mac? Go to Screen Time → App Limits and delete the limit, or toggle Screen Time off entirely at the top of the panel.
Does Screen Time slow down my Mac? No. It is a lightweight system feature with no measurable performance cost.
Can I use Screen Time without an iPhone? Yes — it works fully on a Mac by itself. Sharing across devices is optional.
