Enable Screen Time on Mac: Steps & Settings

Screen Time on a Mac tracks app and website usage, sets limits, and schedules downtime. You enable it in System Settings (or System Preferences on older macOS), turn it on for your own account or a child’s, and then configure the limits you want. This guide walks through the exact steps for current macOS versions, explains what each setting does, and covers common problems.

What Screen Time Does on a Mac

Screen Time is Apple’s built-in usage monitor and parental control tool, available on macOS Catalina (10.15) and later. It records how long you spend in each app and on each website, shows how many notifications you receive, and lets you set daily time allowances for app categories or specific apps. You can also schedule “Downtime,� a period when only apps you explicitly allow remain usable.

For a personal Mac, Screen Time gives you a weekly report and optional alerts when you approach a limit. For a child’s Mac (set up through Family Sharing), you can approve app requests, lock the device at bedtime, and enforce content restrictions. The feature is free and built into the OS—no separate download is needed.

How to Turn On Screen Time (macOS Ventura and Later)

On macOS Ventura (13) and newer, the setting lives in System Settings:

1. Open System Settings (Apple menu → System Settings).
2. Click Screen Time in the sidebar.
3. Click the toggle next to Screen Time to turn it on.
4. If you’re setting it up for a child, choose the child’s name from the “For� pop-up menu before enabling it. If you don’t see a child, you need to add them in Family first.
5. Click Options (bottom-right) to set a passcode, choose whether to include website data, and decide if usage data is shared across devices.

After enabling, the main Screen Time pane shows a summary of today’s usage. It may take a few minutes to populate data.

How to Turn On Screen Time (macOS Monterey and Earlier)

On macOS Monterey (12) and earlier, the steps are similar but in System Preferences:

1. Open System Preferences (Apple menu → System Preferences).
2. Click Screen Time.
3. Click Options in the bottom-left corner.
4. Click Turn On in the top-right.
5. Choose whether to include website data and set a passcode if desired.

If you have multiple users on the Mac, you’ll see a pop-up menu at the top of the Screen Time pane to select whose usage you’re viewing.

Key Settings to Configure After Enabling

Once Screen Time is on, you’ll want to adjust these settings to match your needs:

• Downtime: Set a schedule (e.g., 10 PM to 7 AM) when only apps you allow are available. You can also schedule different times for different days.
• App Limits: Choose categories (Social Networking, Games, etc.) or individual apps, then set a daily time limit. For example, limit Safari to 1 hour per day.
• Always Allowed: Pick apps that remain available during Downtime and after limits are reached—like Messages or Phone.
• Content & Privacy: Restrict explicit content, purchases, and changes to system settings. This is primarily for child accounts.
• Communication Limits: On child accounts, restrict who the child can communicate with during Downtime and screen time.

Each setting has an info (ⓘ) button that explains the option in plain language.

What Happens When a Limit Is Reached

When an app limit or Downtime begins, the app’s icon becomes dimmed and a small hourglass icon appears next to it. If you try to open it, a full-screen message says the limit has been reached. You have two choices:

• Ignore Limit: Lets you continue using the app for the rest of the day. If a Screen Time passcode is set, you’ll need to enter it.
• Ask for More Time: Sends a request to the family organizer (if the account is a child). The organizer can approve or deny from their own device.

You can also turn off a limit entirely by going back to Screen Time settings and deleting the limit.

Common Problems and Fixes

Screen Time occasionally misbehaves. Here are the most frequent issues and how to resolve them:

• Screen Time isn’t showing any data: Make sure the Mac is connected to the internet and hasn’t been restarted recently. Data can take up to a few hours to appear. Also check that the “Include Website Dataâ€� option is enabled in Options.
• Limits aren’t applying: Verify you’ve selected the correct user in the “Forâ€� pop-up. On a shared Mac, each user has separate Screen Time settings. Also ensure the Mac’s clock is set correctly—incorrect time can break schedules.
• Forgot the Screen Time passcode: If you’re the family organizer, you can reset it from your own device (Settings → Screen Time → Change Screen Time Passcode). If you’re not, you may need to erase the Mac and restore from a backup that predates the passcode—there’s no backdoor.
• Screen Time toggle is grayed out: This usually means a configuration profile (from a school or employer) is restricting changes. Check System Settings → General → Device Management.
• Limits don’t sync across devices: Ensure you’re signed into the same Apple ID on all devices and that “Share Across Devicesâ€� is enabled in Screen Time Options.

Screen Time vs. Parental Controls (Old vs. New)

Before macOS Catalina, parental controls were managed through a separate “Parental Controls� pane in System Preferences. Screen Time replaced that, but you may still see references to “Parental Controls� in older guides. The functionality is now fully integrated into Screen Time. For a child’s Mac, you must set up Family Sharing first, then assign the Mac to the child. The child’s Screen Time settings are controlled by the family organizer’s Apple ID.

Screen Time also differs from the “App Store� restrictions in that it covers all apps, not just those from the App Store. However, it does not block specific websites by default—you need to add them to the “Content & Privacy� → “Content Restrictions� → “Web Content� section.

Frequently Asked Questions

Does Screen Time slow down my Mac?

No. Screen Time runs as a background process that logs app usage and checks limits. It uses a negligible amount of CPU and memory, and most users notice no performance impact.

Can I turn off Screen Time without a passcode?

If a passcode is set, you’ll need it to disable Screen Time. If you’re the family organizer, you can reset the passcode from your own device. If you’re not, and you don’t know the passcode, the only option is to erase the Mac (via Recovery) and restore from a backup that predates the passcode.

Why does Screen Time show more time than I actually used?

Screen Time counts time when an app is open and active, even if you’re not actively interacting with it. For example, leaving a video playing in Safari counts as Safari usage. It also includes time when the screen is on but idle, unless the Mac goes to sleep.

Can I set different limits for weekdays and weekends?

Yes. When you click “Edit Schedule� for Downtime or App Limits, you can choose “Custom� and then set different times for each day of the week.

Does Screen Time work on an external monitor?

Yes, the feature works regardless of the display. It tracks usage on the Mac itself, not the monitor.

What’s the difference between Screen Time and Focus?

Screen Time is about monitoring and limiting usage. Focus (Do Not Disturb) is about silencing notifications and reducing interruptions. They work independently, but you can schedule Focus modes to turn on automatically during Downtime.
