Screen Time, introduced in macOS Catalina, is a powerful utility designed to track your application usage, enforce downtime schedules, and set app limits. While it provides excellent parental controls and productivity analytics for many users, it is deeply integrated into the operating system. If you are the sole administrator of your machine and have no need to monitor your own usage, leaving Screen Time running unnecessarily consumes system resources (specifically the coreduetd background process) and clutters your System Settings.
This guide explains how to completely disable Screen Time on your Mac, preventing macOS from logging your app usage and freeing up background processing power.
Disable Screen Time in macOS System Settings
Deactivating Screen Time is straightforward and will immediately stop all local device tracking and cloud synchronization of your usage data.
- Click the Apple Logo in the top-left corner of the macOS menu bar.
- Select System Settings (or System Preferences on macOS Monterey and earlier) from the drop-down menu.
- In the left-hand sidebar, scroll down and click on Screen Time.
- Scroll to the very bottom of the Screen Time pane.
- Click the toggle switch next to Use Screen Time to turn it off. (On older macOS versions, you will click a button labelled Turn Off in the bottom-left corner).
If you have previously configured a Screen Time passcode (either for yourself or as part of Family Sharing parental controls), macOS will prompt you to enter that specific 4-digit PIN before allowing you to disable the feature. Once authenticated, all app limits, downtime schedules, and content restrictions will be instantly lifted.
Important Considerations Regarding iCloud Sync
If you own multiple Apple devices (such as an iPhone and an iPad) and have the “Share across devices” setting enabled, your Mac’s usage data is constantly being synced via iCloud.
When you disable Screen Time on your Mac using the method above, you are only turning it off for that specific device. Your iPhone will continue to track its own usage. Furthermore, if you later re-enable Screen Time on your Mac, it will immediately pull down the existing usage data and limits from your iCloud account. If you wish to completely purge all historical usage data, you must individually disable Screen Time on every single Apple device linked to your Apple ID.
