Blocking Safari with ScreenTime

Hello merryheart777,

This page here can help out with setting time limits for the apps you'd like to limit access to: Set time limits for apps and websites in Screen Time on Mac - Apple Support

1. On your Mac, do one of the following:

•If you’re using Family Sharing: Log in to your Mac user account, then make sure you’re signed in with your Apple ID.

•If you aren’t using Family Sharing: Log in to a family member’s Mac user account.

2. Choose Apple menu  > System Preferences, then click Screen Time .

3. If you’re a member of a Family Sharing group, click the pop-up menu in the sidebar, then choose a family member.

4. Click App Limits in the sidebar.

5. If App Limits is off, click Turn On in the upper-right corner.

If the Turn On button is dimmed, you need to turn on Screen Time.

6. Click the Add button  to create a new app limit.

You can include any combination of apps, categories, or websites in each limit you create.

7. In the “Create a new app limit” window, select the checkbox next to each of the apps, categories, or websites that you want to include in the limit.

Search for an app, category, or website: Type a name in the search field. The list updates as you type.

See the apps in a category: Click the arrow  next to the category.

Limit all apps in a category: Select the checkbox next to the category in the list.

Limit all apps and categories: Select the checkbox next to the category All Apps & Categories in the list.

Limit an individual app: Select the checkbox next to the app in the list.

Limit a website: Click the arrow  next to the category Websites at the bottom of the list. If the website has been visited, it appears in the list below the Website category, and you can select the checkbox next to it. If the website isn’t in the list, click the Add Website button  below the website list, then type the URL for the website.

8. Enter a limit in the Time field:

•Set up the same app limit for every day: Select Every Day, then enter an amount of time.

•Set up a different app limit for each day of the week: Select Custom, click Edit, then enter an amount of time for each day.

9. Click Done.

Those steps may help to double-check and see if the limit may be set up for particular days or every day.

You may also wish to upgrade the Mac to the latest version, macOS Ventura, which ensures the device is using the latest available improvements. Requirements and information on this can be found here: macOS Ventura - Apple

Prior to upgrading it's always helpful to ensure there's a recent backup, to help ensure the data is preserved: How to back up your Mac - Official Apple Support
