YouTube TV freezing in Safari

Beleza46,

Thank you for keeping us posted.

Have you had the chance to clear your Safari history?

If yes, we recommend that you check if the issue persists when signed in on a different user account. 

The article below can help if you do not have any other user account to test with.

Set up users, guests, and groups on Mac

"Add a user

1. On your Mac, choose Apple menu  > System Preferences, then click Users & Groups .
2. If the lock at the bottom left is locked , click it to unlock the preference pane.
3. Click the Add button  below the list of users.
4. Click the New Account pop-up menu, then choose a type of user.

• Administrator: An administrator can add and manage other users, install apps, and change settings. The new user you create when you first set up your Mac is an administrator. Your Mac can have multiple administrators. You can create new ones, and convert standard users to administrators. Don’t set up automatic login for an administrator. If you do, someone could simply restart your Mac and gain access with administrator privileges. To keep your Mac secure, don’t share administrator names and passwords.
• Standard: Standard users are set up by an administrator. Standard users can install apps and change their own settings, but can’t add other users or change other users’ settings.
• Sharing Only: Sharing-only users can access shared files remotely, but can’t log in to or change settings on the computer. To give the user permission to access your shared files or screen, you may need to change settings in the File Sharing, Screen Sharing, or Remote Management pane of Sharing preferences. See Set up file sharing and Share the screen of another Mac.

1. For more information about the options for each type of user, click the Help button in the lower-left corner of the dialog.
2. Enter a full name for the new user. An account name is generated automatically. To use a different account name, enter it now—you can’t change it later.
3. Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.
4. Click Create User."

If you are experiencing the issue when signed in on a different user account, we recommend that you check if the issue persists while on safe mode. 

Below is an article to help guide you through the process.

How to use safe mode on your Mac:

"Apple silicon

1. Shut down your Mac.
2. Turn on your Mac and continue to press and hold the power button until you see the startup options window.
3. Select your startup disk, then press and hold the Shift key while clicking “Continue in Safe Mode.”
4. Log in to your Mac. You might be asked to log in again.

Intel processor

1. Turn on or restart your Mac, then immediately press and hold the Shift key as your Mac starts up.
2. Release the key when you see the login window, then log in to your Mac. 
3. You might be asked to log in again. On either the first or second login window, you should see ”Safe Boot” in the upper-right corner of the window."

Take care!

Hi Beleza46,

Thanks for posting in Apple Support Communities. Since it sounds like this happens with a particular website, it would be best to try the troubleshooting from If Safari on Mac doesn't open a webpage or isn’t working as expected - Apple Support. It's important to try all steps and sections of that article but testing in a private window may be particularly helpful in isolating where this occurs. If the issue does not occur in a private window, that may mean that cache, cookies and other data may need to be cleared for YouTube using the following steps.

1. Choose Safari > Preferences, then click Privacy.

2. Click Manage Website Data.

3. Select the affected website from the list that's displayed.

4. Click Remove.

5. Click Done.

6. Open the website again in a non-private browser window.

If the same continues, please let us know if you are using a VPN and what happens when you try accessing YouTube via Safari when connected to a different Wi-Fi network.

Have a great day!

Hello Beleza46,

Thanks for updating us with that information.

If you're seeing that the video is playing at a lower resolution, trying locating settings on the video you're watching to adjust the quality. In addition, check out the following resource we located to see if this may be helpful in clearing up what is occurring: Troubleshoot video streaming issues - YouTube TV Help

If this is only occurring with YouTube TV, we'd recommend working directly with their support team to check into this here: YouTube TV Help

Should you need further assistance, contact Apple Support directly to look into this in detail with you.

Have a great day!
