Hi wasitcovid19,
Just to confirm, have you had a chance to verify that JavaScript is enabled in Safari on your Mac. This article will walk you through the steps: Change Security settings in Safari on Mac.
If so, you may find the steps in this article helpful if a webpage isn't working as you expect: If Safari on Mac doesn't open a webpage or isn’t working as expected.
If the issue persists after going through those steps, you can further isolate it by testing it in a new administrator account. This will tell you whether the behavior is limited to a single user account or if it's possibly a system-wide issue. If needed, this article will guide you through creating a new account: Add a user or group on Mac.
1. On your Mac, choose Apple menu > System Settings, then click Users & Groups in the sidebar. (You may need to scroll down.)
2. Click the Add Account button below the list of users on the right (you may be asked to enter your password.)
3. Click the New Account pop-up menu, then choose Administrator.
4. 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.
5. Enter a password for the user, then enter it again to verify. Enter a password hint to help the user remember their password.
6. Click Create User.
Regards.
