   1. Remove unknown profiles if present.

      System Preferences > Profiles

      Open System Preferences,  select “General and click  the “Profiles” icon ( a checkmark on a gear) .

If Safari's home page is stuck

In some cases, after being changed by adware or malware, Safari's home page can become stuck. You will be able to edit the Homepage field in Safari's preferences, but the change will not stick. This appears to be a bug, and there is an odd workaround.

Try this:

1. In Safari, choose Preferences from the Safari menu.

2. In the window that opens, click the General icon (if necessary)

3. Enter your desired home page in the "Homepage" field, but DO NOT press return!

4. At the top of the window, click any of the other icons (eg, Tabs, AutoFill, etc).

5. You may see a prompt asking for confirmation for changing the home page. If so, confirm.

6. Switch back to the General page and check to make sure the home page has been changed.

You have adware/malware installed. Use  Malwarebytes Anti-Malware for Mac https://www.malwarebytes.com/mac-download/ . It may be necessary to run more than one scan. After scanning a couple of times, restart the computer and test. If necessary, follow the manual instructions. Do not download any other programs that are listed in the articles.

Safari Homepage setting greyed out https://discussions.apple.com/thread/8637822

Go to Safari Preferences/Extensions and turn all extensions off. Quit/reopen Safari and test. If okay, turn the extensions on one by one until you figure out what extension is causing the problem.
