Hello
@kennedyalk,
Let's check if there any malicious profiles installed on your Mac:
- Go to System Preferences.
- Click Profiles.
- Select any profile and click the remove “–” button in the lower-left corner.
If there isn’t a Profiles icon, you don’t have any profiles installed, which is normal.
Next, let's change your Safari homepage:
- In Safari, choose Preferences from the Safari menu.
- In the window that opens, click the General icon (if necessary)
- Enter your desired home page in the "Homepage" field, but DO NOT press return!
- At the top of the window, click any of the other icons (eg, Tabs, AutoFill, etc).
- You may see a prompt asking for confirmation for changing the home page. If so, confirm.
- Switch back to the General page and check to make sure the home page has been changed.
Let me know if these steps worked.
