Can you please check if there's an AdminPrefs file on the device. If it's there, you should remove it.

  1. Go to System Preferences.
  2. Click Profiles.
  3. The list will include an item “AdminPrefs“. Select this and click the remove “” button in the lower left corner.

Next, for Safari 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.

To completely remove this browser hijacker from Chrome, we will need to uninstall the browser and delete all data, then reinstall. To do this, delete all of the following items:


/Library/Application Support/Google/


~/Library/Application Support/Google/


Be aware that this will delete all data for all Google apps you have installed, such as Chrome bookmarks. Export any data you want to keep beforehand.

If you're not sure how to find these folders, choose Go to Folder from the Go menu in the Finder, then paste one of those paths into the window that opens. Be sure to delete the correct item, as deleting the wrong item could cause data loss or even damage to your system or other apps.

After deleting all these files, restart the computer. Then re-download Chrome and reinstall. You will need to import any exported bookmarks or other data, and may need to reinstall any other Google apps that you use.
