safari homepage locked AND UNEDITABLE
A search engine called weknow and the infamous Mac Cleanup snuck in with a flash upgrade. I ran Malwarebytes and it got rid of a bunch of stuff, but after restarts, the weknow site is still my homepage, and it's lightened and un-editable. I literally have NO extensions and I cleaned out any cookies that I didn't recognize. Also searched system files for anything like weknow. No luck.
Any thoughts? Thanks very much.
