How to remove "Searchmine" as homepage and default search engine on Safari.
I have three browsers on my Mac ( OS 10.13.6) - Chrome, Safari and Firefox. Through my own stupidity I downloaded Searchmine, and it infected Safari and Chrome but not Firefox. I was able to remove it from Chrome but can't get rid of it on Safari. I tried the suggestions I saw when I searched on Apple support, but none of them worked. I would appreciate any help or suggestions.
My iMac is late 2011 -- '2012 and later" was the only choice from the dropdown list.
