how can i remove bing from my mac

You don't say what you tried except "... i tried all the ways ... " So I'm a little concerned about suggesting a way such as: Bing is a search engine that is an addon to your browser. You must go into your browser setings/config and disable Bing. You do not remove Bing from your computer you remove it from your browser.

I searched frustrated for hours and this ACTUALLY does work!! It won't let me post a link here for some reason but there is a site called thesafemac(dot)com and the programmer there offers an adware program called the AdMedic. It's free to download, though a pop up box will ask you for a donation after install. You can click 'already donated' and it will go away or do what I did and donate a tiny amount once I saw the magic it worked (donation box never came back after that and the donation was through Paypal a few days back and no sign of weirdness there). Anyways, just open the AdMedic program once installed from Applications and run a scan. It finds that crappy crap in a flash and you can delete all at once. It restarts your computer and WHAM, you're back to normal. This REALLY fixed the annoying Bing problem on both my search engine and my tabs. It does reset it to the original Firefox browser which I then set to Google, but all my bookmarks were still in place. Well worth the tiny donation I gave him!! Hope this helps!!

I'm pretty sure that sureshmanuel doesn't need it after more than nine months, but your recommendation is spot on. Too bad it wasn't available back then.
