Hi, I'm Bhavik. Welcome to JustAnswer. I'm reviewing your question now, and will reply back ASAP.
Let me know how this goes fro you .
Did you try going to applications (lower left corner of screen) then drag safari back to your dock on your screen? Then you can use safari again. If you do not want to use Chrome and want to get rid of it, go to bottom of your screen in your dock and right click on chrome and click on quit, then go to applications on the dock (far left hand corner) and click on it, find Chrome, then click and drag to your trash can on your dock.
Let me know if this works.
Good Morning, is everything okay? Can I help you any further?
