what is terminal and how do i indirectly use it?
I've had my macbook for a year and a half now and updated to OS X Lion a few months ago. Last week I tried installing Rosetta Stone and this app I had never seen before called Terminal popped up. I am not familiar with code writing and didn't know that I needed to be able to in order to install new software. Is it possible that I accidentally changed something in my settings that may have caused this app to run anytime I tried to install a new program? Now I can't update or install software. PLEASE HELP ASAP!
