safari deleted off computer. How to get it back
I restarted my computer and when it turned back on, my safari was no longer on my computer. ive searched in my apps and documents but it isnt there. I really need it back because i cant find my hard drive on my computer either so when i download another browser i cant even save it to the hard drive. Google chrome doesnt support some of the websites i need to get onto so im desperate.
MacBook Pro, OS X Yosemite (10.10.2)
