I recently reinstalled my os its the most current version. Everything worked fine. But when i migrated all my programs and files from my back up, all of a sudden safari does not work. I looked in the /library folder and no folder named safari exists. I think i may need to reinstall safari but i am unaware how to do that because i just cant download it because apple is awesome like that. I do not have a os disk. All that stuff exists on the harddrive under Recovery HD. If anyone can help that would be great. Im asuming im not the only one to encounter this problem.
