I started having freezes or lock-ups when using Safari. This is Yosemite version 10.10 14A389 I am to the point where I think I want to do a clean re-install of the OS. 1. What is the best way to do this? 2. Can I bring all my programs/apps back with Time Machine, or should I reinstall each? 3. Is there a different recommendation to solve this issue?
