I am planning to upgrade on a Unibody Macbook (2008) to Mavericks. Mountain Lion is already installed and I felt it to be a bit sluggish when I upgraded. I also would like to start anew and clear some files that have been on the machine for a few years. So I am wondering:
Would you advise formatting on Mountain Lion, adding files and apps back then upgrade to Mavericks?
Would you advise formatting on Mountain Lion upgrading to Mavericks and adding files and apps back to the Macbook?
Would you advise upgrading to Mavericks then formatting and then format then add files back?
