I've owned a 2011 Macbook Air for 3 yrs. Yesterday I gave it to my husband and bought a new Macbook Air for me (his 2009 Macbook Pro had a dead HD and I always get the new ones!) Anyway, I used my backup to put all my "stuff" on the new MBA. It worked great and I now have a clone of my old one.....but, I've realized I don't have the additional apps (like Numbers and Keynote etc). How do I get those? I know they must be in here somewhere?
