Install Office on a Mac, after use, is perhaps a mistake. Frequent bugs, delays, bias start on Microsoft programs. Coincidence or materially inconsistent? I might have had to listen to a friend "Macophile" who advised me to take office suite by "Steve" with Pages, Numbers and Keynote other. But having a lot of work on files from PC, I preferred the Office solution for Mac. That said, apart from the small annoying bugs, Word and Excel are always powerful and functional ... Dilemma !!!
