Hope you like spinning beach balls...because you're gonna get plenty of them if you upgrade to the latest Mac system — Sierra ..
A bullshit OS ... and Mac is rushing its stuff out just for the sake of rushing it out.
God forbid they make sure it works first.
What a piece of crap.
And I've been a Mac guy since 1987 ... Sierra is the latest in Mac's overpriced crap.
If you like Beta programs, you'll love the finished product that is Sierra.
