Thus far I am very disappointed with macOS Sierra. I have a MacBook Pro late 2011 (2.5 Ghz intel core i5, 4 gb ram) which was running great on El Capitan. Updated today to macOS Sierra and my computer is so slow now, honestly shocked because it's the slowest its ever been. Applications take much longer to open, Siri isn't even worth using due to how slow it is. Everything went so well when I had upgraded to El Capitan, I thought I would have similar results this time around. Anyone else on a 2011 MacBook Pro with better results than me?
