Mac Os Sierra on a MAC PRO 5.1 works great!

Mac Os Sierra on my mac pro 5.1 with 40 GB of ram and a samsung solid state disk. Runs as fast as Mavericks (or maybe half of second slower), but much better than El Capitan!! Video is in spanish. If you machine can handle it (check minimum requirements), then upgrade! Note: I didn't activate SIRI.. It takes A LOT OF MEMORY!
