Yes on one of my machines, but it's not without issues... I had to reset the PRAM to get rid of the spinning beachball appearing constantly and wi-fi is unstable, constantly dropping connection. Obviously a few bugs still to be worked out, but the other improvements are nice.
My wifi was unstable before the update - dropping connection regularly. I switched the wifi network to a fixed output rather than an automatic one that can switch between n & g and it appears to be fine (so far)
bugger all these new systems .............i am still trying get my i phone 6 to stay connected to any of my hands free in car, drop s off after couple of minutes on all !
