Hi everyone, I picked up my first Mac (late 2013 iMac, 2.9ghz, core i5, 1TB HDD) as an impulse buy since it was a floor model for a crazy low price. It came with Yosemite. Do you think it's worth it to upgrade the Mac to Sierra, or will it slow it down too much? I'll be using the iMac for Adobe CC, possibly Ableton/Pro Tools 10 etc., and I'd like to pick up a Magic Trackpad 2, which I believe requires El Capitan. The iMac's bluetooth is kinda wonky as well. Thanks for your advice! So cool to hear the Mac startup chime in my studio (which has previously been PC land)!
