well.... depends. Apple invests heavily into making sure SW runs lean on metal

  Only on newer hardware. Trust me, you don't want to be caught running the latest OS on older Apple hardware because it will run like molasses. If your hardware is the "minimum supported model" or the next most recent, you're better off not upgrading at all.

    MacOS Sierra runs superbly on my 2012 rMBP. It's only a couple months shy of 4 years old.

      Mac OS Sierra slowed down my 2014 Mac Mini noticeably. I see a lot more beach volleyballs now when doing everyday tasks which were ran smoothly before the upgrade.

        I think the difference in experiences is due to HD vs SSD. I've found Apple's latest OS's seem to do terrible with spinning disks. Thankfully all my machines are SSD, but I've seen a few Mac Minis with HDs that are really slow whereas the same machine with an SSD is fine.
