I'd add that they had a questionable choice of the Mac and MacBook models they released macOS Sierra for. They left out hardware perfectly capable of running it as if they're trying to force upgrades on people who don't use their computer for computational intensive tasks. I know that these computers are still going to work with El Capitan, but what happens when its security updates will stop? Also, some applications already require Sierra and that's not going to get better.
