I was running into a bug with Sierra where the Cocoa version of Emacs would sometimes trigger a bug in DisplayServer that made it use 100% CPU. Fortunately, that is solved in High Sierra. Unfortunately, I have some other fun regressions: - Preview has become pretty much unusable. It crashes often when zooming PDFs. It also often doesn't linearly go through pages/slides when pressing the down key when a thumbnail is selected. - The other day my MacBook Pro (2016) showed the charge icon, but it didn't actually charge. I noticed when it was at 5%. Unplugged and plugged the charger and it works again. - Keynote doesn't open (some?) presentations produced with PDF2Keynote anymore. This worked fine in the previous version of Keynote.
