`foci` is a weird word.

I'm sure Sierra is fine for most users, but for me it's been a dog. Slow, activity monitor spikes, and broke my beloved Karabiner mappings.

This is the first release of macOS I regret jumping on. Here's to hoping the point releases are significant

Sorry to hear that it is not working out for you. For me it speeds up my old Mac Mini so it feels like it is twice as fast. Specially launching of Apps. One of the best upgrades in many years.

This has been reported for days. What's doing the slowing down and Activity Monitor spikes is Sierra indexing. I noticed with iStats that I use the CPU was running very fast. Give it some time and depending on what year of your mac and how much storage you have used, it could take awhile. Once the indexing is done, do a reboot too. Btw, the cause was mainly Photos. With my iMac and it's a recent 5K, it still took some time to index. Hope it helps.

I haven't had performance problems probably because I leave the computer turned on and plugged in all the time. That allows Mac OS to do a lot of stuff in background such as indexing the drives. Golden Master has been awfully good from my perspective.

Hiwever installinnghte first minor update hasn't been all that wonderful with a few glitches here and there. Nothing major but frustrating nine the less.
