I am certain. I like the way iOS 10 works and don't want to learn different ways of doing things, and be unable to turn off (really turn off) WiFi/Bluetooth quickly. (I'm a pilot, these things are important.) I like the way macOS 10.12 works (I prefer 10.8, but whatever). At least Apple provides security and patch updates to 10.12 and I can stay on it for several years until they put out another version I either need to upgrade to (for third party reasons) or want to. Apple does not allow me to stay on iOS 10. I have no option to upgrade to 10.3.4 - they won't put out a 10.3.4 even. No, the only option is 11. If 10 is working for me, why am I forced to move to 11? This is very anti-consumer of Apple.
