That said, I will upgrade to Sierra this weekend, let's find out about this ugly system, if at list will work fine. Windows 10 got a lot of process running in background installing things, working on drivers, only advanced users will keep it working for long time. It is not an opinion, it is just the way it works. Windows 10 got a cool design, run smooth overall and nice performance, but there is a big difference, an exclusive feature: it is made to fail. As long all of this is off topic, I will not run away.

I must say I like Windows 10, unlike most of my friends and the bizarre true seams to be is a system that please Mac users. To find your Mac model, memory, storage space, and macOS version, choose About This Mac from the Apple menu. The guy ask for a Sierra upgrade and the answer is Windows 10. If you wish to contribute, please share some links about. Very different from hardware upgrade that I found detailed information easily. I didn't find a deep complete analysis about Sierra in comparison with older OS, what I found is about new features (that most of us will never use) and feedbacks like 'I am using and it's ok'. But there is some issues worth to mention here: Apple is already killing El Capitan, Xcode needs Sierra etc., Apple is being Apple by forcing us to upgrade the system. It seams, for all I did read, will be ok. I'd read this thread to decide to upgrade from El Capitan or not with my MacBook mid 2012.
