The ratings for recent two version of os x, namely Yosemite and El Capitan, are so low, especially for current minor update of El Capitan where 1-star ratings are more than 5-stars ones, that I have left my mac on Mavericks, which got a 4-star rating as I remember. Now with Sierra GM out and assuming there would be no major modification for it until future 10.12.x updates, I am wholeheartedly wanting to know how you guys who have GM installed feel about Sierra as rating is a major factor for me to decide whether to update my macbook pro for daily use, let me know your opinion by taking the poll. Thanks a lot Update: current average rating is 4.13 with 109 casts. Since Macrumors is not as a wild environment as Mac App Store, I am guessing Sierra would score no more than 3.5-star in its host country, US, based on current rating 9/20 update: hey guys, Sierra has officially been public. Let's see how it fares.
