Hi, I managed to get an almost new (used 5 Times) MacBook Air 2015 , for £300 so thought id give it a go and sell it on if it isn't to my liking, as a windows user its taking me a while to figure stuff out, and a few swear words to boot. not sure if this should be in the Sierra or air forum, how do these perform? its the i5 1.6 128gb SSD and 4gb ram. Reason I ask is, I installed windows 10 as a bootcamp, more to see if I could rather than use it, it flies in windows 10, quicker than my windows 10 laptop with 16gb ram! however, in Sierra it seems to stutter every now and again. not too much open, app wise, , animations may be a bit stuttery (its a clean install of Sierra) I was just wondering if this is Sierra or the Mac I didn't get a chance to use it on El Captain, so can't compare.
