To be honest, upgrading to Yosemite was a horrible decision. Liked it for the cleaner look but I don't remember by 13" MBA (2013) being incrediblly slow at everything during Mavericks. - Booting up is slow (usually have a black bar on the top) - Restarting lags - Window sizes are completely random - Apps (Safari//iBooks, etc) lag a bit - Ever since Apple Music, iTunes has been slow - Hand Off / Continuity hasn't really worked or stops working after a while Been using Windows 10 on another laptop with not as good specs as my MBA and I'm pretty suprised by the smooth experience it offers. All I want in El Capitan is a more pleasing experience. Would take 3-5 seconds faster everything compared to a ton of new UI and features that just seems to slow the Mac. Don't want to try out the public beta as I use my MBA for everything. Just a general consesus. El Capitan better than Yosemite?
