in my case is all the opposite , mac os x is faster than windows but maybe is because i have a hackintosh , the only thing that is faster in windows is the GPU in everything else at least on my system mac os x blows windows out the water, i used windows for over 20 years but in my personal opinion Microsoft destroyed windows after windows 7 beginning in w8, i know some people will disagree and that is fine everybody has different taste and opinions but i'm more like a classic desktop user , i know people will say technology move on we can't live in the past and all sort of things, but if i want it a tablet i will buy a tablet and what i want is a desktop pc and that mix desktop+tablet is ruining the desktop system, because i have a bunch of unnecessary apps and services that are not need it or require on a desktop os, taking extra space and using system resources, i believe that windows is a lot buggier than OS X they are still changing adding removing feature not to mentioned everything they copied from mac OS X, i won't even try to name all the features because is a long list, but then apple uses the split windows and they said apple copied that from windows , there are third party apps that does that and all apple did was integrate that to the os , so we can have that option for free , but let's say that apple did copied that from Microsoft, ok is only 1 option vs more than 20 that windows copied from mac OS X , so who copied who, the only reason windows look a bit modern is because they copied dark menu = dark theme among many more other things, windows 10 was close to a year in beta testing, really alpha then after Microsoft released the incomplete buggy windows they still are making changes why because they re still on beta, and that was also another thing they copied from apple because apple have the beta program for us to try and report back and then Microsoft in windows 10 created the insider program so the users can report back to Microsoft so they can fix bug and try to fix the system, they even dared to copied the way apple present their product when Microsoft launched the surface pro, why do i have a hackintosh because i like apple software more but i didn't wanted to pay 4,000 for the trash can because with 4,000 i can build a better system , my system with the sound system, projector , pc tower and all the accessories is close to 10,000 us dollars , it cost me 5,000 to build just the tower alone, and i'm very happy with it even with the limited amount of games because at least i got rid of windows nightmare ,malware, adware, spyware and everything that finished in ware, now in WWDC 2016 apple will show the new os, macos 12 or what ever it'll be called, it only takes apple 4 months to launch the new os, around October but microsoft can't have an os done in 2 years
