Ok had sometime to play with the MBP, Traktor with my S4. WOW works great!! I had the latency set to the lowest possible, had 2 decks playing all sample decks looping and both FX on. Then I just started going crazy with any and everything to see if I can make it crash. All worked well!! But I did manage to crash it while I added a folder to a playlist. Screen went back but the music kept playing. Keep in mind I had other apps open and also running VMware with windows 7. Yes I can’t let go of some windows software so I installed it on my mac. This also works great! So I did a reboot with nothing else running except Traktor and my S4 no problems at all. CPU meter barely moved!
So all in all im loving my mac! If your in need of a new laptop go mac!!! Not to say windows sucks but I see now what the hype is all about…or should I say it’s just reality?
