"Ok, let me add my experience to this annoying issue.



Yersterday I went to the Palo Alto Store and got my Macbook Pro Retina checked at the genius bar. The guy ran the standard tests like hard drive, memory and so on.



As soon as he checked my serial number and that basically I explained to him that my retina MBP was so slow at some times he inmediatly said: "We know about this problem, we have it already documented, and your serial number is on that batch". Then he said: "We still have no solution to provide, but we will keep you posted, or we will update soon any info about it online".



My concern is my warranty, and should be yours too. And you guys should just basically do the same: go to the Apple store, complain about this, and get your serial number checked.



I'm a long time Mac user and you know the rule: NEVER BUY A FIRST GENERATION PRODUCT FROM APPLE. Truth is, I ALWAYS buy first generation and I've never had such a terrible experience like this before. This is my 30th mac (or maybe even more, I'm not couting) and it's been a mess. Buying a "high end" computer with retina monitor to get horrible performance with "10fps" epic moments is not cool. This is the first time I feel like "I prefer to work on my old 2011 MacBook Air than this thing" and I'm really upset about their answer: "there's currently no solution about this problem" doesn't fix my problem.



Apple, fix this thing already, or just replace the god **** computers already if you are aware of this "small problem". "
