I have a new MBP Retina - 2.7 GHZ 16 GB Ram.


Every now and then I am having my keyboard lose some key functionality - mainly caps lock, space bar, delete and right arrow, a few others too.

It I have tried creating a new user etc. but it stays the same. It has happened while writing a word doc and today using aperture. In both cases it occurred while flying.


Any ideas

    I think you should go to the Apple Store and set up and appointment at the Genius Bar to exchange your MacBook Pro with a new unit, since it seems yours is defective.

    I don't want to sound stupid... but do you mean "flying" as in an airplane?

    Happy to hear it's awesome it's really hard to push them test and replace something that it's not visible. But you explain the situation maybe it's one of those things they already know and they agree to replace it.


    There is another option if they are out of stock and you don't want to wait 3-4 weeks without your MBPR. They put the deposit with your credit card and let you use the one you have while they are shipping the other one. The moment they deliver the new one they collect the old one. I forget the name of the method it's staring with "M".


    I hope it helped

    I am suspecting the problems seems to be a connection issue with the cable that connect's the trackpad and the keyboard with the logic board. Given that the Retina MacBook Pro constricts so much hardware into a such small amount of space. Again, I suggest going to the Apple Store to have that issue checked. If the Genius Guys don't want to (or can't) help you out call AppleCare at 1-800-275-2273, present them with your problem.


    I would try to reproduce the issue in the ground in the meantime, and run the Apple Hardware Test (AHT). Follow this article to run the AHT. Run the "Extended" test 2 times to see which errors your computer is reporting. Write the error codes down for the Apple Genius Guys to see.


    Hope this helps... Feel free to report back what the Apple Hardware Test gives you back.


    Best of Luck!

    Well, Looks like Apple will be replacing my laptop. I have been waiting for the replacement since the end of June, so it is a long wait.


    Anyway - what I wanted to tell you is that I have made a dozen flights since first encountering this problem and I have narrowed down the symptoms a little further..... The computer (keyboard) works until the plane reaches a certain altitude and then starts to become eratic and as we climb higher, it fails just as described in my previous post. Then, as we decend the exact reverse occurs... non-functional to eratic to fully functional.


    It has to be pressure/altitude related...


    Anyway, I am not sure whether I will ever learn what the problem was, but I can't wait for my replacement laptop.. It is killing me not being able to get my work done on long flights....


    Anyone else with the same issue???




    Glad that your problem has been taken care of... Now I would be inclined to agree in the pressure/atltitude theory. Actually, I think is the reason why you were having the problem. Going to the MacBook Pro (Retina) specs page, I can see that the operating altitude of the MacBook Pro (Retina) is up to 10,000 ft. I guess you are aware of this but the usual cabin pressure in an airplane when it is at its cruising altitude (around 35,000 ft.) the average cabin pressure is the same as it you were at 8,000 ft. That cabin pressure altitude puts it very near to the operational limits of the Retina MacBook Pro.


    Hope this helps...

    This is very interesting to me because I live in Colorado Springs, Colorado which has an attitude of 6,500 feet.  I have the MacBook Pro Retina.  So far it's been running very well but some of the mountain passes here get over 9,000 feet. 


    Thank you for making me aware of the 10,000 foot ceiling for this device.
