As a suggestion, Apple might consider that some people are not mentally challenged and they might wish to stop removing features in their endless quest to appease the clinically brain dead. Since the removal of features from all Apple products, they have become frustating to use. Common things like commands and shortcuts and functions seem to have been replaced with beautiful bitmaps that are nice to look at until you realize that all the features are gone and wish you had gone with windows or linux instead.
Then there is XCode, possibly the singular worst piece of engineering in the history of construction, and that includes the leaning tower of pisa and beaver dams. Using quantum physics, linear algebra and random number theory, mathematicians have been unable to predict the possibility of anyone being able to replicate the poor engineering of the XCode ide, even if trying to do so deliberately. A mentally challenged prawn with a crayon could not possibly make such a mess, or cause as much mental damage as the XCode ide and associated compilers do.
Please Apple, stop making computers and get back to the art school where you belong. Art is an industry that is Ok for mentally challenged users since the product requires no interaction so it is perfect for Apple.
To be fair I think Apple has succeeded where chimpanzees have failed, and that is saying something. Speaking from a local zoo, a Mr. Chimpand Zee said that he was blown away by the frenetic pace of the competition offered by Apple and eventually had to concede that he could not make technology as crappy as Apples no matter how hard he tried.
