The Trouble with Apple is they Brought OSX Snow Leopard and it was a new Operating System its not much younger than Lion and the Same goes for Mountain Lion. Operating Systems are Complicated and instead of Taking Time to perfect Snow Leopard they made Lion and Lion is 1 Year Younger than Snow Leopard and Mountain Lion is 1 Year Younger than Lion So Basically Speaking they are spending too much time making new operating Systems than don't work as well instead of trying to improve the old Operating Systems. I Know Operating Systems are hard to make I have a Friend who made 1 in Binary aka machine Code. And he told me there was so much work involved for 1 person to make it wasn't worth it at all. Now Apple have Many Software Developers and engineers But instead of Taking Time and This also Applies to Modellers in Bryce and other Programs used for Graphics or anything for that matter. The Most important thing is to take your time Don't develope new Operating Systems for the Sake of it and focus on what works. 

A Computer is like an old painting spend time doing it and it will work a treat mess about and try to improve quickly and you'll have a dogs dinner.
