return it to Apple store, tell them you don't know how to use it

Really , Mac is for rich stupid people, no offense.

When developers develop software for all kinds of applications:car, microwave,cellphone,vending machine, game, they use mostly UNIX/LINUX, others use windows. If Mac is so good, why no developers use Mac to develop software? The only time you use Mac to develop software is to develop Mac software. But you use WIndows or LINUX/unix to develop software for everything else: software that runs on you microwave, car,cellphone. Developers know what's the best platform to use. If developers doesn't know what's the best platform, who else knows?
