Is there an application that allows me to play Blu-ray movies on my Mac?
I want to play it natively in OS X i.e. no virtualization.

My macbook air is only about two months old and has a very annoying problem. Almost every time I go to change the site I’m on it freezes. Say I am at youtube and click in my tabs ‘yahoo’. The spinning beach ball like thing pops up and I have to force quit. Why does my mac keep doing this and what can I do to stop it?

It’s a MacBook pro from 2007, I know I’d probably need an older version of Photoshop. I never got any upgrades on my Mac, it’s the same as when I got it.

I just want to make sure what parts of the macbook pro are upgradeable, I will be buying my first mac computer this week and im not exactly sure what specs I should upgrade now before its too late.

Firstly is there a macbook pro that has a 1080p resolution screen
and secondly, what is the GPU in the mac comparable with as far as normal graphics cards go?
