I have to say connecting a Macbook Pro to a tv via HDMI adapter is a huge pain in the butt. This is a new model bought for my daughter about 3 months ago and the adapter is apple original.
Every single time I connect it to her tv (a Samsung 1080P 46", relatively new) I have to spend time reconfiguring the resolution. Sometimes it does not work at all and requires a log off log on. It is not the adapter as I bought her another one just to be sure.
Even better is that the audio does not work plug and play. Again, every single time I connect it (and this is the only tv is has ever been connected to), I have to go in to the audio settings and make a checklist of changes, log off, and then log back in for it to work. If you disconnect the laptop or heaven forbid shut it, you have to go through the process again.
I even thought there was an issue with the laptop itself but I also bought my wife another Macbook Pro and it has the exact same issues.
The only way I figured out how to fix the audio was to go into the mac forums (where apparently this is a common issue).
I have hooked up over a dozen windows based laptops to tv's and have two media centre pc's in my house running windows. Every single one of them has been plug and play every single time.
For that alone, I would steer clear of a Mac.
Add in the formatting incompatibilities between external drives with windows and mac and the exorbitant price (my daughter's laptop cost $400 more than my Asus Ultrabook and frankly my laptop eats hers for breakfast in every category and matches in battery life + 2 year warranty first year covers drops!), I would not recommend a Mac voluntarily to anyone.
Set aside the counter intuitive nature of the OS (that is supposed to be oh so user friendly), it is simply an experience I have no interest in using for myself.
