Long before I started owning a MacBook I was smitten
by these Legendary stories...that I used to hear about Mac that a Mac never...never...ever gets hanged ! 
Was it just a Myth ??
I don't know ?
I am forced to think other wise...
the reason being my experience today and some days back. Today I had multiple activities going on my Macbook, was watching Youtube Videos, some other Videos as well on a Flash Enabled website, couple of more websites open, 2-3 word Documents open aswell and I was trying to copy paste from one word doc to another and when I did tried pasting, the spinning Disc kind of thing appears...just like the sand clock that appears for something is processing in window so that spinning disc appeared and just kept on spinning for about 5 minutes meaning the word.doc did not finish its task and the paste command was not executed, finally I hd to force quit the word APP and reopen it. Only then it got working...And the state of awestruck which I was in, finally got shattered to make me believe that yes ! Even a Mac does hang !! Also I had to restart Firefox also once, even that had stopped responding so I had to force quit that aswell...
By the way on a more serious note do you guys think it was because of no RAM to execute the Task, I have a rMBP 13" with a i5 processor and 8 GB RAM. iStat Menus RAM reading Said I had key 50 MB of RAM left when my word document got hanged. So do you guys think was this because of shortage of available RAM to execute that task, or was it one isolated incident which has a lot to do with the WORD APP and not the entire RAM in general...
