Macs do have physical turn off buttons, what the hell are you talking about?
Also, OSX does have the equivalent to ctrl+alt+delete, where you can force quit unresponsive programs.
My Mac is very fast.
I couldn't understand anything else you typed.
At school, they had some mac laptops. When they crashed (Lol macs never crash. ) pushing the power button wouldn't do anything. To restart them, we would have to open the case and remove the battery. ~_~
Did you try holding the power button in?
If that doesn't work, then yeah, unplug the battery. I had to do the same thing with my Dell laptop every now and then. Actually, a lot. Because it crashed, a lot.
(P.S. I never said Macs
never crash. I just said mine hasn't, yet. Read, comprehend, post.)
