I mean, come on??? I don't know if anyone else out there is experiencing what has been going on on my iMac G5, but protected RAM on this machine is a joke. I play three games on a regular basis: WarCraft III, Star Trek: Elite Force II, The Sims 2 and Halo. And all four of these games will create scenarios every once in a while in which the computer will lock up, forcing me to reset it by holding down the power button and turning the computer back on. Things did not use to be like this. If a game (or any application, for that matter) suffered some sort of crash, it would not bring down the whole system. What is the deal with the change? I think this problem is in OS X. Blizzard's website makes mention of experiencing unrecoverable crashes in OS X and gives steps to avoid it as they are trying to sort out the problem. I believe it is Apple, however, that needs to sort out this problem. It really ticks me off that I have to put up with this. I used to be able to look up my uptime and see multiple days, now I have to restart my computer just about every day.
