To elaborate, I have a 17" Mid-2009 MacBook Pro. I've recently become addicted to Minecraft and noticed that whenever I play my CPU spikes to the roof. Is there any way to keep the game running smoothly? It IS smooth for the most part but there's a few times per play where it'll just slow down and become laggy for no apparent reason at all. I heard somewhere that having the game files on an external hard drive will give a little more power to the CPU but I don't think that's entirely true. Can anyone shine some light on this? Any tips/suggestions are appreciated!
