My Macbook, which has 512 MB RAM is running really slow when I have alot of applications running or when I am returning from sleep. I noticed that apps like iPhoto and the trial version of Word run really slow. Between this I keep on checking the RAM and it's telling me that there is over 100 inactive+free MB. After I close all of these programs and just open up Safari, I get the beach ball and the website takes a while to load. I've downloaded OnyX and ran the maintenance scripts. But the apps still run slow. Anyone know what the problem is?
