I just noticed my mom's white late 2009 Macbook has become very slow. She complained of it being slow to start up/shut down but now that I've taken a look I can conclude that the entire system has become extremely slow. Clicking on any app's menu items on top often comes with a delay and opening apps has them bounce for ages before they actually open. Is there a definitive go to performance tuning resource I should be aware of? The software is completely up to date. It's running the very latest version of Lion (10.7.3) and I just installed the latest version of Safari that came out only days ago. It's got a 2.26 GHz Intel Core 2 Duo and 2 GB of RAM. Could it simply be its age that's making it run this slow? I'd find that hard to believe, but who knows? Just switching to the Finder using its dock icon takes a good 5 seconds and presents me with the spinning beach ball for about a second... I'd appreciate any tips. Thanks!
