Hello I am a huge newb at macs and computers/mac. I got my first and only 4gb MBP not even 2 years ago and it has worked great until now. I am a basic browser and only download music and videos (onto a separate external hard drive.) i dont play games or do anything intense. I feel like slowly yet suddenly I get the spinning beach ball ALL THE TIME now. It comes up with everything I do now. ...When opening new safari windows, running new apps , etc. ANYTHING causes the beach ball to come up early and often. I looked and I only have 2/4 gb used up. Is that a lot ? Can anyone please give me advice how to fix this problem or where I can go to get help! Do I need more memory?? All help is greatly appreciated. Thanks!
