I have a mid 2009 MacBook running OS X 10.6.8 (Snow Leopard) and over the past year or so it's really slowed down. It has 2 GB of RAM. I try to only have one or two programs running at once because anymore than that and it starts to freeze and I get the spinning beach ball on whichever program happens to be at the front. Skype, iTunes, and Chrome seem to run the slowest. All are up to date. I had a similar issue with FireFox a while back and it got to the point where I couldn't even open the program without it freezing and crashing. That's when I switched to Chrome. Now Chrome seems to be doing the same thing. It almost always crashes when I watch Netflix. Safari is even slower than Chrome. Last night it developed a new quirk. I had it sitting out, plugged in (the battery has its own set of issues), Chrome open, and the screen darkened as it always does when it's been sitting out unused for a few minutes. Then it froze. The mouse wouldn't move, the keyboard wouldn't work, I could not do comand option escape to quit any programs. I had to push the power button until it turned off. It turned back on normally and I immediately did a time machine backup. Same freezing thing happened during the backup. I turned it off and on again and did another backup, just to be safe. It hasn't frozen since. Right now, with only Chrome and Activity Monitor open, it only has 15.8 MB of free RAM. So, questions: 1. Is this a RAM issue? Would buying more RAM fix it? I'm hesitant to put money into an almost 6 year old laptop. 2. Does anyone know of another browser I could try besides Chrome, Firefox, or Safari? 3. Anyone else experienced the freezing thing? Does it happen more frequently as time goes on? 4. Would upgrading to Yosemite help? Or would that be an awful idea? Thanks in advance!
