Hey guys, Lately I've been seeing the Mac beach ball too many times. I have a 2011 13" MBP, the base-level model, and I installed Lion back when it was launched. It usually happens when I have a few tabs open in Chrome, iCal is full-screen on the next space, uTorrent is downloading something, VLC is paused halfway through some tv show, iTunes is on, etc. There's a sort of multitasking threshold somewhere. Though this laptop is very fast, it's very annoying when it cannot keep up, so I'm thinking if I should do something. 1. Maybe it's a software thing. I've checked and repaired disk permissions and I barely have any apps launching during startup. I rarely restart or shutdown and usually just close the lid. According to Activity Monitor, I mostly have 400-500mb of "free" RAM. I also have 50+gb of free space in my HDD. 2. Maybe I need to upgrade the RAM. Do you guys notice a serious difference? I don't run Photoshop in a regular basis, but I do open a lot of tabs while I have something else going on. It also looks like a cheap fix. 3. I looked into SSD+optibay upgrades, and I think I can cram OSx and all the apps into a main (SSD) disk, while using the older HDD for multimedia files. How much faster does it get? And by this I also mean, what kind of fast. Because it's one thing to do faster conversions, and another to have apps open instantly, snappy spotlight searches, and so on. What do you guys think?
