Hello everyone! Got a new Macbook (white, 2 GHz) something like three weeks ago. Previously, I've been only using PCs so this is my first Mac ever. During the first two weeks, I have been well impressed with this computer. I was impressed at how well it ran even though it only had the stock 512 MB RAM. But recently, I have started getting the feeling that the machine has gone incredibly slow! What I mean is, for example, I start up Safari, and it takes almost forever (well, at least more than a minute!) just to load my personalized Google start page. But not only that, its also gotten extremely slow at tab switching. I've got the activity monitor running in the background (because it can display this nice animated CPU load diagram in the dock) and every once in a while I fire up its window to see what's happening. And what do I see? Safari is being marked as not responding while loading a webpage. Most often, it stays like this for a few minutes, then it suddenly comes back to life like nothing happened. Also, other apps tend to take immensely long just to show a dialog or something. I thought it was due to my low RAM, but the activity monitor always shows well above 100 MB as being inactive, which I learned from the forums, essentialley means the same as free. I'm starting to suspect the recent upgrade to OSX 10.4.7 to be responsible for this. Since I installed that, I also have the feeling that the activity monitor shows a much higher memory usage for all running processes. Before the upgrade, there were tons of processes which used even under 1 MB of RAM, now, there's not a single one of them left, every process is reported as using at least one Meg and a half. This is extremely frustrating (the slowdown, of course), as the machine right now makes me feel like I'm back working on a 386 running Windows 95. Has anyone else experienced such a slowdown since 10.4.7 or maybe even without installing it? What can I do to make my MacBook fast again? Do I have to upgrade to a Gig of RAM just to be able to work again smoothly? EDIT: forgot to add - when e.g. Safari is being slow, everything else will also stop from responding, even for example the speaker or brightness controls - when I use them, the OSD only appears 10-20 seconds late! I should also note that during the whole time, CPU usage stays pretty low so it's not like there's any serious calculations going on.
