I've had Mavericks installed for over a few months now, and the computer has slowly been degrading since then. Before I installed Mavericks, my computer ran fine; now it is always using up all 4 GB of RAM that I have, and using up hard drive memory to keep it running, which makes the computer slow to the point where I can't even use it sometimes.
When I look at Activity monitor, my active tasks don't even add up to 2 GB, let alone 4. What on EARTH is the problem and how can I fix it? At this point I just want to do a factory reset on the darn thing.
