I noticed when I boot into 10.9 after shutdown and I go into activity monitor 2GB of my 4GB is being used. Is this normal? nothing is open other than activity monitor. I have zero performance issues, I just wanted to know if that was normal. How much memory does your system use at boot?
Got a tip for us?

Yes, it is normal. With Mavericks' new memory management system, the OS may use all the available ram even when nothing is open. This does not cause any problem, and actually improves the overall performance of the system.
What you should look at Activity Monitor is the memory pressure. If it is at high levels, it can cause performance issues.

As I understand it Mavericks pre-loads commonly used programmes in anticipation of you using them. If you don't and it needs the ram for something else it over-writes it. All this is very quick and improves system performance.
