What is in wired memory?
Recently I bought a MacBook Pro Core i5 with 4GB Memory (RAM).
After using Xcode and quitting it, all of my memory is committed and I have only 100 MB of free RAM.
So I closed all of my remaining apps, but RAM usage is still high and I don't had much free memory.
What's happening? And what is the meaning of Wired in system memory?
