10.9.1 fixed one thing!

So which processes were using all your RAM? Do you perhaps have a rogue application on all your laptops?

I have an 8GB laptop that runs Mavericks without any issue like this.

 

i know mine does this on my mac mini when i stream my itunes stuff to my apple tv 2 and any time i access the my hd that has my itunes on from any of my other computers the ram gets all used so people saying the ram usage is better to me its the same as it always been since snow leopard i skipped mountain lion
