High memory usage on MacBook PRO retina 16Gb i7 2,5ghz I'm using a MacBook Pro  Retina 15-inch 16Gb
Processor 2,5 Ghz Intel Core i7
Graphics Intel Iris Pro 1536 Mb
OS: OS X  Yoseminte v10.10.2

I'm having a problem with my ram. I think its eating too much rum when I'm not doing anything..

Please find my screenshots attached.





And this is how it looks when I have the Adobe Photoshop open (a small psd file 5,2Mb), Microsoft Word (1 page), Itunes, And the Chrome Browser (12 tabs opened)







Can someone help me with this issue? Why is it eating that much RAM?
If there is any other info that you need for this situation please tell me so I can get that for you.
Thank you 

MacBook Pro with Retina display, OS X Yosemite (10.10.2)
That's perfectly normal for Yosemite - the new rule is "empty RAM is wasted RAM."

The system will fill the RAM so that any process needing to quickly use it has it already available, rather than having to request more.

As you see from your pictures, the Swap file is zero, so nothing is being traded off to the hard drive. That's about as good as it gets - everything that needs RAM has all it needs &amp; nothing has to use the slow swapfile instead of real RAM.
You also have zero memory compression, so there is no pressure at all on the machine's resources. Everything is as it should be.

Old-style memory flushers are actually less than useful under the new memory handling routines &amp; will slow the machine down rather than speed it up.
