What is eating my RAM?

I'm really perplexed as to why my iMac us hovering around 60-300 MB of available memory when I have 8GB of ram installed. I tried to look at the activity monitor but I can't identity where the memory is being used. The total I've accounted is well below 8 GB. I've attached an image of my activity monitor. Anyone have a clue where the memory is being used? Do I have a virus?

RAM status is a bit more complicated to assess since Mavericks. It's not enough just to add up how much RAM is used by processes compared to how much RAM you have. There is now memory compression and the OS tries to use all your RAM to be maximally efficient.


Are you having performance problems?

This screen shot says you have 16 GB of RAM and that the "memory pressure" is minimal. Things look good from the RAM point of view. Why do you think there is a problem?


I think the App memory, File Cache and Wired Memory stuff is how to best account for all the used RAM.

BTW, the Google Chrome thing sure looks to be out of control. As usual.

Because unused RAM is wasted RAM. Your system will do its best to fill RAM, caching as much data as it can in "unused" RAM. This is normal. If you're having a problem, describe the symptoms of the problem... otherwise, you're worrying yourself for nothing.
