The box on the right shows the free memory 5 minutes after the first without actually doing anything.
I have had a problem with my iMac ever since I installed Mavericks and it is something that seems to be getting worse so I am turning to you clever people in the hope that one of you will be able to explain what is going on.
I am using a mid-2011 iMac and it has 12GB of RAM installed. This should be more than powerful enough to cope with daily demands, but the RAM is running out every hour or so at which point everything slows to a crawl. I read somewhere that an operating system should use all of the RAM available to it to ensure the best possible performance which is fine, but when the RAM runs out I cannot get things moving again until I free some with an app.
At this moment I am running Sparrow, Firefox, TweetBot, Seashore, Bean, Reeder, NoteFile and a few others, but the RAM is still being eaten up at an alarming rate even when I am not doing anything specific. I have tried different browsers, email clients and other alternative apps to no avail. So, do any of you understand what is going on and if so, what can I do to fix it?
