Got my new iMac the other day (mid-2011 model), migrated my files from a time machine backup and ass is well. Just a little concerned about some of my processes, when I have all my programs open, but idling my activity monitor shows this http://d.pr/YLVS, should 'mds' be taking up this much virtual memory? And can you see anything else out of the ordinary in there? Applications that are open but idling are... Google Chrome, Twitter, Adium, Finder window, Mail, iTunes and EyeTV. I have dual screens so these always remain open, I also have Droplr, and Day One in the menu bar at the top right. Also, I'm in the UK and looking for an extra 8GB of memory, wheres the cheapest/best? Crucial seems okay. Thanks!
