    I just recently cleaned out everything not needed off my 2011 13 inch mbp. When I go to activity monitor I get 299.57 gb free but when I open finder and I-Stat I have 299.31 gb free. I know its nothing big but wondering which one is correct and why the difference of numbers between it all.

    Thats interesting, but as you say .2 of a Gigabyte is nothing. My best guess is that Activity monitor can see how much of the paging file is being used, and therefore gives a more accurate view of the realtime free space. Whereas Finder discounts the Paging file all together.

    Might be wrong- Just a guess.

    Same for me, there is a difference of around 300mb in the two readings (ActMon vs. iStat & Finder). Since my page in is about 330mb, I would say the theory of page files could be sound.

    If you really want to know, try to max out your RAM to force the system to write page files. Then you should see a changing difference in the readings, if the page files are indeed the cause.
