I have a MacBook Air with 64 GB SSD, 8 GB RAM, OS 10.8.3.


After I was running out of space, I used the amazing program GrandPerspective and found out a few things:


- My sleepimage was 8 GB, taking a lot of space, but because it's exactly as my RAM, I can't do anything about it.

- I discovered that my five Apple Mail IMAP email accounts are taking a big chunk of my disk! I sorted my emails by size and erased hundreds of them with attachments from 1 MB to 80 MB.

- I got rid of huge apps I wasn't using, like Google Chrome (1 GB) and others

- I run ONYX, executed all the processes, erased all the caches, etc.


When I restarted my computer I went from 2 GB free to 10 GB free. Huge improvement! But after a few minutes I've noticed that my free space decreased to 9 GB, then 8 GB, then 7 GB in less than 10 minutes. Now, a day after I performed Onyx and erased a bunch of things I discovered that my actual free space is 4 GB... but half an hour later 8 GB...!


WHAT's GOING ONNNN?????? Will I have only 2 free GB in the next hour?

MacBook Air, OS X Mountain Lion (10.8.2)

I think it's also the sleepimage...

    OSX creates temporary files while it is running, what you are seeing is normal.


    You have far too little space available on your hard drive. As a rule of thumb 10% (roughly) should be free while the Mac is running, even though you have a tiny hard drive you are far below that.


    Erasing caches is a waste of your time, the Mac has to waste its time refilling them (as you are seeing)


    Remove files from your drive until at least 10% (or more) is free.
