Ok so I've been trying to search around for this but don't know exactly what to do with any of the answers I've found... not a smart one at this type of thing So I get the "your mac os x startup disk has no more space for application memory" message. I am not too sure how to alleviate this issue. It brings up the window to close some things but the only thing in it are Firefox and finder. My HD has 370gb used and 630gb free. My cpu says 6% user, 4% system and 90% idle. My memory says 472mb wired, 637mb active, 105mb inactive and 6.85gb free. With the most simplest of explanations, what the heck do i do? I assume a restart will temporarily fix this issue but what do i have to do to fix it? The issue is on my iMac.. thanks for any help!
