A few months ago, I got a message that I was running low on space and couldn't hold a son I downloaded from iTunes. Opened up my HD and at the bottom, I had only 98kb available. I restarted, nada. After being stumped, called my investment firm, AppleCare. They walked me thru dl'ing an app that will 'visualize' you HD contents, found that a folder had an 84GB log file in it. (Library>Logs>Console>-501). The tech was able to walk me thru ridding the folder, rebooting, and in front of my eyes I watch 84GB come back to life. Cool! Until it happened the next week. I called AppleCare back, proceeded to walk them through what fixed it originally, and they told me to do that again. And then the next week it happened. I got tired of calling AppleCare, and it still happens about every week or so. I rarely ever shut my iMac down, letting it sleep when it wants, back up on a regular basis. I tried shutting it down every night and this didn't do anything. Nothing seems to take care of it, I'm at a loss of words on what to do. I have an iMac, 17", 2 Ghz Intel Core 2 Duo, 1GB RAM, SuperDrive, etc. Any help as to how a console file will go up to max HD size?
