Long time MacRumors reader, first time poster... Problem: While browsing the internet on my macbook tonight, an OS dialogue window popped up stating that my startup disk was almost full and I needed to delete files. A glance at a finder window showed that instead of the 5.5 GB free I had earlier in the day, I now had about 200 MB free, and that amount was rapidly dropping. I emptied the trash and restarted, after which my hard drive showed about 415 MB free. The only thing I downloaded and installed in this time was Silverlight for mac, so I could watch video on the NBC olympics website. My systems specs are: 2.0 GHz Macbook Core Duo (Purchased summer 2006) 2GB RAM 60 GB hard drive Mac OS 10.4.11 Google searches and searches on the Apple support discussion boards didn't yield anything useful, and the only macrumors troubleshooting thread that seemed even remotely relevant scared me: http://forums.macrumors.com/showthread.php?t=333494&highlight=macbook+hard+drive+filled Any help or advice anyone can offer would be greatly appreciated. Thanks!
