[QUOTE="jn4jenny, post: 177615"] Firstly, you need to back your important data up ASAP. These things could just be signs of a minor mishap like the need to repair disk permissions or something, but it often means your logic board or hard drive is on the way to failure. And when it goes, it'll go fast. My best advise is to download AppleJack and run it right after you back up your stuff. Onyx and Cocktail are also great for doing general housekeeping tasks while your Mac is still ticking, and they can do almost all the things that Applejack can do + a few more things that Applejack CAN'T do. But once you can't get into Mac OS X anymore (and that might be coming based on the symptoms you're describing), then only Applejack can help you. Applejack runs in single user mode outside of Mac OS X, so you can still get into it even after OS X is no longer loadable. Onyx and Cocktail only run if you can boot OS X. Applejack also saved my butt one time by essentially telling me, from the errors that it spat back, that my hard drive was failing. [url]http://applejack.sourceforge.net[/url] [/QUOTE]
