ok, so this happened a week ago, and i just switched to my work pc to get through the week. i left my macbook off this entire time and i just switched it on and it started completely, but i still only have 2gb left. i have an external hard drive, but i did have an external just break on me about a month ago, so what can i do to get rid of things on my current macbook?
You strangled the disk with pumping up files until it cannot breathe. Note that, for a good run, you must have at least 10 % free disk space.
Now, if disk is good, no tragedy. One solution is to start up by pressing Shift key, this starts a minimal and safe system which may free up resources. If this works, you may delete files so you may have more free space. If you may free up space in this may, restart normally and you are done.
If you do not have a proper backup, as often happens, you must copy them first, and you cannot do that in this way. Therefore the solution is to start up in target disk mode by pressing T key after chime. You must have a second mac and a firewire cable to connect the two macs. The one started in target disk mode becomes a simple external disk. Now, you can save data then delete files so as to have at least 10 % free disk space.
You cannot safely use a PC for saving data, even if it may detect your mac in target disk mode. You must have a utility named MacDrive, but note that some mac files may get corrupted in Windows enrionment. So, best a 2nd mac and a firewire cable. And, for the future, an external backup disk easily solves the issues.
this helped me tremendously and while i was able to free up 12gb of hard drive, i wanted to back up again on my external before moving photos or music in case i mess up ... however, now my macbook is crashing every time i try to back up using my time machine. it'll start the whole XXMB out of XXGB, freeze, the screen will get dark & have a multilingual screen telling me i need to restart. any idea why?
I got a black screen telling me I had to reboot in many languages, what was it? - http://www.dslreports.com/faq/4970 Also has detailed description of what happens during a KP.

"Try Disk Utility" (modified from http://support.apple.com/kb/TS1417)
1. Insert the Mac OS X Install disc that came with your computer (Edit: Do not use this disc if it is not the same general version as what you have currently on your computer, e.g. use a Tiger disc for a Tiger drive, not a Panther disc), then restart the computer while holding the C key.
2. When your computer finishes starting up from the disc, choose Disk Utility from the Installer menu. (In Mac OS X 10.4 or later, you must select your language first.)
Important: Do not click Continue in the first screen of the Installer. If you do, you must restart from the disc again to access Disk Utility.
3. Click the First Aid tab.
4. Click the disclosure triangle to the left of the hard drive icon to display the names of your hard disk volumes and partitions.
5. Select your Mac OS X volume.
6. Click Repair. Disk Utility checks and repairs the disk."
If when booted to the installer disk Disk Utility does not even detect the drive then it is quite posssible the drive has totally failed and will need replacing.
If the hd totally crashed & burned, then there's nothing to do but replace it.
But in general, I've had over-storage problems on Macs before; sometimes I couldn't even open two internet tabs at the same time. I'll tell you what my problem was. It might help you and others too.
1. My iPhoto library eventually got way too big (including videos shot with my cam). To keep that under control, once a year I burn my entire iPhoto library onto DVDs, and file them away safely. Then I delete the entire iPhoto library and start over again...until another year rolls around.
2. I had way too may iMovie (or Final Cut) events and projects. This is a massive storage issue (esp. if you're filming in High Def.). Once you create and export a movie, the project footage will remain in iMovie, unless you delete it all. I had over 50gb of old footage on iMovie when I first had a Mac and didn't know better. Once you've created & exported your movies, delete the event and project footage.
As for storage, everything has it's pros and cons. I like DVDs because they never crash. But if you have a zillion gb of stuff, then a good external hd is needed.
I think that if the average Mac user keeps iPhoto and iMovie clean like this, these sorts of problems won't happen. Now that I do this, I'm only using 75 out of my 160gb.
Unless you're using true archival grade DVDs there is always a chance of them going bad. I hope you are making multiple copies of each DVD.
Apple at least seems to be under the impression optical media are a thing of the past and seems to be discontinuing hardware and software supporting the use of optical media.
I wrote ‘it seems’, which implies no jump whatsoever. Besides, if the disk is good, may be always used as an external disk for backup or else.
There are, of course,various ways of testing a disk, from the simple SMARTReporter through Apple Hardware Test to more sophisticated methods. Installing via erase-and-install method may also be a simple test, which does not take more than half an hour.
But the list may be longer.
thank you for all of the information. i haven't had a chance to really sit down and open my system using the operating disc. mostly, i'm worried because i partitioned the disc, so my computer can recognize the part that is not the back up of my system. the part that is full of videos & teaching materials can still be accessed, but the backup/time machine part cannot. i went to hong kong over the weekend (i live in mainland china) & bought another hard drive just to try it again, and trying to back up my computer through time machine is causing my computer to crash every time. i'm getting nervous/paranoid because my previous external fell & was unreadable back in january. i went to visit my sister in london around this time and tried to get it fixed there, but just decided it was no big deal because i could get another external as the previous one was 2 years old. so this current backup external is the only backup i have :/ i deleted some preference files to see if it would help time machine, and it seems like it does not. therefore, after this *last* backup attempt, i am going to just manually move all of my files (teaching materials, music, photos) to this new external hard drive (which the computer is reading) and then attempt the disk repair & boot up with the install disc. and if that doesn't work, just wipe & start again? i'm not sure. are there any links or help pages you can suggest to make sure i get everything from itunes & iphoto backed up correctly when i transfer it to my external?
this is my most recent log, if this helps any:
