    I have like 100GB of empty space left on my Hard Drive that I want to add to Macintosh HD, but I can't change anything because it is Master Boot Record. There HAS to be some way... this is freaking ridiculous.

    iPartition might do it for you.

    I bought iPartition a couple of months ago and it did NOT do as advertised; it would NOT change MBR to GUID. It was an expensive lesson. Outside of resizeing partitions, it is little more than a graphic toy.

    Do you have an external drive around? You should be able to clone your data to the external then reformat to GUID the clone the data back. Then with GUID you can use Disk Util to monkey around with your partitions.
