I am installing Ubuntu on my Mac to exist as in parallel with OS X Yosemite, version 1010.3. The screenshot looks similar to previous questions, e.g. How can I resize a partition with Disk Utility?
However, the GUI for Disk Utility does not give me access to resize my partition. Normally, you can click the righthand bottom corner of the volume and drag. I do not have that option---there are no three lines in the bottom righthand for the cursor to drag.
I cannot manually change the size of the partition in the "Size" box. Normally, you could click/highlight the values and change them. I cannot. The text is "faded".
Why doesn't the Disk Utility GUI allow me to choose the size of the partition? Should I just do this via the Command Line?
EDIT: Doesn't anyone else think it's weird that Apple (via Yosemite) forces you to download Windows if you want to partition your hard drive correctly? Note to Apple: FIX THIS!!!
