Hey guys. So I wanted to play around with Yosemite... so I created a second partition, installed Yosemite on it... and it has been working great. However... I ran into a slight problem when I noticed I was running low on space on the Yosemite partition. So I went into disk utility, and confirmed that i was just about maxed out on space on my yosemite partition. I noticed that I wasn't able to resize my original partition, or my Yosemite partition... http://i.imgur.com/rwBA3Bf.png (Pic of Disk Utility). When I select the top level 'Yosemite' HDD, and go into Partition... I notice when I select the initial partition, the '-' remove button enables. When I click it, it asks if I want to remove the partition, I click yes, and it lights up and claims it's finished... but the partition remains untouched. Any ideas? I'm basically wanting to remove that first partition completely, and have the yosemite partition consume the entire drive.
