A bit of background before I start. I'm trying to install Ubuntu onto my Macbook Pro and so far I've stumbled into a bit of a roadblock. I've also already installed Windows 10 with Bootcamp, I'm not sure if that makes a difference.
The issue I'm having is whenever I try to create the partition using Disk Utility it seems to get stuck at "Preparing to partition disk" no matter how long I wait for it. It really doesn't seem to matter what format I make the new partition, I still end up getting the same issue.
If anybody has any idea why this is happening or what I can do to fix it would be greatly appreciated.
