I'm having a bit of an issue trying to install version 4.0 on a 32GB Sandisk Extreme USB 3.0 drive. I've used this drive in the past without issue, but now when I try to install Unibeast 4.0 I get the error "No Disk Available To Install On", with the text "Unibeast installation requires a HFS-partitioned removable disk with at least 7GB free" below.
Nothing changed from last time when I used the old version of Unibeast. I'm running this on the same retina MBP that I always do, with an App Store download of Mavericks 10.9.4. I used Disk Utility to create 1 partition named USB using the Mac OS Extended (Journaled) format, and chose Master Boot Record. When I run the new Unibeast 4.0 program, I get this message.
For reference, when I use a 16GB USB 2.0 flash drive there aren't any issues.
