Hi, I am about to build a fusion drive in a Late 2012 Mac Mini Server. I plan to remove one of the two 1TB HDD's and replace is with an SSD so there. I gather that it's quite straight forward and all I need to do is boot into internet recovery and disk utility will give me the option to 'Fix' the drives which will create the fusion drive automatically. The question I have is that the internet connection is quite slow at the place where I will be doing the install. Can I just download Mountain Lion from the App Store on the Late 2012 Mac Mini and create a bootable USB using Lion Disk Maker? Will this give me the correct version of Disk Utility that's required to make the Fusion Drive? Many thanks!
