Longtime lurker, first time poster. I was holding out for a mac mini update but decided to go ahead and go for it! I just got a brand new mac mini, i5, 500 gb and wanted to do a fusion drive from the get-go (240gb Intel SSD). Also doing 16gb RAM upgrade as well. Got drive and RAM installed no problem. I attempted to make the fusion drive using this guide: http://www.macworld.com/article/2014011/how-to-make-your-own-fusion-drive.html However, the computer froze during the process. I forced restarted it and when I booted into recovery mode again, the fusion appeared to have worked, as 1 drive was visible in disk utility, but it was red. I used disk utility to fix the problem and it appeared to do so. I then clicked on reinstall OS X and it started the process. I left to do some stuff around the house and when I got back it was booting, but got hung on the start up screen with the gear spinning and a no smoking sign (circle with a slash through it). I couldn't get it to go past this screen. So I forced restarted it into recovery mode again and now the drive looks like the picture below. Still as a single drive as 740gb. Simply states "Internal Drive" in red. When I click on it, disk utility attempts to fix it: http://s143.photobucket.com/user/blueapplepaste/media/file_zps25f61756.jpg.html?sort=3&o=2 But then disk utility gets hung: http://i143.photobucket.com/albums/r133/blueapplepaste/file_zps0611a868.jpg If I try to quit I get this error: http://i143.photobucket.com/albums/r133/blueapplepaste/file_zps2add8e5f.jpg If I try going into the terminal I get this error: "forkpty: no such file or directory Could not create a new process and open a pseudo-tty" At this point I have no idea what to do. Have thought about trying to take it to apple store, but pretty sure with the DIY fusion that won't fly. Not sure what else to try, I'm in way over my head here. Any help is greatly appreciated!!
