I'm trying to install RetroPie onto my RP, it already worked with the OS it came with before trying this.
I formatted the SD card altogether first and then after expanding the disk image using
dd to put RetroPie (v2.3) onto my SD card, I plug it into my TV's HDMI and nothing happens and when I plug the SD card back into my laptop (Mac 10.9) I get this message "The disk you inserted was not readable by this computer".
Not sure what I'm doing wrong but I've been following this guide:
And haven't gotten passed step one.
Anyone having similar issues?
