Hi, I have a 2104 iMac that I want to install elementary on. I can boot from a USB drive and then get presented with an option to enter my wireless network password which I can do no problem - mouse and keyboard working at that point. After doing that I can click on a drive icon on the screen which says EFI Boot (there are 2 of those icons for some reason. I have tried booting from both of them.) It then starts to go through the elementary install process and I get presented with a screen to select my language and thats where I am dead in the water. Both mouse and keyboard are unresponsive at that point. I really want try try elementary but am unable to. Any ideas or help much appreciated. Thanks.
