Ive been trying without success to install Rune on a brand new RPi3. Brand new 32Gb microSD, I followed the 'preparing SD card' guide to the letter (I'm on a mac) but no dice. All I get is a solid red light on the Pi and it gets no further than the rainbow screen. Have tried with a different card and a different Pi. Same result. I have downloaded the latest rune image.
I feel like I'm doing something fundamentally wrong. Can anyone help?
