I've tried to install loki on a Macbook 12" 2015, but once the Install screen loads, neither trackpad or keyboard respond.
I've managed to install it without problems on an external USB disk (using rEFInd) using a Macbook pro 15" 2014, in order to use it on both Macs, and after that, if I try to boot it using the Macbook 12", it still doesn't work (no keyboard or trackpad, can pass login screen). However, the macbookpro works flawlessly.
I guess it's drivers related, but I though it would be compatible. Any hint on this? I haven't found much info about it.
