I'm trying to triple boot my MacBook 15,1 using these instructions. I have of course mac (latest) and windows booting but I'm failing to install latest Elementary OS.
I burned the iso to a usb stick. That boots fine and I can launch the installer. But the installer does not list the mac's SSD drive so I can't finish partitioning the empty space and install linux.
The only disk the installer shows is the USB stick.
Any ideas how to solve this?
