I follow this guy guide
But, at the moment I select the efi boot icon, the mac freeze and after a couple of minutes, reboot and enter in osx
Same here! I also tryed it on my IMAC 2006. I also tryed different USB Pendrives but always the same result. It freezes and after a couple of minuts it restarts into so Main OS. Any tips are apeceated.
Considering the release date of the video batocera 5.23 or 5.24 etc. I think you are using an older version. Please try the older version.
