I have tried iATKOS v7 and iDeneb 1.5.1 and both have the same problem. I get to the loading screen then it says loading Darwin/X86 then the computer reboots and tries again. I have tried putting in cpus=1 (and cpus =1), -f -x -v, cpus =1 -v ect and nothing works. Is this a hardware issue or what? I've tried a couple different disks and nothing works. Any help would be much appreciated!!
