Hello, I have a mac mini late 2014 version. I have tried embedded versions 1.60 and 1.62. I have problems on booting and after that. While I create a usb and the mini is booting succesfully the first time if I shut down the mini then it cannot boot to openPHT anymore. I just have a black screen. Another issue is that if I boot succesfully andleave it on home screen without doing anything it hungs. Nothing I press is worjing. The same usb stick works fine on my PC. Any help?
