The firmware update worked after I disconnected ALL periphericals with USB or Firewire. Especially an extarenal HDD seems to be the trouble maker. Aftet the update mac mini started properly again. I shut it down, reconnected all devices and the problem reappears. The mac mini stucks with a white screen. Now, finally, did “Mac mini EFI Firmware Update v1.8” show up in Software Update. Installing this bumped the Boot ROM to MM61.0106.B09, and installing “Mac EFI Security Update 2015-002” (which says it requires OS X 10.9.5) using the same Terminal technique described above bumped it to MM61.0106.B0A. MM11.0055.02B 'Mac mini (Intel) Firmware Update 1.0' MM11.0055.03B 'Apple Mac mini (Intel) Firmware Update 1.0.1' MM11.0055.B08 'Mac mini EFI Firmware Update 1.1' Another suggestion: is it possible to dump a entire firmware from a real mac? I've begun googling about this and here is what I found.
