Mac Mini 4,1 (mid 2010) - Hardware test unavailable
Hello,
I have tried to run the hardware test on my mid 2010 Mac Mini following various instructions found on the internet:
- restart the computer whilst holding the D key => the mac starts as normal, no hardware test mode
- restart the computer whilst holding the option and D keys => the test seems to start, I select the language then it says the firmware update is unavailable for my machine and gives me the option to restart or shut down
- update EFI firmware (Mac mini (Mid 2010) EFI Firmware Update 1.5) but the installation of it fails as my mac says that this software is not supported by the system
Any suggestions please?
Thank you!
Mac mini, OS X Yosemite (10.10.1)
