Hi, I got this Mac Mini 2012, I did change the HDD with a new SSD, I started to install a new OS, half way something happened it’s stops and I had to restart because won’t install, than I was facing with infinite restart chime, you can see on the video, it shows nothing on display. https://www.youtube.com/watch?v=1P9nuKV0… Anyone can help me what to do? I did try a lot of things like reseting and stuff but non of that works… Help is appreciated.
Ouch! The EFI is corrupted! During the OS install the system was trying to update the systems firmware and during that critical time point you appeared to have restarted the system messing up the firmware. At this point you’ll need to find someone who can return the EFI firmware for you. Do you have an Apple Store near you?
