    Mac Mini 2014 820-5509A Reboot loop while installing macOS

    Hello i have got a Mac Mini 2014 with 820-5509A motherboard it powers on but i cannot install macOS, in first part of installer it goes about 75% and reboots back again to installer
    I think the bios was changed because it has a lot of flux around EFi chip
    Thanks in advance

      MacBook Pro a2141 not installing macOS
      by som_b1
      hello. I have 2141 on which I can't restore macOS. When loading, no buttons are active, it immediately wants to restore the Internet. But then I see an error 2100f. It doesn't boot from an external USB.
      I can't flash it through dfu because I don't know the version of macOS that was on it. Help
      By the way, for some reason it heats up inadequately and the coolers are at maximum

      Vizio TV M50-C1 reboot cycle and static on screen
      by spice_disc
      I'm currently trying to diagnose and fix my Vizio TV (Model M50-C1). I've tried a number of different basic solutions, but I'm trying to determine if my issue is currently a failing panel, T-Con board, or main board (or something else entirely) and whether or not it is worth my time to fix it. Details of the issue and what I've tried are below as well as why I think it is either a bad panel, T-Con board, or main board.

      The Issue: The TV will be on and working fine but after the TV is on for ~5-10 minutes the screen will freeze (with sound continuing) until the TV reboots itself. While...

      A2141 (2019 16" MB Pro) Strange macOS install issues. NAND? WIFI? FIRMWARE?
      by duwane
      Hi All.

      Sorry ahead of time for the text wall. This is a strange problem and I have tried to explain it as best I can. I realise this is a hardware forum (mostly), but I am still not sure if this is even a hardware fault! I am hoping that someone more knowledgeable than me in the area of understanding installation logs, or someone that has had a similar issue in the past may have some ideas of what might be causing this.

      The issue:
      Unable to do a clean install of any macOS versions supported for this model, even after fully erasing and formatting the internal SSD,...

      MacBook Pro 16" (2019) A2141: power consumption? Dead GPU? MacOS not installing
      by tomtom67
      A friend brought his fresh-from-ebay macbook pro A2141 after he failed replacement keyboard plugging.
      I fixed all the little problems he introduced.

      I am unable to install macOS to this device. Both Sequoia and Catalina (from Internet Recovery) start to install, but after ~2-5 minutes into the installation the macbook does a hard restart (max fan spin for a split second, then reboot without chime).

      I noticed what I think is a very high power consumption, like 20V/1.7A when activating WiFi for internet recovery, and more like 20V/3.7-4.1A while downloading the recovery...
