Catalina installation damaged EFI firmware on MBP mid 2012
Today when i run update of OSX to Catalina, when installation initiated restart of mac, it stuck on black screen. I waited 15min and turned it off. After i turned it on, again - black screen. I called to support, tried all "magic button combinations", changed and tested SSD and memory (on my dad's same notebook), tried to disconnect battery for some time (to reset settings, in case of magic keys didn't helped), tried to start with disconnected SSD\CD-rom\Trackpad\wi-fi\... Tested also monitor on another notebook - it works. But with my motherboard when i press power btn - it just turns on fan, and white led always on, and monitor didn't wake up, not "showing black screen" but just didn't turns it on at all, no backlight, no LCD any activity (checked with flashlight). So i went to official local service and they sad that "it's just too old...". So i get to unofficial service but with normal guys, and they tested all the hardware and it works great, but didn't wake up with this motherboard. And they directly programated EFI with special tool, and it works now. So in result - i'm officially say: "Catalina damaged my EFI and it cost me 2 work days and 100$ of repair cost". Is it normal, Apple? You want me to buy new notebook instead of continue using my old one that still working great, so you just tried to kill my old notebook with software "bug"? Or what? Why official support can't help with this case? Why official local services didn't helped?
