Hello there.
So recently I updated my iMac from 2017 to Catalina. All went well... Yesterday something blew up on the power grid on the street that made a power spike and the power to go out in all of my neighborhood. Sadly I was working and it damaged 2 of my externals HDD (one of them SSD), I think because I was using them at that time (one is the Time Machine and it was backing up, the other is a manual backup I have for my photos that I was organising). The computer seems to be fine. The first time I booted after the shutdown, it crashed with a black screen (didnt reach the logo screen part). But I think that it was because de external HDD were connected. Because I disconnected them, restart and all went well... And since then, no more crashes at boot or in any other places.
But I noticed this "blink" shown in the video. I have no ideia if this was happening before the spike. I'm pretty sure that with Mojave there was no blink. And now I don't know if this is the default behaviour of Catalina booting up or if it was something caused by the spike/power shutdown. And as you can imagine, I'm afraid that my computer is damaged.
So, is this normal? Thank you.
