Mac book pro 2019 glitching on dock when I go to shut down, dock goes about halfway down, glitches, and screen turns off. I spoke with apple about it and the had me try to hard reset my computer, which then sent me into a reboot loop that I couldn't get out of. ended up taking it to apple, they said they replaced the whole mother board. it was fine until a few days after... now its doing the same thing. I'm not tech at all and I'm sorry if this doesn't make sense lol but I am frustrated that not even apple can help me.

 
Sorry, but from your text (...or maybe my understanding of it) I do not really get the point...
Maybe you could bring in a little more detail - what exactly is the misbehaviour? What precisely does the dock do when it "glitches" as you describe it? Does it freeze halfway down, come back up again, disappear suddenly, look dysfunctional somehow, ...?
Why exactly does this behaviour cause a problem for you? From what I read, besides having the dock "glitch" somehow (whatever that may mean) you only state about a completely regular shutdown process with a turned off screen in the end, which would be exactly what I would expect from shutdown. Are there any further problems before, during or after the shutdown?

Since Apple replaced the motherboard you should take it back to them and have them figure what’s wrong.

As the previous reply advised, take it back to Apple and let them repair it. Apple warrants repairs for 90 days and if your MacBook Pro has Apple Care that is still valid, they will do the repairs for free.

When this started the second time, had you installed any third party apps or extensions? Did you have any external devices attached to the MacBook when this started?
All I did was update it to the most recent update (it automatically updates) I had it for a day before it started doing this same thing

The 11.2.1 update has been a problem for some people on the forum. When you go to pick up your Mac, go ahead and install 11.2.1. while you are still there to make sure there are no problems again.
 
There is nothing wrong at all! It’s just that your Mac is too fast at shutdown 😉
When shutting down or performing a restart macOS initiates several services to stop background services and uninitialise the hardware. This obviously all happens in the background and the only thing noticeable to the user is that applications are quitting, the dock “hides” (actually quits) and than the background-image-only-screen goes black. This altogether leads to an appearance of a graceful shutdown, which usually it is. Thus users have this visual feedback off “shutting down gracefully”. What does happen in your case is, presumably due to a clean/minimal install with all installations background services (like 4-hour spotlight indexing and things alike), is that the service tasks to terminate applications and processes are finishing so fast, that the animation of the dock disappearing does not have enough time to finish before the shutdown is handed over from the OS to the hardware features (to put it simple the EFI as the hardware’s firmware). This previously happened to me as well and has been for several OS generations around different hardware.

I hope you fin this explanation useful and that you can conclude yourself, that there is nothing to worry about.

I guess the only thing that worried me was the end of the whole thing; the green glitch like across the screen. I guess it isn't that big of a deal lol!

ColorDepth.pngI do not think so. It appears to be some color depth mismatch. You should try resetting NVRAM and SMC.
 
To all, there is now available from Apple a complete macOS Big Sur 11.2.1 installer that contains a fix for an issue where the installer fails to perform a check to see if there is enough room on the hard drive before installing.

The build is 20D75. You can get it from the Mac App Store.
