MacBook Air Update
I’ve tried to update my Mac and it keeps telling me failed. I’m not even able to login to my computer. I wish I would’ve never updated it. I was to just get in and use my laptop without the update.
MacBook Air 13″, macOS 10.13

Hi, and Happy New Year.
I suppose your macOS is corrupted. You should run Disk First Aid to recover your macOS on internal SSD with Recovery Mode.

If it doesn't help, contact Apple Support or make Genius Bar reservation if your local retail AppleStore is open or find opened local Authorized Service Provider to be examined your MacBook Air there.
