Kev Quirk writes about how he broke macOS by deleting a single folder on his M1 MacBook Air.

I go through my usual routine – boot my M1 MacBook Air, plug it into my dock so it connects to my screens and peripherals, then head into my first meeting of the day.

But something is wrong…

The panel at the top of the MacOS screen is missing, and the MacBook feels really sluggish; which isn’t like an M1 machine at all – these things are rocket ships.

Spoiler! It’s not his home or user folder.

I wonder if this is related to a certain macOS feature that backs up your data into the cloud to free up storage space locally.
