John Gruber:

Last week Marco Arment tweeted this screenshot of a glitch/bug in the Finder on Catalina: he selected a folder full of multi-hundred megabyte files and the Inspector panel showed the folder size as “Zero KB”.

Clearly that’s wrong. I know from talking to Arment privately that about 30 seconds after he took the screenshot, the Inspector updated to show the actual folder size. But that’s still very wrong. The Finder should never show inaccurate information regarding the state of the file system. Never.

This a one-off? No.

Moltz mentioned a similar problem I’ve seen too: you put some large files in the Trash, then empty the Trash, and the available space shown in Finder windows (View → Show Status Bar) doesn’t change at all for an indeterminate amount of time.

In my Catalina life, I’ve got no shortage of similar examples. Is this about Catalina? About APFS? Or (and this is the answer I favor) is this about the current state of my Mac’s dependence on iCloud?

If the move to iCloud is contributing to latency in Finder reporting (speculation on my part), what path should Apple follow? If you launch an app that automatically opens a file that’s been offloaded to the cloud, what else can the app do but wait for the file to be returned to earth? Does the Finder depend on some iCloud reporting to paint an accurate picture of the file’s size?
