Afaik ChromeOS phones home to Google, so if Google is among your threat model (privacy) it's not good.

Las time I checked, installing ChromiumOS wasn't easy and i'm not even sure there's a "ungoogled" version like there is for the Chromium web browser.

I meant, ChromeOS migth be a more secure, not necessarily a more private option.

If macOS had a way higher likehood of zero-day attacks, ChromeOS phoning home wouldn't be the biggest concern to most users.

Because in the first case the threat would be the entire world, and in the second case – only the US government.

Secure is a very vague word, I think you're looking for "less hackable by hostile actors" then definitely chromeOS has a smaller footprint.

> and in the second case – only the US government.

And some percentage of Google employees. Probably not really a big deal, but still there.

macOS now presently phones home to Apple on every novel binary execution, too, as I understand it.

It is also super chatty to the mothership even with iCloud and all updates disabled.

I don’t know how ungoogled it is but it’s pretty damn easy to install CloudReady from Neverware.

It didn't work with my Ryzen laptop the last time I tried sadly

Neverware provides a list of officially supported devices[1], and AMD Ryzen support could arrive with Pixelbook 2[2].

Honestly, compared to installing MacOS, neither is easy

Probably from a pure safety perspective, however since a lot of your life is uploaded to google I'd rather deal with apple. I've used them for years with zero problems other than 1 HD crash, but I always back up my data so that's never an issue. If you're really worried install dockers and use limited user accounts to run apps. There's always a way.

In some ways, yes, but they’re about equal if administered/managed properly.
