Google’s Nest Hub Max gets Fuchsia update in Preview Program, here’s how to opt in
We’ve suspected theNest Hub Maxwas the next in line to get Google’s nascent Fuchsia operating system since last year, and the wait is almost over. An update for Fuchsia is now rolling out as part of a small test for some of those registered in the Preview Program, who have opted in to test new software releases.
Before you gettooexcited, it’s worth keeping in mind that Fuchsia on Smart Displays doesn’t deliver any big new features. This isn’t like the major Android upgrades we often cover which get released each year, bringing a new look or advanced functionality. This is just an internal change to the OS that these Assistant-powered smart displays run which you may not even notice. That’s because the parts of the software you actually use on an Assistant smart display are cross-platform and built inFlutter, looking and working about the same whether they’re operating on top of Fuchsia or the old Cast OS. It’s still a massive technical achievement to swap an operating system out while keeping everything looking the same, but not the sort of thing most customers will notice, sadly.

The first-gen Nest Hubgot its upgrade to Fuchsialast August, and it was clear thatGoogle was at least considering bringing Fuchsia to the bigger Nest Hub Maxsince December when a comment on the Fuchsia Gerrit indicated (through a code name) that it was being tested internally. Now, around six months later, the update is apparently ready for customers — or, at least, those in the Preview Program.
We’ve reached out to Google for more details, but the company has reportedly confirmed to9to5Googlethat an update that delivers Fuchsia to the Nest Hub Max is now rolling out tosomeof those in the Preview Program — an opt-in testing program Google provides for an early look at new features in Nest and Chromecast devices. The company reportedly says that the update, as expected, will not deliver any substantial changes outside the OS swap. The update’s wider rollout will also reportedly happen faster than it did last year for the1st Gen Nest Hub. This really only leaves theSleep-sensing 2nd Gen Nest Hubto be updated.

The first-gen Nest Hub (originally called the Home Hub) got updated to Fuchsia last year.
Thecurrent release notes for Google Nest and Home speakers and displaysdo not note a firmware change for the Nest Hub Max yet, though those notes are typically only updated once a version is available on all devices, and this update isn’t.

I should stress that Google doesn’t think of the Preview Program to be a “beta” program, merely a way for the curious to get an early look, explicitly stating that it believes that software updates distributed to it are “ready to release to all users.” History doesn’t agree, as these previews have historically broken features customers rely on. In one instance, an update delivered through the program wassoft-bricking speakers. Another time,it interfered with connected devices like smart locks. Updater beware, there are risks associated with this early testing, whether or not Google considers it “beta.”
If you are comfortable with the risk of potentially broken software and willing to gamble that you’ll be one of the lucky few included in the still-tentative rollout, opting in is a simple process.
