Apple Releases tvOS 16.4 for Apple TV 4K and Apple TV HD

Apple today released tvOS 16.4, the fourth major point update to the tvOS 16 operating system that came out last September. Available for the Apple TV 4K and ‌Apple TV‌ HD, tvOS 16.4 comes two months following the release of tvOS 16.3.

The tvOS 16.4 update can be downloaded over the air through the Settings app on the ‌‌‌‌‌Apple TV‌‌‌‌‌ by going to System > Software Update. ‌‌‌‌‌Apple TV‌‌‌‌‌ owners who have automatic software updates turned on will be upgraded to ‌tvOS 16.4 automatically.

tvOS updates are often minor in scale, focusing on internal bug fixes and improvements rather than outward-facing changes. The 16.4 update adds a Dim Flashing Lights option that is meant to dim the display when there are flashes of light or strobe effects.

This update adds Dim Flashing Lights, an accessibility option to automatically dim the display of video when flashes of light or strobe effects are detected, and includes performance and stability improvements.

Apple shares information on tvOS releases in its tvOS support document, which is updated after each tvOS launch.

I hope you didn't buy the poverty version without the ethernet port.
The elimination of the Ethernet port on the Apple TV is one of the most infuriating and consumer-unfriendly "upsell" tactics I've seen Apple do to date.

The elimination of the Ethernet port on the Apple TV is one of the most infuriating and consumer-unfriendly "upsell" tactics I've seen Apple do to date.
On the other hand... the difference between the "normal" Apple TV and the "good" Apple TV is only $20.

In my mind that's gotta be the least-offensive upsell that Apple has ever offered. :p

For $20 you get an Ethernet port, a Thread radio, and double the storage. That's really not bad.

Though I gotta wonder why Apple even made the "normal" version in the first place. If they only offered the "good" model at $149, that's still cheaper than the previous generation which started at $179.

¯\_(ツ)_/¯

Ever since tvOS 16.2, my TV won't turn on using HDMI-CEC and makes weird static noises when I turn it on manually after the Apple TV turns it off.

Hopefully this finally fixes it.

Guys, we’ve always complained about large tv libraries taking forever to load in the movies app well, guess what, I have not yet updated my 3rd gen Apple TV HD to today’s release but I’m happy to report that my 700 plus movies library loads in about 3 secs (vs about 30 prior to today). They must have changed something server-side

I've only occasionally been able to control my Yamaha receiver via HDMI-CEC and the ATV remote volume buttons since 16 came out. Setup is a TiVo and the ATV going HDMI into the TV, the TV doing the input selection, then HDMI out to the receiver for eArc and CEC. For a while I thought the magic was to ensure that the TV had selected the ATV as the input before I turned on the ATV, but even that proved unreliable. The ATV remote power button wouldn't turn on the system any more, and holding the power button would turn off only the ATV not the TV or stereo.
I hope this update makes it all work again like it did with 15.

Hopefully they fix the annoying bug where you can't control the soundbar or HDMI CEC-connected sound device in general via the volume buttons (even after trying to learn it over and over).
