Does the Apple TV 4K (2nd generation, 2021) Support tvOS 27?
Yes — the Apple TV 4K (2nd generation, 2021) is on Apple's tvOS 27 compatibility list, so it can run the tvOS 27 beta. It shipped with tvOS 14, which means tvOS 27 is another major version running on the same A12 Bionic hardware. The road is getting shorter. One or two major versions beyond tvOS 27 is the realistic expectation now.
Being on the list and getting every feature are two different things, though. The 2021 Apple TV 4K receives the general tvOS 27 feature set. It is the oldest model still on the list, and this is likely one of its last cycles.
How to Install the tvOS 27 Beta on the Apple TV 4K (2nd generation, 2021)
There is no beta profile to download — Apple removed configuration profiles from the process in 2023. Enrol your Apple Account free at beta.apple.com (public beta) or developer.apple.com (developer beta), then open Settings → System → Software Updates → Beta Updates on the Apple TV on your Apple TV 4K (2nd generation, 2021), sign in with the same Apple Account and select tvOS 27 Public Beta or tvOS 27 Developer Beta.
The beta then appears in Software Update like any ordinary update. Download it over Wi-Fi with the device on a charger, and let the first-boot indexing pass finish before judging how it runs. Our full tvOS 27 install guide walks through every step with screenshots.
Apple TV 4K (2nd generation, 2021) Specifications That Matter for the Beta
The Apple TV 4K (2nd generation, 2021) launched in 2021 with the A12 Bionic, 3 GB of memory, a external, up to 4K HDR at 60fps display and storage options of 32 GB or 64 GB. Three of those numbers decide how a beta behaves on it: the chip sets raw speed, the memory decides how many apps survive in the background, and the free space determines whether the installer will even start.
The A12 is now several generations old, but tvOS asks so little of a set-top box that it remains perfectly smooth. Interface animations and 4K playback are unaffected.
What the Apple TV 4K (2nd generation, 2021) Gets in tvOS 27 — and What It Doesn't
Apple Intelligence is not part of tvOS 27 at all — it has never run on the Apple TV, on any model. What the Apple TV 4K (2nd generation, 2021) does or does not get instead comes down to sensors and silicon generation: features tied to hardware introduced after it simply do not appear, and no update will add them.
Everything else in tvOS 27 — the interface changes, the Home Screen and profile handling, the audio and controller support and the system apps — works on the Apple TV 4K (2nd generation, 2021) as it does on the newest model. Our supported devices page covers the full list.
Performance and Battery on the Apple TV 4K (2nd generation, 2021)
Mains-powered, so nothing to plan around. The 32 GB model is the one to check for free space before installing a beta. On the thermal side, the 2021 model has a small internal fan and stays quiet under any tvOS load.
The pattern is consistent across every device: the first two to three days after a beta install look far worse than the software actually is, because Spotlight is reindexing, Photos is re-analysing your library and iCloud is re-syncing all at once. If it has not settled after four days, our battery drain fix guide covers the settings that actually help.
Before You Install a Beta on Your Apple TV 4K (2nd generation, 2021)
An Apple TV holds almost nothing you would miss — apps re-download and sign-ins restore — and it can be restored through a computer if a build goes badly wrong. That combination makes it the safest device in the ecosystem to test a beta on.
Check free space too. A tvOS 27 beta wants roughly 5 GB free before it will begin, which is more than the download size suggests. If you depend on this Apple TV for work, consider whether the public beta channel suits you better than the developer channel.
How to Get Back to tvOS 26 on the Apple TV 4K (2nd generation, 2021)
Turn off Beta Updates in Settings → System → Software Updates, then connect the Apple TV to a Mac or PC with a USB-C cable and restore it through Finder or Apple Devices. Apple TV 4K models from 2022 onwards have no data port, so on those the only route is to turn betas off and wait for the finished release to supersede your build.
If you simply want to stop receiving new betas without erasing anything, set Beta Updates to Off and stay where you are until the finished tvOS 27 release arrives and overtakes your build. Our guide to leaving the beta program covers both routes.
