is there a way to access the newly launched screensavers from tvOS 26?

Currently no, at least I couldn't find them in the manifests. Maybe they will be live in a future update (but I can't test since I don't have an Apple Silicon Mac or an Apple TV).

macos 26 (i think at least?) is up: https://configuration.apple.com/configurations/internetservices/aerials/resources-config-26-0.plist

I put together a quick script to take their output and give something a bit cleaner to work with: https://gist.github.com/imajes/d62862b132185ac4162ff997025ef42d

@imajes thanks for the pointer; I've updated my wallgrab tool to properly download these resources:

$ go install github.com/kenshaw/wallgrab@master
$ wallgrab list
$ wallgrab show
$ wallgrab grab

Apparently they forgot to put .plist entries for A33A55D9-EDEA-4596-A850-6C10B54FBBB8/0DC99DD8-3386-4D1E-8878-C43E97EB710A, which was causing problems with my script, and has now been fixed.

Quick output from wallgrab, which I just fixed to correctly deal with the missing .plist name:

$ go build && ./wallgrab list --sizes
