For all you crazy people like me who can't wait:
Disable SIP (look it up)
Put these two directories in the trash can:
/Library/Apple/usr/share/rosetta
/Library/Apple/usr/libexec
Retore later if you need rosetta (I don't)
Check for update. Loading now!
softwareupdate --list-full-installer didn't work for me. Got errors during install. Try it first though, works for some people
Remove the two directories from trash install.
Renable SIP (look it up)

Hey there! So, I’ve got Tahoe on another volume inside my internal storage, and I also have Sequoia which is my main system. I didn’t turn off SIP, I just deleted those folders on the Tahoe volume from Sequoia. When I booted up Tahoe beta 2, I checked for updates, and guess what? I was able to update to beta 3 without any hiccups!
If you’re in a similar boat, this might be a simpler way to handle it.
I appreciate you all testing this.
I’m not touching this with a 10,000 foot pole.

I hope Apple keeps the rectangular trash can since it looks a lot like the one next to my desk
This is what I did, and it worked like a charm.
1. Downloaded the installation pkg
2. Shut down the Mac, rebooted in Recovery Mode, disabled SIP, and restarted the Mac
3. Deleted the whole ‘usr’ folder located inside /Library/Apple/
4. Restarted the Mac
5. Executed the pkg
6. Started the Install macOS Tahoe Beta.app inside the Applications folder
7. Restarted when prompted
8. Dragged the ‘usr’ folder out of the Trash and back into /Library/Apple/
9. Shut down the Mac, rebooted in Recovery Mode, enabled SIP, and restarted the Mac
10. Done

Wow! 5:24 in the morning in Europe - and at last Tahoe Beta 3 shows up! 10 hours late 
they seem to have re-released it so the delete rosetta workaround won't be necessary anymore:
Following hiccup, macOS 26 beta 3 now available for Apple Silicon - 9to5Mac
Earlier today, an issue affected the Apple Silicon version of macOS Tahoe 26 developer beta 3. Now, it's available for all compatible Macs.
9to5mac.com
not sure if it is a new build as the full installer still has same link
Nothing changed on macOS itself, same InstallAssistant, same ipsw. They only changed the Rosetta stuff.
The whole issue was that they had
The whole issue was that they had
buildVersion where it should be BuildVersion in the list of Rosetta updates. Other people in the AppleDB community identified the problem like 10 minutes after the release, it took Apple a little longer... >_>
You can't possibly be so ignorant as to not understand why a dev would want to test their port against the upcoming version of macOS instead of wasting their time on old releases, can you?
Can everybody please stop their 'not yet here' nonsense. Who cares.
USS Enterprise...it is here, no more not yer here
everything is so much fster

Same here! OTA update is working now. Finally, Apple has listened to our prayers!!! 😂
Lol, ok, so a dev is waiting for a developer preview, 5 years after apple silicon is introduced to port their code? Got it.
Developer previews are to test existing API behavior and to try out new APIs before they hit prod, compiling for arm / Apple Silicon has been available since Big Sur, you can't possibly be so ignorant to not understand that, can you?
