Rosetta problem

[octav]

Hello!
I'm trying to install Rosetta on Tahoe 26.4.1 using Terminal. Always answer "Rosetta 2 update is not available".
Macbook Air M5.
Please help!

Maybe no update is available, because it's already installed?

What happens if you just launch an Intel app? (Or check the box to use Rosetta on a Universal binary.)

No, it can't find it using search, and there's no checkbox. I open the old program—it prompts me to install it, then says "no connection"

Weird. Are you signed into Beta Updates? It may be some temporary issue with Apple's servers, or the software update catalog.

Apple is not permanently dropping support for Rosetta until MacOS 28.

What region are you in (geographically)? Apple pulled Rosetta from certain regions as far back as macOS 11.3, and I don't know if they ever put it back.

Do we know which regions? The linked article doesn't say.

Thank you very much! It works!!!)

I wanted to install a Rosetta that would emulate Intel emulating PowerPC emulating Motorola 68000, but I couldn’t get it to work.

Get Rosetta pkg links directly from Apple, in Terminal
- for all macOS builds

curl -sfL "https://swscan.apple.com/content/catalogs/others/index-rosettaupdateauto-1.sucatalog" | plutil -p - | awk -F'"' '/"BuildVersion" =>/ {build=$4} /"URL" => ".*RosettaUpdateAuto[.]pkg"/ && build != "" {print build; print $4 ORS; build=""}'

- for the macOS version you are running

curl -sfL "https://swscan.apple.com/content/catalogs/others/index-rosettaupdateauto-1.sucatalog" | plutil -p - | awk -F'"' '/"BuildVersion" =>/ {build=$4} /"URL" => ".*RosettaUpdateAuto[.]pkg"/ && build != "" {print build; print $4 ORS; build=""}' | grep -A 1 "$(sw_vers -buildVersion)"

macOS Tahoe 26.4 has introduced a nagging message about "Support ending for Intel-based apps". The message appears when starting x86_64 apps on macOS Tahoe 26.4 and above and can be disabled with a configuration profile.

"allowRosettaUsageAwareness
boolean
If false, disables Rosetta usage awareness. When Rosetta usage awareness is active, a pop-up dialog is displayed to the user when an app that is using Rosetta is launched. The pop-up dialog indicates that Rosetta will be removed in a future version of the operating system so that the user can contact the app vendor regarding a replacement for the current app.
Available in macOS 26.4 and later."
