This did work for me just fine. Specifying 9.0.100 sdk version in global.json might help.

[maonaoda]

I used macOS，and the current dotnet is 9.0.1❤️

On Windows, I used Visual Studio Installer and updated to 17.12.0 and I think that automatically updated my workloads. I was able to build new .NET 9 MAUI apps as well as migrate existing .NET 8 apps to .NET 9 successfully.

@jfversluis Can anyone really use it?

Some thing got fixed that the sdk had been upgraded to 18.0.8314 that could successfully install all workload on my own mac.
