Turns out I activated Apple Intelligence on a Mac in Spain (EU). I changed the OS language to English and the region to the US in Settings and I did get through the waiting list in a few minutes.
But most of my shortcuts, Keyboard Maestro macros and other automations are tied to menus and commands in Spanish, so this is going to be challenging. I feel crippled without my usual automations and I’m not going to have time to fiddle with them for a few days.
And the first Apple Intelligence feature I tried (summaries in Mail) does not work because most of my mails are in Spanish and Basque, and a message prompts swiftly: Language Not Supported. Writing Tools only work with text in English.
So I guess I will be turning Apple Intelligence off until Spanish is supported. Or maybe I take a few days to adapt my automations to the language of the Perfidious Albion.
At least I can say Apple Intelligence did turn on the EU.
