I have read that if you install the Sequoia beta on an external drive, it will not include the Apple Intelligence functionality. Is that true? If so, that is a real bummer because I prefer not to install the betas even on a separate internal volume if it all possible.
Is this true. Might explain my problem. I installed 15.1. Then I went to Apple Intelligence and Siri in the System Settings. I press the button to let me join the Waitlist. I press the "Join Waitlist" but I never get an acknowledgment like I did on iOS and iPadOS. And, the AI features were never downloaded like they were on 18.1 on iPhone and iPad. I run beta software on an external SSD to avoid damaging any applications running in the current released OS on the internal drive. Can anyone suggest a remedy. I did report this issue with Feedback Assistant.
