My Mac mini M4 is not showing Apple Intelligence on Sequoia 15.5

You should ensure your Mac is fully updated to the latest macOS version (15.1 or newer). Second, check if your system language and Siri language are set to a supported language. Third, Apple Intelligence may require a separate opt-in or waitlist process, and it may take some time for the feature to become fully enabled after joining the waitlist. Finally, ensure you have sufficient free storage space on your Mac, as Apple Intelligence requires around 7GB of storage.

if your Mac mini M4 was purchased in the EU or P.R.China (check the serial number), then Apple Intelligence will not appear — and there’s no solution to this!
