So many coincidences because coincidentally... that lady ordered a new keyboard which arrived yesterday as well.
The whole story is... her keyboard did not work well anymore, the 's' was broken. She used her built-in laptop's keyboard for the 's'. Ridiculous, I know.
A year ago, yes, over 12 months ago in fact... I told her to wait with ordering a new keyboard because USB-C ones were imminent. That is how long this USB-C peripheral rumour has been circulating.
She waited for a whole year to order one... When she finally did I hooked up my 2021 keyboard with Touch ID to see if that'd work... which it did. We thought it was a 2018 MacBook Air.
Then I heard on Accidental Tech Podcast that the new 2024 keyboards would only work with macOS Sequoia 15.1... which seemed absolutely bonkers to me. So I got worried, went to her laptop yesterday to really check the model and it was an M1. I was happy it'd be upgradeable to macOS Sequoia, because she was still running Sonoma.
The keyboard arrived yesterday and yes... it "worked", but as you said U69... none of the function keys worked. How is that possible? Apple should really really fix that. It's madness to think that their own keyboard doesn't work except for with the absolute latest version of their OS? That is ridiculous, Apple.
She updated to macOS Sequoia and it worked. But after a year of waiting it was unnecessary stress about something as simple as a first party keyboard.
What does one do if their slightly older intel Mac's keyboard breaks, I wonder. Only some of the late intel-period Macs support macOS Seqouia. I very much hope that Apple will backport to macOS Sonoma and Ventura whatever is needed to make their own Apple keyboards work with their own Apple computers .
