Joe Rossignol, MacRumors:

Alongside the redesigned iMac, Apple introduced a new Magic Keyboard with Touch ID for fingerprint authentication, which is useful for quickly logging into macOS or confirming an Apple Pay purchase online.

And:

As first noted by Rene Ritchie and confirmed by MacRumors, the Magic Keyboard with Touch ID is fully compatible with all M1 Macs, including the new iMac, 13-inch MacBook Pro, MacBook Air, and Mac mini. If used with Intel-based Macs or other Bluetooth devices, the Magic Keyboard will still function with the exception of Touch ID.

Here’s that Rene Ritchie tweet.

I do all my Loop posts using the previous gen Magic Keyboard. I love the feel of the keys, don’t really mind the squished together arrow keys, the price you pay for a compact, portable keyboard.

Telling that Apple stuck with Lightning for charging and initial setup. Feels to me an indicator that Lightning isn’t going away anytime soon.

If you’ve never used a modern Magic Keyboard, one of its charms is how ridiculously easy it is to pair. Just connect its lightning port to your computer, make sure it’s turned on (the previous gen have a tiny slider switch in the back, green means it’s on) and that’s it. A notification pops up to let you know it’s connected. No need to plug it in again until it runs out of juice.
