2003 Apple Wireless Keyboard won't connect
I have a 2003 Apple Wireless Keyboard (A1016), and of course it doesn't manage to connect to either my 2012 iMac running macOS Monterey or my Windows 11 PC using their native Bluetooth settings menus. I've also tried connecting it directly using Blueutil on the iMac and on a Linux computer, but to no avail. Blueutil, like the native menus, can see the keyboard, but when I try to pair, it just stays endlessly loading without any connection.
Is there any way to make this keyboard work with these devices? Or at least the iMac
