Wireless keyboard conundrum - clues requested!
Hi
My wireless keyboard works with my old iMac (A) but not - now - on my new(ish) one with Catalina (B)
My wired keyboard works properly on BOTH computers.
I've already used Apple Recovery to check (B) with Disk Utility and I've Reinstalled Catalina. I've also disconnected from my power supply and reset the NVRAM.
Help! 😳 ........ please!
iMac 27" 5K, macOS 10.15
