The Mac keyboard lagging when typing issue has been found on Intel and Apple Silicon MacBook Air/Pro/iMacs with the original keyboard, Magic keyboard, or other Bluetooth and wired keyboards.
I am on a macOS 12.2 on an M1 MacBook Air using the laptop's internal keyboard and trackpad. No peripherals are attached. The problem I started having yesterday is significant keyboard lag. I type a letter, and it does not register at all or is typed after the next letter I type. macOS is also showing the alternate character UI as I type as if it thinks I am long-pressing keyboard keys.
