Apple wireless mouse and keyboard will only connect after logging in with USB mouse and keyboard
I have a late-2014, 27" iMac running Big Sur. I recently restarted my computer and noticed that the wireless mouse and keyboard (both apple products) no longer worked. I was able to power down and then boot into a Recovery mode in which both worked just fine. Then when I restarted I was presented with the same problem.
I purchased a USB mouse and keyboard and plugged them in. When I start the computer, the USB peripherals work fine and allow me to login. Once I'm fully logged in the wireless mouse and keyboard work again.
I tried deleting and repairing the wireless mouse and keyboard. I tried deleting the plist files. I tried Resetting the Bluetooth Module.
Has anyone seen this problem before?
Thanks!
