I've been trying to diagnose a problem with my Logitech K120 keyboard paired with a Macbook Pro 15" (Retina, 15-inch, Late 2013) where occasionally, pressing the caps lock would cause that keyboard to completely stop responding for a few seconds. I'd previously used this keyboard with a Windows PC, and found no issues.
I've tried the following:
- Setting the modifier key to do nothing and then setting it back (per this Superuser answer)
- Installing Karabiner Elements (from the same Superuser thread. This actually makes it worse, in that when the keyboard freezes the computer, it never unfreezes until I kill Karabiner
Has anyone encountered this before? I might just try replacing the keyboard soon, but I was hoping there'd be a software or configuration fix that would work.
