Weird issue happening lately on my Mac Pro. Every 2-3 days when I'm in the middle of something, my keyboard will become unresponsive. Seems like it could be a normal issue if it were a bluetooth keyboard, but it's WIRED and connected via usb. I have to restart my computer for it to start working again. I searched the forums but most threads look like they are for issues on macbooks. Anyone have any ideas for this? Thanks!
