I've noticed that for a few days now, on my computer running Mojave 10.14.6, that if I hold any of the modifier keys down, I lose the ability to left or right click, preventing me from using any application that uses the modifier+click combo or selecting multiple items in a list that aren't right next to each other

I use a Corsair K70 Mk.2 keyboard and Corsair M65 mouse with the ckb-next driver, the Magic Trackpad doesn't work for this either.

    As it's not a standard Apple keyboard, the first test would be to swap to one.

  • You’ve introduced not only a different keyboard but, as you state, a different driver. Boot to safe mode with a standard keyboard and see if things work or not. If they do, the issue is with your config.

  • Thanks for your help @Allan, however booting into safe mode did not fix the issue.

I simply fixed this by nuking my drive and reinstalling. Doing a simple in-place reinstall didn't help.
