My Apple USB keyboards certain keys stopped working today connected to my Mac Pro. Space does not work, n does not work etc. I suspected it could have been because I did clean my keyboard today morning, after disconnecting it first. So I waited a bit. Nothing changed. Then I connected my old keyboard, same model, and the same problem persists with my old keyboard as well. But this time it's different keys not working. So I suspected it's gotta be a software issue since both keyboards cannot be broken at the same time. So I attached both keyboards to my MBP. And surprise surprise, the keys do not work when attached to my MBP either.
And now I'm about to go crazy. I rebooted my Mac Pro and resetted parameter ram, didn't help. I booted off from another install of Yosemite to check if it's still somehow software related, nope. So the only explanation is that both keyboards, in the same day, stopped working. Or something happened to the Mac Pro USB bus that it's killing whatever keyboard I'm attaching it to.
