Hello all, I have this problem with my iMac and a USB-KVM switch (iogear) where the keyboard does not seem to work when I wake the computer from sleep mode. The mouse works. But I have to unplug the keyboard (the Apple one) from the KVM and plug it again and voilà, it works! I could not find a similar problem in the current threads, so sorry if this is a duplicate of one that I could not find. Thanks!
