[Mac Client] Bug with Ctrl button affecting all keys. Another bug with External Keyboard.

For context I play on a MacBook Pro

During 5.4, I was playing on the PBE during the 5.5 cycle and noticed a severe problem. Whenever I hold Tab, or Space, or any other key, it was registering as if I was pressing the button over and over. The score tab would therefore blink continuously just as if I was spamming the tab and crazy speeds. This would happen as well with the space bar, blink uncontrollably. Quick casted charging abilities would fire immediately as it was not registering that I was holding the key down but if I was pressing it very fast over and over.

The second issue was related to the Crtl key on my keyboard. If I ever used the Ctrl+Arrow key to switch windows on my mac, it would cause issues in game once I returned to the game window. My mouse buttons were replaced with Pinging and Auto-AttackMove commands. Also the rest of my Keyboard became unresponsive, no keys work, even Esc so i could just leave the game. (I would later find out that only by pressing the same ctrl key again could I revert the change)

I brushed off the situation and ruled it out to just be a PBE issue as there are often many and I was confident it would be fixed and I went back to playing on the live client which did not have any problems. However, once Patch 5.5 rolled out, all the bugs I described appeared in my Live games, but when I went to the PBE, they were gone so i figured they were transferred with the Patch. I have had these issues ever since. I have seen a few sparse reports of somewhat similar issues but they never had any feedback posted to them. It has really been negatively affecting my games. I discovered that the bugs seemingly only occur when I am using my external keyboard that is connected to my computer. Hitting tab, space, or using a quick casted charging ability work perfectly fine from the computer directly. The Crtl related bug however occurs regardless of usage of an external keyboard. I'd like to point out that I used the same external keyboard long before this with no issues until 5.5 came out.

I meet up with a friend who plays the game on an iMac and he said he has the same issues. I have tried repairing, restoring defaults, and reinstalling all with no success. I am fairly certain that these 2 bug situations originated from the PBE cycle just before 5.5 hit live. They were fixed on the PBE but not with the Patch and now I and other Mac Client summoners have this current issue. I had hoped that 5.6 would have fixed this since the PBE was no longer bugged this way for me, but after patching my live client, the issues remained. ANY information that can either help me fix my problem or at least assure that this issue is known and being worked on would be much appreciated.
