mouse and vision problems

Ever since I updated in mid-August I’ve had mega problems trying to play LOL. ( I am on a MacBook.)

Problems: • Y key doesn’t work • Can’t use mouse to move the camera. Must play on camera lock. This is the problem that bothers me the most. • Must left triple click to enter store • Must left double click to buy items • Must left double click the “x” to close the store window • Must double click to level up • Must double click to use abilities and then there is a long lag

I can click on the map though it must be a double click for left clicks.

These problems disappeared for just one game but then they came back.

Maybe this information will help to diagnose my problem: I removed and then reloaded LOL (it took a REALLY long time) but same problems persist. I bought a new mouse - still have same problems. I have logged in on under a different account - still no relief.

I hope someone can help me.
