[Mac] Having to double click with certain champions

Hello,

I am having an issue where I have to double click with only left whenever I use LeBlanc or Taric to use abilities.

Another issue is when I am using these two characters "Y" will not function properly(for switching camera views).

When I try double clicking on the shop when I use these two champions, it will not let me into the shop, so I have to double click on my gold amount instead.

I am using a 2009 iMac 21.5 inch with a magic mouse.
