[GAMEPLAY] UI issues

This has been an issue for a while, i posted about this maybe a year ago with no riot response. When i load into a game i am unable to lock onto my character by pressing Y, so now i have to hold space the entire game to just keep track of my character. I also now have to double click any buttons to do anything in game, be it shop items or leveling abilities. I used to be able to solve this issue by tabbing out of game and back in but now i am unable to even tab out of my game. It's probably worth mentioning that i am on an iMac. If you are a rioter and you see this, please let me know whether or not you are doing anything about this.
