[GAMEPLAY] MAC - Left click functions, not working correctly.

Computer Specs: iMac (20-inch, Mid 2007) Processor: 2 GHz Intel Core 2 Duo Memory: 4 GB 667 MHz DDR2 SDRAM Graphics: ATO Radeon HD 2400 XT 128 MB Credit card details: 69696969696 Pin number: 420 ( Yes my computers a mac, and yes my computers from 2007, yes i use the lowest graphics (it can handle medium graphics at 30 fps but it drops below sometimes, and yes it's super old and outdated)

It happened Wednesday 17th November 2015 (GMT + 10.00). Started a duo queue with a friend of mine.

Upon starting up i decided to pick singed top lane and try him out in the new Season. However upon spawning, I was

• Unable to open the shop using left click.
• Unable to use left click to select a target to teleport to.
• Unable to left click map, to quickly view selected area.
• Unable to select enemy or ally champion with left click, to view stats.
• Unable to buy items in shop by left clicking icon, however i can if i select the item with right click, and then left click the buy button.
• Unable to ping holding "G" and then left click drag to ping.

I can however....

• Use left click to manually level up skills
• can use left click in options menu.
• Can use left click on settings/anything HUD related.

RECREATE:

1. Play on my shitty mac
2. Open league and login
3. Enter game picking any character you want
4. Try use left click functions and fail

Gotten this issue 6/6 times (5 custom matches, 1 normals)

This is most likely a problem on my side, however i've heard a few others get this bug, however it just "fixed itself" after 1 game..... Mine however hasn't thus i would like the help of a riot Employee or someone who can help with this situation.

Thank your for your time. Sincerely.
