Mac Client - Cursor stuck on auto-attack, can't level up abilities, buy anything...

I have seen a couple other posts about this, but no responses have yet to help with this issue.

Frequency: It randomly occurs in game roughly once every 2-4 games. It has happened at any stage in the game (5 minutes in, 30 minutes in, everywhere in between). It also usually occurs after I type something into chat.

The bug consists of the following issues and all occur once it starts:

-Cursor stuck on auto-attack, so anytime I click on the ground it is red and attacks whatever is closest. Once I click something, I don't stop attacking until it dies or I do. -Cannot recall to base -Cannot level up abilities (by clicking or from hotkeys) -When I open the store I have to press the esc key to close it -Cannot buy anything from the store -All abilities are turned on automatic smart cast, regardless of what they were before -If it is still going when the game ends, I cannot click the continue button at the victory/defeat screen.

The only way to fix this is by waiting it out (randomly stops sometimes after 10-20 minutes, other times goes throughout the end of the game) or by restarting my client (which takes an obnoxiously long time).

This has been really frustrating as I figured it was only a patch-bug or something, so I've been waiting it out hoping for it to be fixed. It has been occurring since about the bard patch, and I have given up on even trying to play normals.

I would greatly appreciate some help or like to see if anyone else is experiencing this.

Edit: I have tried uninstalling and re-installing. My client was fine for roughly 15-20 games, then it happened again. Then again 10 games later, then again about 7 games later, now its more frequent.

If anybody has any advice or tips that I can try, I'm willing to do anything. If not, I might have to just say good bye to league for good.
