[LAUNCHER][CRASH] Client always crashes when installing fresh copy

I have been trying to install LoL on my Mac (OSX 10.10 Yosamite) and every time I attempt to let it download and patch it will just crash continiously. I have no idea how I can get around this.

The only way to repeat this is by installing a new client on 10.10. That's the only information I can provide; that and crash reports. (I could only attach 4/6 reports)
