So yesterday (or the day before, not sure) I managed to play a couple of League games and that was great, but today I try to open the client and it says the file is damaged and I can't open it. I really don't feel like reinstalling, because last time that took about 21232 million years, just check my last post. I have no idea why the file would be damaged, but it has happened before and I reinstalled every time, but that is such a pain in the ass and so time consuming and maybe there is another way.
Does anyone know how to fix this? I'm on a Mac by the way.
