I want to start a petition because the transparency on this issue is lacking. I have been unable to play for three+++ weeks. I played maybe twenty miserable matches before ruling the game unplayable.
TL;DR: Gamebreaking bug on Macs where audio renders 5 times each sound, causing team fights to be about 5 frames. This applies for both 6.6 and 6.7
I know the majority of the community simply won't care about this post at all as it is only a Mac problem. Please refrain from simply telling me to buy a new computer or that I shouldn't be on a Mac in the first place, as this game is designed for both Mac and Windows, they shouldn't neglect the players that own a Mac.
For these last two patches (6.6 and 6.7) there has been a game-breaking glitch on Mac related to audio and frame rate. I can't say I know everything about it at all, but I'll say what I know
Basically what happens is randomly in-game the audio will just go crazy. It is normally almost all game, but if you disable sounds, then re-enable them, you can avoid this bug for the next couple of minutes or so. What I mean by the audio going crazy is that all sounds playing in the game will be played 4 or 5 times, like a ton of echoes happening at once. It makes it quite hard to pay attention to all the sounds going on at once, and after not too long it becomes so unbearable that you're forced to play the game without sound.
The other side of the bug is the frame rate. I believe it is directly related to the audio playing multiple times over, which causes quite a drop in ping as well as frame rate. What I mean is that in every single team fight, I have been averaging about 4-6 fps. Many Mac users I have talked to have also had about 20 higher ping every game because of this. But to team fight in only a couple of frames is a nightmare. Also, think of a 10-man team fight playing at about 5 fps (if you're lucky, I've had it drop to about 2-3 before) with every sound a champion makes playing 5 times. It's not fun.
There is a "fix" for this bug however. But there's a sacrifice you need to make. You have to play the game on the "Disable all Sounds" setting. Meaning you can't hear a single thing that happens all game. That's right. Any helpful indicator of an ability being cast, a teammate pinging that the jungler in coming to your lane, any sound you can think of. Gone. Or you can play team fights on a few frames. You guys realize 5 frames is too slow for the human eye to see motion happening? It's not fun.
I'm sure many people will want to know my system specs. I will say although I have a completely trash computer in desperate need for an update, I know many Mac users with way better computers experiencing this same issue. So I will say I am running OS X El Capitan version 10.11.3 on a late 2008 MacBook. Yes my computer sucks. But this is still a legitimate problem that needs to be a addressed.
