Still waiting riot...If you realized the longer this goes the less I play and the less money I spend....You know a lot of mac users play this game because it is available to them unlike many other games...I dont understand how you would allow a fundamental part of the game like AUDIO and FRAME rate to be broken for so long!
Riotmoonstones4 votesHey!
We are aware of this issue.
On PBE it looks like things were working with no issues, we had folks testing it there. (Testing on PBE is better than testing in-house 'cause it's a cooked build, and more similar to what we would push to live) Based on that, we were fairly confident that this issue would be resolved.
However, that doesn't appear to be the case. (Obviously.)
From what I understand, we will be making a post in Help & Support soon, looking for more information from you guys to help us figure out what the heck is going on. In addition, they should be giving an update with any additional information we have on our end.
nymtheraven1 votesWell, i do have an older computer. I'm running a macpro desktop with dualcore 2.6ghz intel xeon processor, and an older vid card radeon 1900xt. Im running OSX 10.7.5. This is one of the few games I can play cause this comp is old. But it gets my work done! It's a work machine not a gaming machine.
Riotmoonstones2 votesGotcha! Lemme pass on your specs and we can dig into seeing if there's something up with a specific config. :)

after patch 6.8 i can finally play with full sound on without having a horrible fps drop and stuttering sound so thank you riot for that!
Like you have mentioned, it will be wise to make an official post of what the issue is and how riot is resolving as it seems its prolonged issue for many players out there. Also i think players deserve little bit more information of what the root cause was and how it was resolved as many of us went through 3+ weeks of painful game experience. Having said that, thank you again for the great work and hopefully it is resolved for all other players in the future.
FallenWolf113 votesstill having this problem, i feel you man, i posted about this 23 days ago yet nothing. i was looking around other posts about the mac complaints and someone from riot respond expect this user from from the SKINS department saying that the guys in gameplay is aware of it but its been really long since. I hope they didn't just throw this problem out 
prowler traverse3 votesStop calling it a MAC issue. It is also happening to some windows systems as well (laptops from what I've experience/read).
Voidac2 votesDude. You're playing on a Mac. Save yourself the trouble get just don't.
AerialRush2 votesExact same problem, all of a sudden after the last two patches, my FPS dropped significantly and especially during any teamfights now, and the audio is always echoing. It's pretty unplayable. There's also times where the frames will start at 106 or so and slowly drop down to 15 depending on how long the game is going for. We need help!
KSAP2 votesI have been having problems too. :( I have a 2012 MacBook Pro Laptop with a 2.3 GHz Intel Core i7 running 10.9.5 OSX. Still having problems after patching 6.8. Please help if you can, I want to play ranked again. :(
Edit: I did try disabling sounds and I have had minimal fps drops before.

Have you tried disabling in-game sounds? (No) How often do you experience degraded FPS? (never)
