Unplayable Lag on Mac client !?

After patch 6.7 i faced a lot of lag issues. With the release of patch 6.9 it has become unplayable. I have asked various people online and search in the boards also, so its clear to me that its not just me. Its an issue with the mac client. Roit please pay attention to us mac users too. The ping being on the higher ends of 3000 is no joke. Spell and abilities going through 5 seconds after cast ! the lag has forced me to play unranked for the past week now, which by the way if anyone cares is going aweful thanks to this Lag.

Regards, concerned summoner.
