[Client] - Loading In Screen (Mac OS)

For the past couple of days I have been stuck at the loading in screen for around 4 minutes (The length of your average song), but every since patch 5.10 I will sit there for quite a while, but the best part of it all...the game will have already been started. No warnings, no firewall issues, but instead the game will actually just go on with you still loading in (initially). This is a major problem as to the Mac players. Ping will be changing, but pct will not be changing. I've lost ranked games because of this and its becoming a very big issue in my opinion so please fix this issue or at least thoroughly test the client on Mac OS just as much as Windows OS's. Please leave a comment on any possible fixes or when the problem will stop being an issue.
