Loading Please Help This Mac User

For the past I think it has been 5 games I have kept getting this response on my loading screen (this is a custom game to test it's consistency) Ever since a small update in the client the past day I have kept getting this message and loading late into my games. I do use a Macbook Pro. This never happens until now, and I have checked my connection which is stellar. Please explain why this is now recently happening, I don't think its on my end but any help would be great.
