Loading screen gets to 100% then just doesn't load in MAC.

I've never had this problem. My ping is good, my internet connection is good, I've been playing league on my laptop for a year now and this never happens. I straight up get 60 fps when I actually load into the game. Recently it seems like every other game I get to loading screen, get to 100% and then the game just doesn't load in.

This is so incredibly frustrating, and it seems like there's just no reason for it to happen. Disconnecting and reconnecting takes too long, and the game just gets remade by the time I load in again. The explanation I've come across is that the Mac client is bad. Is there anyway I can stop this from happening?
