Mac OS Steam client has no access to league mechanic

When launching map from map device - there are no list with monsters, their modifiers, map just starting like as in Standart.

While character is in map already, there are no button at the right bottom corner near skills that is showing current monster's buffs.

Check that please. It's literally a very raw league, while mac players have no access to modifiers and allflames setup, lol.

League mechanic doesnt work for Kirac missions, if thats what youre opening.

I am on mac client as well and have had zero problems with league mechanic on white maps, alch n go, fully juiced, etc.

Try another atlas tree to see if that fixes things for you.
