Unplayable 1

After excess joy in the game, I was largely disappointed.
The game is very dim, so that you can not play it.
For example, do not distinguish a tractor in a field is possible.
I have changed and tried the settings in all menus, nothing helped.

I hope that as soon as possible come out an update.

I am in possession of a MacBook Pro 13 inch mid2012, Yosemite.
LS 13 was working fine
