Custom game issues on Mac

I am using a late 2016 15" Macbook Pro and when in offline mode I cannot create a custom game and just get an “Error” pop up window with no other description.
When I try to create a 1v1 custom game while online, the lobby doesn’t populate correctly (doesnt show that I’m in it) and when I try to add a computer to an open slot, it kicks me out of the lobby.
I’m also not able to start any custom games when I’m the host it just kicks me back to the menu.

Same error here!

Please someone provide some solutions

What worked for me is i deleted the map folder for WC3 then restarted everything. Next boot up it worked great
