Game works and installed per following:
Purchased game via Steam
Logged into Codeweavers account
Found Banished via What Runs search on Codeweavers website
Started up Crossover on my computer
Clicked on Installation via CrossTie on Codeweavers website
Crossover then took over and ran the installation into a new bottle. I did need to respond to some prompts during the install. During the install Steam was installed and the login for Steam appeared.
When the install via CrossTie was finished, I then logged into Steam which is running under Crossover.
Steam then required another install of Banished which did not take very long. Suspect Crosstie already had the game installed but Steam did not recognize.
Started up the game and runs just like the videos I watched via Steam. Already spent 3 hrs playing.
This is running on a late 2009 Mac mini with 8G RAM, OS X 10.10, Crossover 14.0.1.
Hope this helps. Use CrossTie install.
