Editing Savegame of Icewind Dale: Enhanced Edition, on OSX

Its just a couple of days that we got the Icewind Dale: Enhanced Edition, for the mac.
Its a nice game, and we enjoy it, the only problem is that save game editors for this game (Baldur's Gate save games) are for PC's only.

I found so far that the (windows) program EE Keeper can be run under wine , but it asks for the installation folder. After some trial and error I found that this works very well under OSX :

First of all setup the wine (wine config) so the Z: drive is the root (/) of the mac, then launched the EE Keeper and configure the installation folders as:

Installation Directory: 

Z:\Applications\IcewindDale.app\Contents\Resources\

User Save Data Directory:
Z:\Users\user01\Documents\Icewind Dale - Enhanced Edition\save\

(The game save files are located under the user's Documents)

Also enable the option "Use Custom Save Location"

so simple, as the EE Keeper, just needs to access the Resources files from the game.
