I've created a Wine app-wrapper for Troodon80's EE Keeper, and I'm happy to share it with other Mac users out there.
Link to the main EE Keeper thread: http://forum.baldursgate.com/discussion/16497/ee-keeper-updated-to-v1-0-2/p1
Note about OS X's GateKeeper. If you try to launch EEKeeper and get an error saying its not from the Mac App Store and its not digitally signed, then the first time you run it, you need to right click (secondary click) it, and select the "Open" option, and it will ask if you are sure that you want to open the app. Press OK to confirm. After opening the app once this way, you should be able to open it normally.
**Changes for 220.127.116.11a **
- Switched to WineBottler for Sierra/High Sierra compatibility
