Not sure how things work on the mac so things might be complicated in ways I don't know.
Also make sure you back up any files I instruct you to change just in case you need to reset things.
First make sure that the last profile you used in B&W was the one with the creature you want in CI.
Next you need to find the creatureMinds folder inside your B&W installation directory. In there, there are two files you need.
The first will be of the format C#######.erc. This represents your creature's mind. If you have multiple profiles, then you might have a few files like this. If so, pick the one most recently updated. The second file will be similar and have the same unique number on it and represents your creature's physique, i.e. scars, etc. Copy these two files.
Next, go to your CI installation directory and find the creatureMinds folder there. Find the most recent mind and physique files and replace them with the two you copied from B&W. The copied files have to have the same as the CI files you replaced.
Then start up CI again and see if that sorts things out.
