Moved to a mac six months back, love it. Two of us work on the same mac (macbook pro) using fast switching. (the other person VNCs into the other account). When I fast switch to another account on a mac, the xcode can run in multiple accounts but the iphone simulator does not work. It says "Simulator already in use in another account" I have another macbook (not pro) and it seems to work fine. Does anyone know how to work around that ? or how to fix this. thanks for reading.
