2 copies on mac

Please direct me to the righ place to ask this question if this isn't it
I've installed 2 copies (legit, I have 2 sets of keys) on different user accounts (this is on a mac) both copies run at the same time, but when I want to go onto battlenet with the 2nd one I get the message: battlenet cannot determine the application version. Does anyone have any ideas on how to proceed? Both installs are new and standard

Thanks for any help
