Speaking as someone using a Mac, the "lighting bolt" saved settings have a file extension of ".snap" and are saved in the following folder:
HD / Users / your username / Library / Preferences / com.camerabits.PhotoMechanic /
Then inside various folders depending on which dialog window they belong to. There may be a reason I can't think of, but I assume you can copy the individual ".snap" files to the corresponding location on another computer and that would do the trick. (Copying the entire folder structure might not be as safe though.)
Maybe Kirk will have a better way to handle it.
