A published bottle is a bottle that is available for use by all users on a
system. These bottles are stored in the
/Library/Application Support/CrossOver/Bottles folder and can be copied or
deleted but not modified. A private bottle, by contrast, is a bottle which
is stored in a single user's home and can be accessed only by that user.
Any user may run the applications in a published bottle. All files that are created or changed during use are stored in that user's home folder and do not affect other users on the system.
For example, if a user wants to install Internet Explorer and then provide it for use by other family members, he or she would install Internet Explorer into a private bottle, and then publish that bottle. Subsequently, other users can run CrossOver and launch Internet Explorer without engaging the bottle manager or installing anything.
Once a bottle has been published, it cannot be modified. In order to modify a published bottle it is necessary to make a private copy, modify it, and re-publish. Any copy of a published bottle is automatically made private.
