How do you open a mansion in the level builder?

For a number of months, the Level Builder will remain as-is, and be a separate download. As-is means: requires Rosetta to run on Intel Macs. And you must open the original format of the mansion to edit it. Then you

export

the mansion to the HD format to play it.

You can't open mansions that have been exported. To open them, you must open the original file and edit it, and re-export.

I looked up secret counts for you though.:

Tomb of Princes Easy - 12
Normal - 17
Hard - 28

Does this mean that players with OS X 10.7 (Lion) will not be able to build and edit custom mansions until the builder is updated? And how will the

export

be done?
