In Adobe Photoshop Lightroom in Mac OS, the Map module displays white.

Solutions

Solution 1: Make sure that you're connected to the Internet.

The Map module can be white when you're not connected to the Internet.

Solution 2: Make sure that Lightroom is not installed on a case-sensitive partition.

Although you can install Lightroom on a case-sensitive partition, it cannot be run on such a partition. If it is on a case-sensitive partition, move the Adobe Photoshop Lightroom 4.app file to a partition that isn't case-sensitive.
