Trouble downloading Earth EC or Earth Plug-in to a Mac

Macs that run OS X Mountain Lion do not yet list the Google Support Portal as an identified developer, so they place Portal downloads in the trash as a quarantine measure. If you download Earth EC or the Earth Plug-in from the Support Portal to a Mac running Mountain Lion with security set to maximum, you'll need to move them into the appropriate directory after download. For more information, see Apple support.
