**EarthExplorer will not currently work with Macintosh systems due to the following:

IE and the Microsoft Virtual Machine does not support LiveConnect for Macintosh systems.
Old versions of the Java Virtual Machine (Netscape 4.6 and earlier) do not support LiveConnect for Macintosh systems.
The Java 2 Virtual Machine does not support the original Java applet security model EarthExplorer uses.
Signed secure applets don't communicate properly through LiveConnect when using the JAVA 2 Virtual Machine on a Macintosh. See http://bugzilla.mozilla.org/show_bug.cgi?id=160274 for more information.
Macintosh users may search for many of the same products at: http://edc.usgs.gov/webglis. You can also access EarthExplorer using the PC emulation package "Virtual PC" if you have this installed on your system
