I downloaded the Scala IDE for Mac 64 bit from http://scala-ide.org/download/sdk.html
I open the program, click File > New and see .
The Coursera tutorial I'm in says that I should see the option to create a new Scala project. It looks like I have the IDE but not the SDK?
The simplest reason to get this behavior would be if all perspectives are closed.
Most of the menus in Eclipse are contextual, and File > New is empty if there is no current perspective.
To open a perspective, use Windows > Open Perspective > Other..., then select Scala and OK. Then File > New contains the list of the Scala related wizard.
