      With the JRE 7 or 8 installed, the launcher can launch the game using it, by changing the Executable in the Edit Profile menu to the following:

      • /Library/Internet Plug-Ins/JavaAppletPlugin.plugin/Contents/Home/bin/java

      I installed Java 7 on my Mac but the launcher still does not recognizes the Java install.

      The installation path of Java on my mac is:
      /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents/Home

      There is a workarround to start the game with Java 7, what you do is this:

      1.) Start Terminal.app
      2.) cd /Applications (to the location of the launcher)
      3.) java -d64 -Xmx1024M -jar Minecraft.app/Contents/Resources/Java/Bootstrap.jar (as which -d64 forces it open 64 bits)
      And then the launcher will start with Java SE 7

      If you do install Java SE 6 and start the launcher, it will use Java SE 6. But using my workarround you will boot it Java SE 7 (depending on the standard Java version on the Mac)

      Translation of the first screenshot of the middle screen: "To run 'Minecraft', you will nee Java SE 6-Runtime. Would you like to install now?"
