I'm trying to install RapidMiner in my Mac, but keep getting this error "

Unsupported major.minor version 52.0". I already installed Java 8, is there any other place where I should look? 

 

Thanks,

    hello @arellano - that's a weird one.  Can you please post a screen shot?

    Hi @arellano,

     

    I assume your JAVA_HOME is still pointing to a different Java version. To check this you can execute 

    <SPAN class="token keyword">echo</SPAN> <SPAN class="token variable">$JAVA_HOME</SPAN>

     from the terminal.

     

    Best,

    Edin

    This is the result of $JAVA_HOME

    Yes, this means that Studio is being run by Java 7 or earlier, while we require Java 8. If you enter java -version in the command line, it should show that it is using Java 8. You probably need to edit your path to make sure that the Java 8 binary is picked up first.
