*24 Jan 2015* <div class="posthaven-post-body"> Ok, so here's the deal: If you upgrade to \[OSX Mavericks\](https://www.apple.com/osx/preview/), only had JAVA 7 installed, and try to run anything that requires JAVA you will probably get a nice dialog like this one: All my attempts to make Mavericks use JAVA 7 instead have failed so i tried the next best thing: Install JAVA 6. Since you can't find JAVA 6 for Mac at the \[Oracle\](http://java.oracle.com) site, you'll have to install it from here: \[Java for OS X 2013-004\](http://support.apple.com/kb/DL1572). After installing you'll end up with this following structure at the "/System/Library/Frameworks/JavaVM.framework/Versions" folder: drwxr-xr-x 11 root wheel 374 29 Ago 14: lrwxr-xr-x 1 root wheel 10 29 Ago 14:58 1.4@ -\> CurrentJDK lrwxr-xr-x 1 root wheel 10 29 Ago 14:58 1.4.2@ -\> CurrentJDK lrwxr-xr-x 1 root wheel 10 29 Ago 14:58 1.5@ -\> CurrentJDK lrwxr-xr-x 1 root wheel 10 29 Ago 14:58 1.5.0@ -\> CurrentJDK lrwxr-xr-x 1 root wheel 10 29 Ago 14:58 1.6@ -\> CurrentJDK lrwxr-xr-x 1 root wheel 10 29 Ago 14:58 1.6.0@ -\> CurrentJDK drwxr-xr-x 7 root wheel 238 29 Ago 14:58 A/ lrwxr-xr-x 1 root wheel 1 29 Ago 14:58 Current@ -\> A lrwxr-xr-x 1 root wheel 59 29 Ago 14:58 CurrentJDK@ -\> /System/Library/Java/JavaVirtualMachines/1.6.0.jdk/Contents So you might want to fix the path to the current JDK, so that you keep using the JDK 7 by default (Eclipse users, you know what i mean ;)): \$ sudo rm CurrentJDK \$ sudo ln -s /Library/Java/ \$ sudo ln -s /Library/Java/JavaVirtualMachines/jdk1.7.0_25.jdk/Contents CurrentJDK Another thing you might need to change is the JAVA_HOME environment variable but, since that depends on whatever shell you use, \[Google it\](https://duckduckgo.com/?q=set+JAVA_HOME+in+bash) ;) Finally, verify that you are still using JAVA 7 by default: \$ javac -version javac 1.7.0_25 \$ java -version java version "1.7.0_25" Have fun. </div> [[tags/dialog|dialog]] [[tags/error|error]] [[tags/java|java]] [[tags/mavericks|mavericks]] [[tags/osx|osx]]
