I downloaded the latest version of WireframeSketcher and get the following message:

"To open "WireframeSketcher" you need to install the legacy Java SE 6 runtime.

Unfortunately, this seems to be an older version and Yosemite won't let me install this. Is there a workaround or an update coming for Yosemite?

Hi Phil,

WireframeSketcher requires a Java runtime which was removed by Apple from OS X Yosemite. The fix is to install a Java runtime manually. The best option is to get Java 8 from Oracle as Apple has dropped support for Java 6. You can find Java 8 here: http://www.oracle.com/technetwork/java/javase/downloads/index.html

Let me know if you need more assistance.

Thank you. This seems to have solved the issue.
