Uploading Issue on Mac

Today I got a notification that my Mac cannot open the Arduino since it is not belong to Apple store. I change the Security to accept downloading and running from any source. Now I can't upload on my Arduino and here is the message the I got while I am uploading. Any Idea ?

java.io.IOException: Cannot run program "{runtime.tools.avrdude.path}/bin/avrdude": error=2, No such file or directory at java.lang.ProcessBuilder.start(ProcessBuilder.java:1048) at java.lang.Runtime.exec(Runtime.java:620)

Just another user here. Out of curiosity, what version are you trying to use? I encountered this (or similar) issue with recent 1.6.8 builds, but 1.6.7 worked fine for me.

Edit: The 1.6.8 release works for me.
