Hi,
I have been trying to install the arduino IDE on my mac.
I tried in IDE version 1.6.9 and the IDE does not load at all.
I updated the java and mac software versions and tried again to no success (now mac version 10.11.5
java 8.91)
I tried running in 32 bit mode from 'file info' again no success
I tried a few other versions (1.6.8, 1.0.9 and the recent hourly build) again with no real success

After more searching I found version 1.6.1 (https://www.arduino.cc/en/Guide/IDEonRecentMacOSX) which seemed to be built address the problem. This is the most successful version so far, the IDE loads. When I try and upload a sketch however i get the following.
"Cannot run program "/Applications/Arduino.app/Contents/Java/hardware/tools/avr/bin/avr-g++": error=13, Permission denied"
As requested in the 1.6.1 page I have raised this issue.
Could you give me some advice on how to resolve please?

Thanks
