I am running MAC Os SIERRA and have just downloaded the latest CHIRP.

After decompressing the file and clicking on the CHIRP app. i get the usual security warning that MAC will flag. 

After I acknowledge the flag and accept the software download, when I click on the CHIRP icon nothing happens....no CHIRP !

SIERRA already has the RUNTIME installed so that would not appear to be the problem.

Any suggestions?

Thanks
