Download of 1.0.2 for Mac OSX always generates "damaged" error and won't run

I have attempted to download the newest 1.0.2 version from the site and direct from Google Code site today and also tried a number of days ago. Download is for Mac and I am running OSX 10.8.2 on a MacBook Pro. Any time I download and try to run the software I get the following error and the app does not load/run in any way.

"'Arduino' is damaged and can't be opened."

I have not had any problem in using many past versions of the Arduino code on Mac and the prior version of 1.0.1 runs ok on OSX 10.8.2.

Anyone having problems with a corrupted download file from the site? Is there something that has changed with 1.0.2 that would cause an error like this ("damaged") in the OSX environment?


This is an issue with Gatekeeper. You probably allowed a previous version of Arduino to run (right-click Open). Now Gatekeeper thinks the Application bundle has been modified and refuses to launch it.

The solution is: Turn off Gatekeeper (System Preferences -> Security & Privacy -> Allow Applications from Anywhere) launch 1.0.2, then turn it back on (whatever your Gatekeeper setting was before).


That was the issue.
Fixed. 1.0.2 runs fine now.
I appreciate the help.
