I have attempted to download the newest 1.0.2 version from the arduino.cc 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 arduino.cc site? Is there something that has changed with 1.0.2 that would cause an error like this ("damaged") in the OSX environment?
