Arduino is a unknown developer

Just downloaded Arduino 1.0.2 but my Macbook Air refuses to run the program. This due to being Arduino a unknown developer, it says. OSX 10.8.2
What now?

You’ll have to tell gatekeeper to allow unidentified developers - http://www.maclife.com/article/howtos/how_tweak_settings_gatekeeper_mountain_lion

You can also right (option) click on the Arduino icon and select “Open”. You’ll get a warning message with the option to click “Open”. This will circumvent your Gatekeeper settings for that application.

James - Is that stored, or do you have to do it each time? I haven’t got round to upgrading yet.

It is persistant so you only have to do it once.

Ok. Thanks.

Thanks! Problem solved.
