Arduino will not run


I have just had an upgrade on my mac and the arduino software will not run. I have just upgraded to the latest s/w and get this message.

“Arduino-2” can’t be opened because Apple cannot check it for malicious software.

It then tells me to contact the developer for an upgrade.

I have no idea whats happening as it ran perfectly well before, though I have not used it for some time.

Can anyone help?


Cmon Mike you should know to look around and see if anyone else has similar issues.
Which they do thanks to APPLE

There have been a few fixes mentioned for apples dropped ball.
