Hi all, I am trying to use Carbon Copy Cloner, I downloaded it and when I tried to open it, a window pops up with a graphic of a stop sign (but no letters on the sign) and it tells “Carbon Copy Cloner has not been signed by a recognized distributor and may damage your computer. You should move it to the Trash." Cancel and Move to Trash are the only options it lets me do on that window. This has happened with a couple of programs I downloaded to run on my MacBook Pro (early 2011) but every time I try to run it that window pops up and I cant run it? Is there something I can turn off that will allow me to run programs of my choosing, not just the ones that my MBP approves of? It's driving me nuts.
