Can’t be opened because it is from an unidentified developer
When I try to install a Native Instruments download product on a Mac OS X v10.8.x I encountered an error message attached below. How can I prevent this error message? I downloaded this product again so that I may fix this issue but nothing happened. Can I get a suggestion to resolve the problem?
Thanks to you.
