The latest version of the Mac os, when you run a program in Yosemite and the error message does not run up. Can I know why?
Please send the exact wording of the error message, maybe someone has seen the same thing and has an answer. It is most likely related to security though because they keep adding stricter security to OSX.
One thing you can check is if in the System Prefernces-Security on the “General” tab that the “Allow applications downloaded from:” is set to “Anywhere”. The default setting is “Mac App Store and identified developers” which will block the software and give you an error that does not describe what is really happening. Apple only reports that the program cannot be opened when you try to run it.
