I downloaded the installer from your website and get the following message when trying to open it:
"Install Scout" can't be opened because it is from an unidentified developer.
Actually, I subsequently discovered that I already have the application :) but thought you should know about this issue.
In case others run into an issue with installing Scout, see the first link below on the new Gatekeeper feature in OSX Mountain Lion and Mavericks.
OS X: About Gatekeeper
Ideally, the main developer of Scout would have an Apple Developer ID and sign it with that Developer ID (see following link)
Developer ID and Gatekeeper
hopefully someone finds this info helpful!
thxxxx. It works!
Easiest way is to right-click and select 'Open' -- then the prompt will give you an option to run it anyways, even though it's from an unidentified developer. After you do that once, it will run easily and never nag you again. Brackets has the same issue.
