Cannot open an App from a download Security block

I have an Escort Radar Detector and they now have a MAC APP version to download updates.

Previously I had to use a PC.

When I try to open the Downloaded Application it shows the following:

Escort detector tools can't be opened because it is from an unidentified developers

Your security preferences allow installation of only apps from the Mac App Store and identified developers.

User uploaded file

What do I need to do to accept this, I looked in system Preps but nothing looked like it was applicable to an unlock of an app.

Thanks

I tried to do a screen shot but it did not transfer.

My mind is a blank as I must have forgotten something.

I used Command + Shift and #3 copy to desktop and dragged it to the box, it showed in the box BUT when it was listed on the apple site the Screen shot was gone.

I have done it before can you tell me what I forgot to do ?

Guessing blind: If you are double-clicking and get the security pop-up, try an explicit right-click and select Open. That should get you a pop-up that includes an option to continue the open.

Regards the screen shot: After you have saved it to the desktop (or wherever), and while composing a post, click the "camera" icon in the row of tools above the composition box (hint "Insert Image") and locate the image.

I would not recommend changing that setting, as it significantly reduces security on your machine. Instead, do what markwmsn recommended... after you open it that way the first time, the quarantine flag will be cleared and the app will be considered "trusted," so you can open it normally from then on. Must better to just allow a specific app in this manner than to change the setting to allow all apps!

Never knew it could be opened that way!

Set mine to open anything because I figure I know what I download.

But it certainly is good advice to follow.

Yeah, I didn't know that either for a while... kind of embarrassing when I got schooled on the topic by a relatively new forum member! 😁 That feature was not very well documented initially, but at this point you can find that recommendation here:

http://www.apple.com/osx/what-is/security.html

Look at the end of the section titled "Gatekeeper gives you more control over what you install."
