Here's the situation:
I have Mac OS X 10.10.1
Next meeting app mac download. I have the Gatekeeper set to only open applications from the App Store and from identified developers. https://universaltree.weebly.com/desktop-netflix-app-mac.html.
Your application will start in the usual way. Following this path, you can open all applications created by unidentified developers, however, bear in mind that you will also be increasing the chance of Mac infection. Back to Table of Contents Allow access to all applications created by an unidentified developer. To override your security settings and open the app anyway follow these steps: In the Finder on your Mac, locate the app you want to open. Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu. Control-click the app icon, then choose Open from the shortcut menu. To open an unsigned app, you need to right-click or Control-click the app and select “Open”. This works on macOS Sierra as well as previous versions of macOS. You’ll be warned that the app is from an unidentified developer–in other words, it isn’t signed with a valid developer signature. If you trust the app, click “Open” to run it.
Preview is my default application for opening pdf-files.
I have downloaded some pdf's which I want to open in another app, (PDFpen, Safari, ..)
(By double clicking on these files they open in Preview without any problems).
I then select the files and use the Finders Show Inspector (or Get Info)-command to change the 'Open with'-app to PDFpen (or Safari or..)

When I then double click on one of the pdf-files I get a warning message: 'filename.pdf' can't be opened because it is from an unidentified developer. (See attached image).
Open App From Unidentified Developer Mac
I then right-click on the file and choose Open With (PDFpen, Safari, ..), and get a new warning message, but now with an option to open the file, which I then do.
After opening the file just once, there is no more problems, I can open the file by double clicking, and it opens in the app I have chosen for that file. BUT this only applies to that particular file. Each separate pdf-file requires the same procedure..
I have seen the same problem on 3 different mac's running Yosemite.
If I export a Pages- or Numbers-document, the created pdf-file behaves in the save manner, but a pdf created by export from MS Word (ver 14.2.5) can be opened in any desired application by double-clicking.
Open App From Unidentified Developer Mac Yosemite Mojave

If you try to open an app that isn’t registered with Apple by an identified developer, you get a warning dialog. This doesn’t necessarily mean that something’s wrong with the app. For example, some apps were written before developer ID registration began. However, the app has not been reviewed, and macOS can’t check whether the app has been modified or broken since it was released.
This issue may happen if you are downloading a known good application for Syracuse University. To override your security settings and open the app anyway follow these steps: https://universaltree.weebly.com/dribbble-app-for-mac.html.
- In the Finder on your Mac, locate the app you want to open. Don’t use Launchpad to do this. Launchpad doesn’t allow you to access the shortcut menu.
- Control-click the app icon, then choose Open from the shortcut menu.
- Click Open. The app is saved as an exception to your security settings, and you can open it in the future by double-clicking it just as you can any registered app.
Note
You can also grant an exception for a blocked app by clicking the Open Anyway button in the General pane of Security & Privacy preferences. This button is available for about an hour after you try to open the app.
