Here's the situation:
I have Mac OS X 10.10.1
I have the Gatekeeper set to only open applications from the App Store and from identified developers.
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).
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.
