I have problems installing a newsreader on my Mac.


First Steps

If you want to install a newsreader on a Mac, you might encounter a small issue.
Here are instructions for avoiding this issue:

When trying to install the Mac version of the newsreader, if you see the message "Programme XYZ can't be opened because it is from an unidentified developer", please proceed as follows:

First confirm this message by clicking on “OK”
Right-click on the file to be installed (alternative: hold down the [ctrl] key and left-click on the file)
Then click “Open”
The message “Programme XYZ is from an unidentified developer. Are you sure you want to open it?” appears
Click on “Open” again to start installation.
