I recently installed LibreOffice Vanilla (LOV) from the Mac App Store. I want it to be the default app for opening .csv files.
First, I tried to open a .csv file using the "Open With" dialog. LOV is not an offered option, so I clicked on "Other" and there it is but it is ghosted until I go from "Recommended Applications" to "All Applications".
That should be it, but I then get this error message (I think from "Gatekeeper"):
If I go into Security Preferences I can make it "Open Anyway", but the next time I try to open a .csv file I get the same error.
How do I set up my Mac so double-clicking on a .csv file will have it open in LibreOffice?
Update: I found a procedure (described as an answer below) that will make LibreOffice the default app for ONE .csv file, but I have to go through the same steps (add LibreOffice to "Open With" and tell Gatekeeper to "Open Anyway") for every .csv file that has not had this done.
So how do I set up OS X so that double-clicking on any .csv file will have it open in LibreOffice?
