That would be my guess as well. I (and others) have had permissions and preferences changed without notice when making system changes in general and/or installing and updating apps. No doubt it all boils down to the plist. If the new install trashes the old plist, of in some cases, creates a new one that is compatible with the new software, then the chances of "inheriting" preferences is greatly diminished.Armageddon wrote:
It should also be noted that I just upgraded to Sierra from El Cap last weekend ... I'm wondering if that has something to do with it?
Here's the thing, are your other files (assuming you have files that are not DP files on your machine... ) from other apps now showing their nasty extensions? I would imagine that's the case and is, of course, easily fixable in the FINDER preferences. In fact, it's the first option in the ADVANCED pane. I also have it off as a default and Sierra didn't change that. I have yet to install D( 9.13 and probably yawn's until I premiere the current project in late May. I will certainly watch to see if that changes on my machine. I doubt it will, but if it does, that DP is doing something to the system. Again, I doubt that, but one never knows, do one?
