Alas, I have tried, without success, all the solutions/fixes so far presented.

And while joy eludes, my appreciation for the suggestions remains.

Perhaps after these two recalcitrant apps have been updated, things will again be put to right.

FWIW: The two apps to which I refer:
1) iMovie v10.0.8
2) Inerzia Timer v2.3.3.
