I used Georeferencer to georeference a jpg map and saved as tif. I used Thin Plate Spline, Cubic Spline, and LZW as settings. The tif shows fine in OSX Preview. gdalinfo reports
Driver: GTiff/GeoTIFF

The QMS in the name refers to QuickMapServices which I was using as a reference instead of OpenLayers. I was using the Mapquest OSM map. I can look at properties in QGIS. I can Zoom To Layer and nothing happens—meaning if I shift the map away from where it should appear, the QGIS map doesn't move.
Where should I look for fixes?
QGIS 2.12.1 Lyon OSX.

You have set the raster CRS to WGS84, but used coordinates from a tile service which might use EPSG:3857.
So you have to set the CRS of the raster to the same CRS to get it working.
Raster -> Projections -> Assign projectionshould do the trick.BTW the corner coordinates are still in EPSG:3857, around the center of Los Angeles:
