Welcome to the Pentax Forums!
Sorry you are having such problems with processing RAW files from your K-70. Until you get full support from your tool of choice (e.g. Adobe Lightroom), working with RAW can be challenging. I am surprised you had quality issues using the embedded profile from the DNG. The profile contains tone curves and color mapping information and is not involved with sharpening or noise reduction.
As you found out, the DCU software will work, but behavior and installation on Apple products can be a source of frustration. In addition, the tool is fairly primitive. As you have discovered, conversion to TIFF is an option, but does result in loss of maker-specific stuff. If you want to apply lens corrections, do it in DCU prior to exporting as TIFF.
Adobe camera profiles are sort of a strange thing. The DNG specification requires an embedded profile. With camera-generated DNG, this is created by the manufacturer and is often fairly minimal. The eventual "Adobe Standard" and other profiles are the result of collaboration between the manufacturer and Adobe. These usually trail the camera release by a couple of months and are generally an improvement over the embedded version. That being said, there are some users that prefer embedded. To each their own.
Things could be worse...You could be using a camera that does not support DNG.
