As starting point before taking some base measurements in preparation for my new DOE for the 'Beths, today I did a soundcard calibration for the Soundcard in my 2015 Macbook Pro. My setup uses a NIST-traceable Dayton calibrated mic (with the mic calibration files for 0°, 45° and 90° provided) and an M-Audio MobilePre mic USB mic preamp.
I ran the Soundcard calibration routine and obtained this result. I think it looks pretty good based on the info from the REW forum...
