But before I consider dual-booting the Mac, is there a good way to verify I can trust my i1d2? 

Does it have an ambient light adapter ?

If I point my i1d2 with the ambient light adapter on at a standard
tungsten incandescent globe (color temperature nominally that of 'A', about
2870 K), and do an ambient reading (ie. spotread -a -x), I get the following:

 Result is XYZ: 1087.581794 939.634246 272.759751, Yxy: 939.634246 0.472867 
0.408541
 Ambient = 2951.9 Lux, CCT = 2513K (Delta E 5.610268)
 Closest Planckian temperature = 2566K (Delta E 3.186191)
 Closest Daylight temperature  = 2245K (Delta E 2.133122)

How does your's compare ? Is it's color temperature and xy values
similar ?
