Hackintosh - Apple Music (Lossless) Issue
By - Impossible-Ear7504
I don't have a fix, but I am having the exact same issue. Hoping someone else can respond with a solution other than disabling the internal graphics.
If memory serves, iMacPro and MacPro7 are both Xeon, so no Intel Graphics...
the nuclear option would appear to be to remove discrete graphics entirely and see if everything works (as iMac19 or less).
ummm, I thought you could purchase non-DRM music from Apple now???
what's the deal?
hmmm, it appears that you could at one time get DRM protected lossless from Apple. (ALAC)
There is a lot of software that play ALAC files, give them a try and see if it is just iTunes -> https://en.wikipedia.org/wiki/Apple_Lossless#Software
