Apple has a list of MacBookPros [0], but I don't know how many of the older models that list 2 gpus on their "Tech Specs" pages need apple-set-os. The original apple-set-os code was posted to the GRUB mailing list in December 2013 [1] so maybe it was in 2013 that new dual GPU Macbooks started needing apple-set-os?
