It should. I have an iMac and using the latest updates of LR and PS. As far as I know way back version 2(around 1993) when i started using Photoshop, PS is only for Mac.
I was referring to the NIK collection plugins still working using the latest updates to PS and LR on a Mac. I saw a few people mention that NIK was still working on their Windows machines. Because I read it was only compatible up CC 2015 but have heard others had it working in CC 2017.
