Our Mac at home is stuck on OS X 10.7.5, so we're also stuck on an older version of iTunes. Starting yesterday, I started seeing an error message that I could not connect to iTunes Match and trying to access the iTunes Store also gives an error message. I also received a connection error message when I tried connecting using my work PC (Win 7). On that computer, I stay with iTunes 12.6.3 because I use it to backup our older iOS devices that cannot be updated beyond iOS 9.3.5 and offload photos from those devices. I just upgraded the PC to iTunes 12.7.5, and it works. From what I've seen on Apple Community discussions, it seems that Apple has disabled access to the iTunes Store from pre OSX 10.8 devices, as well as older versions of iTunes. Is this something that was preplanned, or did they just switch the setting and cut us all off?
