As I told in another question I now have 2 MacPros, One Snow Leo/iTunes 11.4 and Yosemite / iTunes 12.3. As told in the other question, this was in response to my iPhone6 purchase. It won't talk to iTunes 11 and iTunes 12 won't run on Snow Leo.
Now, iTunes on Snow Leo is giving this message -
Constantly. Since I've never synced the phone to this computer, how do I tell it to ignore the phone? It's not one click and done, it keeps popping up. I imagine turning off WiFi on the phone anytime I'm using iTunes can work, but I'm hoping for a better, permanent solution. For many reasons, this is my preferred machine and I need to stick with Snow Leopard.
(I know life moves on. I'm just finding it a bit awful that the phone requires 10.8.5 Mountain Lion. That really caught me by surprise.)
