So after 8 months of 10.1, 10.2 is out. I haven’t downloaded it yet, but I am 99 % sure that the old themes won’t work properly with it. Or not at all. With such new features as user custom icons, there must be many changes in the MAResourcesmapping.plist. That is why.
Correct me if I’m wrong.
To update our themes to 10.2, we must very likely start with the new .plist. Personally, that will take some time. I don’t know yet which of my themes I will update, but I haven’t got time for many. Give me a shout if you are a user of a particular theme, and I will see in some weeks… or months… what I can do.
