I've just upgraded to SkySafari6Pro from v5 and before that v4 (disappointed, by the way, that there is no discount for upgrading vs a new purchase).
I want to import my custom horizon, which used to work fine, following the recipe in the included help. However, you must have noticed that Apple have changed the way iTunes works for the (very much) worse, so Apps no longer appear there. It is no longer possible to upload the custom horizon via iTunes.
So, what do we do now????
Please help
Found it. It seems that although iTunes no longer allows app management it does still have the file sharing capability, down at the end of the list. I didn't notice it before.
I am using the freeware program CopyTrans App, and I find it easier to use than iTunes.
Yes, the iTunes UI changed so you get at File Sharing a bit differently, but it is still there.
We cannot offer an upgrade discount because Apple does not offer that capability. However we do put the new release at half price for the first month and notify all existing customers to "come and get it". That is as close as we can come to an upgrade price.
