There is a point at which nearly all companies stop offering direct support on outdated versions. You might try getting support from Microsoft for Win 7, for example. You'll be referred to more or less static knowledge bases, and not much more. That Adobe will give some help, as difficult as it may be to reach, is not common among major software makers. And again, this is very old software in a very fast-moving segment.
CS6 will not run on any newer Mac at all, since the OS no longer supports 32-bit software. (And there are more people than you unhappy with that hard shift in support.) If you want to run a ten-year old system with over ten year old software, your only option is to freeze the whole system in updates. You can't move forward to a new OS and keep old software. At all.
CS6 can be made to work on a Win7 system, with some compatibility settings addresses. It's variable as to whether it can be made to work well, with all features functional, on anything later. There are some folks here who know the very specific ins and outs. (It's unlikely Adobe support can give you more than a few boilerplate suggestions; they simply don't support old sofware on new OSes, and are far from alone in that respect.)
If none of the "old wares" folks here jump in, I will ping them to see if they care to offer answers.
