More importantly ( Adobe support take note) if we are coerced into adopting a software subscription model, one of the biggest (possibly the only) customer benefit is ongoing access to current software. But I fail to see why there is an apparently arbitrary differentiation between two older versions. I can just about follow the argument that software will only work on the latest version of an operating system because it's used sonme of the latest bells and whistles (although - as an IP professional - that's not a great approach to software development). Although it still magically manages to be compatible with 10.14.

What I don't expect is for Adobe (which, let's remember is dependent on the operating system and not the underlying hardware - that's what the operating system is there for) to suddenly decide that its latest software is 'incompatible' with MacOS. Which only cuts it so far since Microsoft manages to accommodate a fair range of hardware. (And yes, I know Apple will plead dependencies on the latest graphics hardware etc. Unfortunately Apple's dubious hardware support policy means that I am prevented from installing anything later than MacOS 10.13.6. It's still perfectly able to hold it's own against current tin. I'm running a 2010 iMac which - despite being 10 years old - is a 2.9GHz Core i7 box with 16GB of memory. The 'upgrading train' is bearable when you have the choice.
