Mac OS versions that will run CS5

So, yeah that's an option. Issue for me is every few years I would spring for the full suite, beginning at ground zero. They cost thousands to get all of the apps needed to design what I wanted.

The last suite I purchased was CS5 and as a pragmatic consumer, dad taught me to make things last. Why would anyone buy something that will be unable to work in the near future? 

When I purchased the suite(s), there was never any talk about phasing out the CDs and changing over to a monthly subscription rental. In order to use the fully purchased software I can only use an older computer.

Adobe should offer a program to those of us who plopped down thousands and thousands in their company under the reasonable assumption there would be updates, but not full conversions from ownership to renting. 

This also happens with Quickbooks too. 

And Apple's sales pitch of extremely pricey G5 Towers which will allow for future expansion. After buying three towers under the guise of future expand-ability, Apple no longer pushes this story.  It's called false advertising. Or it is simply changes in technology which should not punish the consumer. 

You speak true. My current Mac is running Mojave and I can run my CS5 Creative Suite on it. Illustrator occasionally crashes, and has a hard time turning images into .png's, but it is doable. I have an old alien trash can mac 2013 and still runs the software decently.
