Latest Mac OS to run Adobe CS5.1?

[Bob Cole]

Getting a new Mac, and thinking of downgrading my current (mid-2014) MBP so that I can run my bought-and-paid-for copy of Adobe CS5.1.

Does anyone know what is the latest Mac OSX that can run CS5.1?

Thanks.

Hi Bob. As a teacher, I had to beg IT Not to upgrade the OS. I knew that the school would never move to a subscription service for Adobe software. I currently run on Mac OS 10.12.6 where Adobe CS5 and other CS5 products work reliably. I do know that I cannot upgrade to 10.13.
Hoping this helps…
