I am trying to install Photo Shop CS6, and it states I need an update to install on Mac Studio.

The last system Photoshop CS6 was compatible with was Mojave, 10.14.6.

So if your budget can't handle the newest version/subscription you might look at Affinity Photos. It's an excellent alternative. I use Photoshop Elemen ts for Mac 2020 and it's does everything I was doing with PSC5 except for converting to CMYK.

FWIW, if you want to use Photoshop, you will need to subscribe to the latest version from Adobe.

Photoshop CS6 is not compatible.
