This is because in 2019. While Photoshop CS6 itself is a 64-bit application, its installer and several licensing components are 32-bit . When you try to run the installer on Catalina or later, macOS simply blocks it. This is the primary reason you cannot install CS6 on any Mac running macOS 10.15 or newer.
GIMP (GNU Image Manipulation Program) has been the classic answer to "what do I use instead of Photoshop?" for over twenty years.

Released in 2012, it was the last version available under a traditional perpetual license before Adobe transitioned completely to the Creative Cloud (CC) subscription model. Because many users want to avoid monthly fees, the search for a "portable" version of Photoshop CS6 for macOS has remained highly active.
First, let’s get straight to the point: There were rumors during the beta phase that Adobe might introduce a portable option, but those never materialized in the final release. Even the reputable team at PortableApps.com has stated clearly: "The license for any version of Photoshop does not allow it legally, and we would not get permission from Adobe even if we did ask."
