Adobe Photoshop CS6 MAC OS for older OSs (I am original owner/purchaser

This is an authentic Adobe Photoshop CS6 (MAC OS) DVD. *see photo of back of package for System Requirements I originally bought this in 2012 from Amazon . I installed this on only 1 MacBook Pro that has since been Reset to It's Factory Settings . This software is no longer installed on that or any other computers .  I only ever ended up using this software once or twice.  I do not know much about selling software.  I do not remember if I had ever registered this Photshop with Adobe, or if that was even required.  I searched my email history and did not find any associated with Adobe that I would assume I had received if it was registered. After doing a little research I see that many people state the following: " Please be advised that Adobe Photoshop CS6 will only work on versions of macOS Mojave, Sierra, High Sierra or earlier. It is not compatible with newer versions of macOS ." Also, I saw that if necessary Adobe has the ability to transfer this license if necessary.  I did see that Adobe says it is a long process and may take up to 30 days. You can read about the steps involved for a license transfer on the Adobe site at helpx.adobe.com/x-productkb/policy-pricing/transfer-product-license.html.  I would be happy to do my part in completing this process if you find this necessary. Finally, I have been selling on Pricetronic with 100% positive feedback since 2001 . All sales final, no returns accepted. (I would have no way of knowing if a buyer successfully installed this software and then lied and said was defective and returned disc to me for a refund). -Condition:  see description (above).  see photos. ***You will receive exactly what is pictured!
