I'm using the latest version of Adobe Photoshop. Now I have switched from Windows to Mac and would like to know how I can use the program on the new notebook?
Depends on. Do you mean latest version CC?
Then the key is valid for both.
My condolences to the switch
You can download Photoshop from your Adobe Cloud again and then log in to your new computer with your Adobe Creative Cloud account should work. For me it also runs in parallel on both operating systems!
