    Photoshop CS4 Extended

    Philip Reeson

      I have downloaded Photoshop CS4 from disc to a new Mac bought today. Photoshop will work in trial version but if I type the Serial number in it will not accept it. I have wasted ages with Adobe support who tell me that this version will not work with High Sierra yet it works happily in Trial mode. I paid an awful lot of money for this a few years back and rsent being dumped by so-called 'support,' does anyone have an answer as to how I can get this up and running with what Adobe admit is a valid code?
