I have a Late 2009 iMac High Sierra. It will not allow me to run Photoshop - says it needs OS 10.15 or later. But Can't upgrade to Catalina as Mac too old. Any suggestions on a work around?
You might try the demo version of GraphicConverter or Affinity Photos. See if they will work on an older machine. What Photoshop version do you have? Did you just purchase it.
Your 2009 Mac is now in the obsolete category with Apple. It's time for a new Mac. However, if you get a new Mac many of your current apps will not work as they are 32 bit. You can check to see which of your apps won't work on the newer system, i.e. Catalina or newer, by downloading and running the free GO64 app.

Sorry, there are no work-arounds. You need a newer Mac.
