Photoshop CS4 no longer works on OS 10.13.1?
I recently upgraded my iMac to 10.13.1 and I can no longer use my CS4 Photoshop program. I can open the application, but cannot load a photo, or use any of the drop down menu. All options appear grey. Is this CS4 no longer compatible with my new OS?
iMac, The OS is High Sierra 10.13.1
