I recently downloaded Yosemite and found that I could not open CS4 Photoshop or Illustrator. When I try, a message comes up stating I must download legacy Java SE6 runtime. I tried downloading this and the newest Java and still the message comes up. I can't get answers from Apple and am now thinking I may have to revert to the old Snow Leopard but don't even know how to do this. Can anyone help? I don't want to use newer versions of CS as I am a retired artist and don't need anything but what I have now.
