Lost my Photoshop (Adobe) License (CS4) when upgrading my MAC operating system to El Capitan and doing a files backup via Time Machine. Went through unbelievable hoops trying to get the Adobe License reinstated. Couldn't manage this; no way to talk with a human or get any kind of helpful hearing from Adobe. Became totally frustrated by the options left to me by the money-grubbing Adobe machine. Did some digging to see if I had access to any alternatives to Photoshop, and discovered Apple App "Affinity Photo". Bought it, installed it, and am in the process of learning the similarities and differences. I am so grateful to the Affinity development team. Your software is amazingly good, and your initial video tutorials are great. You have a sincere fan in this retired University instructor.
