after migration to a new macbook i cannot open photoshop. I get error message "you can't open this application "adobe photoshop cs" because powerpc applications are no longer supported"
You cannot run Photoshop CS on a new Intel-based Mac running OS X Mavericks. CS is far too old.
You'll have to buy Photoshop CS6 or Photoshop Elements 12. Or subscribe to CC.
