‘As we prepare for our next major release of Creative Cloud, we wanted to share some information on updated operating system requirements,’ says Adobe. ‘To take advantage of the latest operating system features and technologies, the next major release of Creative Cloud will not support Windows 8.1, Windows 10 v1511 and v1607, and Mac OS 10.11 (El Capitan).’
I canceled my Adobe CC subscription some time ago and now use combinations of Affinity Photo, ON1 RAW or Capture One, depending on the system, including some very old computers.
