Hi, I am am changing from a PC to a Mac, I have the photoshop and light room CC version. How do I get the Mac compatible version?
You can download the installer for Creative Cloud from here which is both compatible with Mac and Windows :
Creative Cloud Help | Creative Cloud for desktop.
You can have creative cloud installed and signed in on two computers, as long as you only use it on one at a time. Download and install as you did on the first computer, sign in to your Adobe account on the Adobe website using your Adobe ID, download the Cloud desktop app, then download the software. Sign out on a computer that you will not be using: sign in and sign out of the Adobe Creative Cloud desktop app
