Operating system support guidelines for Creative Cloud apps

Creative Cloud desktop apps support the latest operating systems for macOS and Windows, and two prior versions. Most Creative Cloud 2021 apps support Windows 10 versions 1903 and later (LTSB branches are not supported), and macOS 10.14 Mojave and later. 

To learn about the system requirements of each Creative Cloud app, see Creative Cloud system requirements.

We focus our development efforts on modern versions of Windows and Mac operating systems to ensure peak performance and security. Our product offerings are in line with the latest support policies from Microsoft and Apple for their operating systems. For optimal performance and security, we recommend you keep the operating system of your computer up to date.

Follow the instructions for your operating system.

• macOS: From the Apple menu, select About This Mac. The version number of the macOS you're using appears directly below the macOS name. For details, see Find out which macOS your Mac is using.
• Windows: See Which version of Windows operating system am I running?

If you can't upgrade your operating system right now, you can continue to use the currently installed version of your Creative Cloud apps for compatibility until you can upgrade.
