  • Apple Silicon processors (M1) are not natively supported, however, Realflow can work using Rosetta in Intel mode.

Apple has removed Python 2.7 from the system since MacOS 12.3 and up. That version is actively used by Realflow so we need to provide it to the system. The issue solves by installing the package below. After installing it, Realflow will open again normally. You can also search for Python 2.7 from the official site, if you wish.
