Chip Compatibility with Screenwriter, Dramatica, Outline 4D, and other Write Brothers applications

Here is a list of chip manufacture compatibility with Write Brothers products:

WINDOWS:

AMD (Advanced Micro Devices) is a manufacturer that makes many kinds of SoC (System on a Chip) processors, and their Intel-compatible processors (known technically as x86-64 (also known as x64, x86_64, AMD64, and Intel 64) WILL BE compatible with Screenwriter 6, Dramatica Pro, and Outline 4D.ARM is a licensing group that licenses intellectual property to fabricators (such as Qualcomm, TSMC, etc).  Any ARM instruction processor (eg Snapdragon) would be problematic for our software: we wouldn’t be compatible with ARM systems running Windows (like the Snapdragon or Cortex processors).ARM processors are typically used in mobile devices, and are presently NOT popularly used to run Windows. We have had compatibility issues on the few ARM-based processors running Windows.The issue with ARM on Windows is primarily one of copy protection / license management, because there is probably x86 emulation on those systems. Dramatica Pro MIGHT run on ARM Windows systems.INTEL systems would of course be maximally compatible.

MACINTOSH / MacOS:

Movie Magic Screenwriter 6.5 (32-bit):  Apple Macintosh running on Intel processors are compatible when running MacOS 10.11 through 10.14.

Movie Magic Screenwriter 6.7 (64-bit):  Apple Macintosh running on Intel or Apple Silicon (M1-M4) processors are compatible when running MacOS 10.15.x through 15.x. (see note 2, below)

Dramatica Story Expert is presently a Mac Intel-only 32-bit-only application, and thus it can only run on MacOS 10.10 through MacOS 10.14. 

Note 1:  MacOS 10.15 (Catalina) and above are 64-bit only versions of MacOS). 

Note 2:  All Apple Silicon processors (M1-M4) REQUIRE MacOS 11.0 (Big Sur) or above.

Note 3: “Apple Silicon” chips (e.g. M1/M2/M3/M4) ARE technically variations on the ARM architecture that Apple licenses, however Apple provides full compatibility with 64-bit Intel Mac apps through their MacOS Rosetta software.

Note 4:  At present, none of our software runs on Apple "A-series" (iPhone, iPad) chips.
