Bug Report: macOS Not Supported in install_blender

[sumn2u]

The install_blender function in setup_utils.py does not support macOS (Darwin). The function currently checks for Windows and Linux but does not handle macOS, causing an immediate exit with an "Unsupported OS" message.

Affected Code

os_type = platform.system()
if os_type == "Windows":
    file_name = f"blender-{version}-windows-x64.zip"
    extract_func = extract_zip
elif os_type == "Linux":
    file_name = f"blender-{version}-linux-x64.tar.xz"
    extract_func = extract_tar
else:
    print("Unsupported OS")
    sys.exit(1)

Expected Behavior

The function should handle macOS (Darwin) appropriately by either providing a valid Blender package URL for macOS or explicitly stating in the README that macOS is not supported.

Steps to Reproduce

1. Run the function on macOS.
2. Observe that it prints "Unsupported OS" and exits.

Suggested Fix

• Add explicit support for macOS by checking for os_type == "Darwin" and providing the appropriate Blender package.
• If macOS is not intended to be supported, update the README to mention this explicitly.

Additional Context

The issue affects users attempting to install Blender on macOS via this script, leading to confusion. Updating the documentation or the function would improve clarity.
