Quill0.7.1

Quill signs and notarizes macOS binaries from a Windows computer, helping developers prepare Mac software without moving their work to another platform. It combines these two distribution-related tasks in a simple workflow centered on an existing binary. This addresses the practical problem of handling Apple software requirements when the available development environment is not macOS.

A user working on Windows can use Quill to apply a signature to a macOS binary and submit it for notarization from the same platform. Its focus is deliberately narrow, concentrating on binary signing and notarization rather than acting as a general-purpose development environment. The cross-platform approach is its defining feature: the target is Mac software, while the tool itself runs on Windows.

Quill suits developers, release engineers, and build workflows that produce macOS binaries from Windows-based systems. It is useful when a team needs to complete Mac distribution preparation while retaining an existing Windows-centered toolchain. As a Windows system utility, Quill is intended specifically for this signing and notarization task rather than for writing or packaging the application itself.
