mi

mi is a graphical text editor for macOS, offered here as the beta variant. Its official beta notes describe features for working with text, code, HTML, and Markdown, alongside project and file-search tools.

• Multi-file search can search across multiple folders; search results can also be displayed in a single-column layout.
• Editing support includes HTML and Markdown modes, with heading display options and an EOF marker setting.
• Git-related tools include repository comparison and settings for the name and email recorded in commit history.
• Other documented features include configurable toolbars, automatic backups, and JavaScript plugins.

Install this beta cask with brew install --cask mi@beta, then open mi from Applications. The beta download page describes the software as free to use, including for commercial use. The official page lists macOS 11.5 (Big Sur) or later and Apple Silicon and Intel support. This cask conflicts with the separate mi cask, so the two variants cannot be installed together. The supplied package is the beta edition, not a stable release.
