Download MDZip Studio 1.7.0

Added
- MDZip Studio for macOS. One .dmg runs natively on Apple Silicon and Intel Macs (macOS 12 or later). The app isn't signed by Apple, so the first launch needs System Settings → Privacy & Security → Open Anyway; the README has the steps.
- Homebrew: brew install --cask mdzip-project/mdzip/mdzip-studio, upgrade with brew upgrade --cask mdzip-studio.
- On Mac, .mdz files open in Studio by double-click and show the MDZip document icon in Finder. Studio is offered under Open With for .md files without taking over as their default.
- Mac menus: an MDZip Studio app menu (About, Check for Updates, Hide, Quit), a Window menu, Reveal in Finder, and ⌘ shortcuts in menus and tooltips. The menu follows the focused window.
- Mac Dock: open files by dropping them on the Dock icon; the Dock menu has New Markdown Document, New MDZip Document and New Window, and recent documents.
- Check for Updates on Mac downloads the new .dmg to Downloads and opens it, for you to drag the new app to Applications. Homebrew installs are told to run brew upgrade --cask mdzip-studio instead.

Not on Mac yet
- The Explorer preview pane has no Quick Look counterpart, and Make default Markdown editor is Windows-only (use Finder's Get Info → Open with → Change All…).

Installing on macOS
macOS: download the .dmg and drag MDZip Studio to Applications. The app is not signed by Apple, so on first launch click Done on the "Apple could not verify…" dialog, then open System Settings → Privacy & Security and click Open Anyway. Or run xattr -dr com.apple.quarantine "/Applications/MDZip Studio.app". Homebrew: brew install --cask mdzip-project/mdzip/mdzip-studio (upgrade with brew upgrade --cask mdzip-studio).
