Install Presspeech from https://github.com/rcourtman/presspeech on this Mac.

Before choosing an install or launch path, verify the published macOS version on https://github.com/rcourtman/presspeech/releases and the deployed https://rcourtman.github.io/presspeech/install.html#direct-download guide. Use the version-pinned download only when both identify the same available release; if they disagree or the release asset is unavailable, stop and wait. The source branch, release notes, and local site metadata can be ahead of the downloadable build. Do not infer publication from those files alone.

Before installing or launching, explain the model download. Presspeech downloads its local speech model (~500-600 MB) from Hugging Face; the public model needs no account token, and from 0.3.9 Presspeech removes inherited Hugging Face account tokens from its model requests. Model downloads do not include dictation audio or transcripts. Valid inherited lowercase `https_proxy` or `http_proxy` settings still route model requests: a TLS-inspecting proxy trusted by macOS can read them, while a tunnelling proxy cannot. If the user depends on a proxy whose trust is unclear, wait. From 0.3.9, Presspeech refuses to start if either setting is malformed, naming only the variable; the user corrects or removes it before relaunching. Downloading the ZIP or installing the app without opening it does not make the model request. On a clean install, Setup waits for Download Model or Set Up Later; an existing installation with a missing model may start a download on launch. Do not inspect or display token values or proxy values, change credential settings, share logs containing them, or launch without the user's informed choice. If the user chooses to wait, skip the `open` command below and leave the app unopened. See https://rcourtman.github.io/presspeech/privacy.html#network-calls.

Before downloading or installing, run these read-only compatibility checks:
  uname -m
  sw_vers -productVersion

Stop if the Mac is not Apple Silicon (arm64) or macOS is older than 14. Do not download, install, or launch Presspeech on an unsupported Mac.

Presspeech has two notarised install paths: a direct release zip and a Homebrew Cask. After the compatibility checks pass, check whether Homebrew is already available:
  command -v brew

If Homebrew is available and the user chooses it, install with:
  brew install --cask rcourtman/presspeech/presspeech

Otherwise offer the direct notarised zip using the current version-pinned download and verification steps at https://rcourtman.github.io/presspeech/install.html#direct-download. Do not install Homebrew just for Presspeech. After verification, unzip and move Presspeech.app to Applications, but do not follow the guide's launch instruction yet. Do not run the Homebrew command when Homebrew is unavailable.

Before launching, read the installed app's version without opening it:
  plutil -extract CFBundleShortVersionString raw -o - /Applications/Presspeech.app/Contents/Info.plist
If it does not match the published version and launch decision you reviewed, stop; do not launch a different installed build. If an older 0.3.8 build is present, also point the user to https://rcourtman.github.io/presspeech/privacy.html#macos-0-3-8-after-use. The installation method alone does not establish which version is present at that path.

Only after the user makes an informed choice to launch the verified published version:
  open /Applications/Presspeech.app

After launch, Download Model in Setup starts the speech-model download and Set Up Later defers it; a valid cached model loads without another download. Before asking the user to enable Input Monitoring, explain that macOS's grant can expose typed keys; Presspeech requests keyboard events only to detect the configured hotkey and Escape to cancel an active recording, passes other keys through without saving, logging, or sending their values, and does not inspect mouse or trackpad events. Offer Apple's guide at https://support.apple.com/guide/mac-help/mchl4cedafb6/mac. Use Setup Checklist to finish the model, permissions, and hotkey readiness. The default dictation key is Right Option. Focus on setup and the first in-app test; explain that the scratchpad can still use the system clipboard and use only harmless words. Do not ask the user to star, review, or otherwise endorse the project.

A successful Try Dictation scratchpad test proves only the in-app path, not automatic paste into another app. Do not use a production field, live chat, form that can submit, or command shell as a first target. If the user asks to try another app, follow https://rcourtman.github.io/presspeech/getting-started.html#first-app with harmless words in a blank, disposable field. Count an automatic-paste pass only when the complete text appears once with no recovery notice. On macOS, a copied notice is manual recovery, not a paste pass: inspect the intended field first, then verify the clipboard still holds the complete transcript before manual paste; a later copy may have replaced it. Do not retry blindly. Use https://rcourtman.github.io/presspeech/app-compatibility.html before relying on repeated delivery to a specific app.

Only if the user asks about a future build: check GitHub Releases and the deployed install guide before describing its controls as available. Source changes alone do not make a new download available.
