Mentis for Mac · Version 1.4.2

A little setup.
Then room to think.

Download Mentis, move it to Applications, and start writing. No account is needed.

This early release is not notarized by Apple. macOS may require your approval before it opens for the first time.

Install Mentis

Open the downloaded .dmg file.
Drag Mentis into Applications. If you already have Mentis, quit it first and replace the app in its existing location. Your writing is stored separately.
Open Mentis from Applications. You can eject the installer afterward.

If macOS blocks the first launch

Only continue if you downloaded this copy from pxsvpn.xyz and trust it. After attempting to open Mentis, go to System Settings → Privacy & Security and look for Open Anyway. macOS may ask for Touch ID or your Mac password to confirm.

Apple explains the per-app approval steps. Do not turn off your Mac’s security protections. If your work Mac is managed and approval is unavailable, contact its administrator.

Your first few minutes

Start writing immediately. In Settings, you can sign in with Google to sync your Macs and connect your own OpenAI API key for automatic names, meaning search, and suggestions. Provider usage is billed separately.

Updates fit around your work

A gold Update available button appears when a new version is ready. Open it to see what changed, then choose Install Update. You can restart immediately or keep working; the prepared update finishes when you next quit. You can also use Mentis → Check for Updates….

If you used an older version without the updater, install this release manually once. Future updates are available inside the app.

Compatibility

Requires macOS 14 or later. The universal installer contains Apple silicon and Intel builds. Installation and updating have been tested on the development Mac with Apple silicon; testing on another Mac and Intel hardware is still pending.
