Signed and notarized by Apple
Casement 1.8.0 is signed with a Developer ID certificate and notarized, so a normal double-click opens it. No right-click-to-Open, no Terminal, no “damaged and can’t be opened” dialog on a fresh download.
Release notes
Casement 1.8.0
Stable · 2026-08-14 · Apple Silicon (arm64)
This is the release where Casement becomes a properly signed Mac app — and the release where Intel support ends. Read the Apple Silicon note below before upgrading.
Apple Silicon only from 1.8.0
Casement now ships one build, compiled for arm64. If your Mac has an Apple M1 chip or newer, nothing changes — update as usual. If › About This Mac reports an Intel processor, 1.8.0 will not run and the updater will not offer it; your installation stays on 1.7.1 and keeps working, but it will not receive further releases.
What changed
Apple Silicon only
From 1.8.0 onward Casement ships a single arm64 build for M1 and newer. Intel builds are no longer produced, and the update feed will not offer 1.8.0 to an Intel Mac — those installs stay on 1.7.1 instead of being handed a build that cannot launch.
No more panel flash on launch
Reader, Settings and the save-password prompt stayed mounted for a frame before hiding. They are hidden before the first paint now, so the window opens clean.
Stricter update verification
Each downloaded archive is checked against the pinned SHA-256 twice — right after download and again immediately before the swap — and the architecture is confirmed before anything is installed.
Upgrading from 1.7.x
- 1
Open Casement › Check for Updates. On Apple Silicon the 1.8.0 update downloads, verifies and installs itself.
- 2
Prefer a clean install? Download the signed DMG below and drag Casement into Applications, replacing the old copy.
- 3
Your vault, favorites, history and extensions live in the app’s data folder and survive the upgrade untouched.
- 4
Already stripped quarantine on an older build? Nothing to undo — the signed build simply stops asking.
Earlier releases
1.7.1stable · 2026-08-14
- Settings › Downloads lets you pick the folder Casement saves files to, reset back to the macOS Downloads folder, or open it.
- New option to ask where to save each file instead of downloading straight to the folder.
- Downloads with a name that already exists are numbered rather than overwritten, and an unavailable folder quietly falls back to Downloads.
- Downloadable builds are now hosted directly, so the buttons on this site install the real app.
1.7.0stable · 2026-08-14
- The password generator now has real rules: a length slider up to 128, per-set switches for a–z, A–Z, 0–9 and symbols, your own symbol list, characters to exclude, look-alike skipping and no-repeat mode.
- A live strength meter shows the entropy your rules actually produce.
- One click inserts a fresh password straight into the field you last used on the page — confirmation fields included — and copies it at the same time.
- Your generator rules are remembered between launches.
1.6.1stable · 2026-08-14
- Casement now checks for updates on its own — every few hours, on wake from sleep and when you come back to the window.
- A quiet prompt appears above the page when a new build is ready, with release notes and a one-click install.
- "Later" holds a non-critical update for a day; security releases stay visible until installed.
- Settings › Updates shows the Chromium version behind Casement and when it last checked.
1.6.0stable · 2026-08-14
- Sealed vault backups: export every saved login to a single file encrypted with a passphrase you choose.
- Restore on any Mac — pick a backup and Casement shows the sites and entry count before you unlock it.
- Merge or replace on restore, with a preview that shows exactly what will change before anything is written.
- CSV import from Chrome, Safari, 1Password and Bitwarden, plus a clearly-labelled plaintext CSV export.
1.5.0stable · 2026-08-14
- Casement can now update itself: verified downloads, release notes and a one-click install.
- Updates are checked every six hours, downloaded in the background and pinned to a SHA-256 checksum.
- New Updates pane in Settings with channel, auto-check and auto-download controls.
- The previous version is kept on disk until the new build launches cleanly.
1.4.0stable · 2026-08-14
- Full settings page: privacy controls, proxy and secure DNS, per-site permissions and theme behaviour.
- Tracker blocking, third-party cookie blocking, HTTPS-only mode and Do Not Track.
- Granular clear-browsing-data, including a clear-on-quit option.
1.3.0stable · 2026-08-13
- Built-in download manager with progress, speed, ETA, pause/resume and Show in Finder.
- Downloads persist across launches and the panel opens automatically on a new transfer.
