Changelog — Mister Plimsoll

0.6.12 (May 4, 2026)

Discrete check-interval steps. The Check every N minutes stepper now snaps between sensible values: 1, 5, 10, 15, 30, 45, 60.

Resizable Settings window. You can now drag the bottom edge to make the Settings window taller (e.g. when you have a lot of monitored volumes). Width stays fixed.

Check for Updates in the About panel. Settings > About now has a direct link next to the version, in addition to the menu bar item.
Volumes tab. Refresh moved next to the check-interval stepper, and the gap above the volumes list tightened.
Apple Account. “Apple ID” updated to “Apple Account” throughout, matching Apple’s current naming.

Fix for Messages permission. Every release from 0.6.0 onward shipped without the com.apple.security.automation.apple-events entitlement — the release script’s re-sign step was silently stripping it. macOS’s hardened runtime then blocked AppleEvents before TCC could prompt, so users got “permission needed” with no system dialog ever appearing, and Reset and try again couldn’t fix it. 0.6.9 preserves entitlements through re-sign and verifies the result before notarization.

Test-send error messages now wrap fully and stay readable instead of getting truncated mid-sentence.
When Messages.app permission is missing or stuck, the Settings panel shows an inline Reset and try again button that clears macOS's permission record and immediately re-tries the send. No more typing tccutil commands in Terminal.

Universal binary. Mister Plimsoll now ships as a true universal app (arm64 + x86_64). 0.5.0 through 0.6.6 were unintentionally Apple-Silicon-only and refused to launch on Intel Macs with a "not supported on this Mac" error. Intel Mac owners can now install and run the app.

Polished install DMG: drag-to-Applications layout with a sky-blue background, large icons, and a labeled arrow so first-time users know exactly what to do.

In-app updates via Sparkle. Mister Plimsoll now checks for updates automatically and offers to install them in place. There’s also a Check for Updates… item in the menu bar dropdown for manual checks. Future versions will arrive without you having to download the DMG by hand.
Email alerts redesigned: rich HTML with site typography (using Merriweather Sans), a single-row table with column headers, and a plain-text version for clients that prefer it. Free amount highlighted in red.
Purgeable space (APFS caches and snapshots) shown as a separate column in the email so you can tell what’s truly free vs. reclaimable.
Email footer explains how the recipient was opted in and how to disable alerts, with an inline Plimsoll-mark glyph to help locate the menu bar icon.
Contact address — misterp@misterplimsoll.app — in the About panel and footer.

Fix: Messages.app integration. Hardened-runtime entitlement was missing, which silently blocked AppleEvents to Messages and prevented macOS from prompting for Automation access. Users on 0.5.0 saw an empty Privacy & Security > Automation list and had no way to enable iMessage alerts. 0.6.0 ships the entitlement so the prompt actually appears.
Purgeable vs. truly free space. The Volume model and every display now distinguishes raw free bytes from APFS purgeable storage. You see both numbers wherever capacity appears, and totals reconcile.
Live drive list in the menu bar dropdown. Each monitored volume gets a row showing icon, percent used, mini progress bar, and the free / purgeable breakdown.
Show in Dock toggle. Optional Dock-icon presence; default off (menu bar only).
First-launch: Settings opens automatically on first run so you can pick volumes and set thresholds without hunting for the menu bar.
Cleaner alert window. Compact one-line capacity readout with the free amount in red.
Single-line schedule row in Settings, with Launch-at-login and Show-in-Dock toggles on the right.
Editable thresholds. The per-volume Alert and Max-per-day fields accept typed values as well as stepper clicks.
Animated Check Now in the menu bar: spin while checking, then a green checkmark for two seconds.
Mounted disk images (.dmg installers, sparsebundles) excluded from the monitored list so they don’t clutter Settings.

First public beta. Menu-bar utility that polls mounted volumes on a configurable interval and warns when any of them crosses a per-volume threshold.
Alert channels: on-screen banner window, email via SMTP (with credentials in macOS Keychain), and Messages.app (iMessage).
Per-volume settings: monitor toggle, threshold percentage, daily alert cap.
Time Machine destinations detected and labelled.
Launch at login (via SMAppService).
