What operating system are you using?

macOS

Operating System Version

macOS 26.6.1 (25G76), Apple Silicon

Reproduction steps

1. Configure a work interval longer than 99 minutes, such as 120 minutes.
2. Set showTrayIcon to true and trayIconStyle to time.
3. Start or reset the break timer.
4. Wait for the periodic tray update.

Reproduces how often: 100% by inspection: minutesRemaining() returns 120, AppIcon.trayIconFileName returns a Number120 filename, and the committed number assets only cover 0 through 99.

Expected Behavior

The macOS menu bar should show the exact remaining minutes, including three-digit values such as 120, and continue counting down without errors.

Actual Behavior

The app requests a tray image such as trayMacMonochromeNumber120Template.png, which does not exist. The resulting tray update can reach the uncaught-exception handler and quit Stretchly.

Relevant log output

No runtime failure was deliberately triggered on the active setup. Static verification showed that the number icon generator and committed assets cover only 0 through 99, while `AppIcon` accepts every non-negative integer.

Preferences

{
  "microbreakInterval": 3600000,
  "breakInterval": 1,
  "microbreak": false,
  "break": true,
  "showTrayIcon": true,
  "trayIconStyle": "time"
}

Additional information

This is narrower than #1419, which requested a more readable native macOS title, and #1369, which reports a missing negative-number icon after unlock. Neither covers valid work intervals above 99 minutes requesting an asset that does not exist.

Proposed narrow fix:

• On macOS, use Electron's native Tray.setTitle() to display exact remaining minutes, so values such as 120 do not require additional generated image assets.
• Keep the existing image-based countdown on Windows and Linux, but only select number assets for values from 0 through 99; use the normal tray icon above that range.
• Clear the macOS title while paused and during a break.
• Add regression tests for 99, 100, and 120 minutes.

I saw the maintainer's earlier comment in #1419 that a macOS-only implementation was not preferred. Would Tray.setTitle() be acceptable now as a platform-specific fix for exact three-digit values, with the guarded fallback on other platforms?

Related issues: #1194, #1369, #1419, #1741, and #1821.
