Alerter 26.4 — macOS Sequoia Compatibility Fix

Alerter 26.4 is a focused update that fixes a critical compatibility issue on macOS Sequoia. If your notifications were silently disappearing — or never showing up at all — this release is for you.

What's New

• Notifications now work out of the box on macOS Sequoia. macOS 15 silently drops notifications from unrecognized app identities. Alerter now defaults to the Terminal identity (com.apple.Terminal), which is always present on every Mac and has notification permissions. Say goodbye to silent failures and hanging processes. (#59)

• Improved reliability. A race condition between the timeout timer and dismissal polling has been fixed, preventing potential double-exit scenarios. Notification callbacks are now more robust and predictable.

• Normalized JSON output for --list. The JSON keys returned by --list are now lowercase (groupID, title, subtitle, message, deliveredAt) for consistency. Note: this is a breaking change if you were parsing the previous capitalized keys.

Upgrading

Install or update via Homebrew:

brew upgrade vjeantet/tap/alerter

Or via MacPorts:

sudo port upgrade alerter

If you were using --sender with a custom bundle ID, your setup is unaffected. The default has simply changed from fr.vjeantet.alerter to com.apple.Terminal.
