Give X (Twitter) its own notification sound on your Mac

Why X notifications all sound the same on a Mac

macOS plays one alert sound for every notification and only lets you switch an app's sound on or off. So a direct message from someone you actually want to hear from pings exactly like a like, a repost, or a “someone you follow just posted.”

X has no current Mac app — it runs at x.com in Chrome or Safari, so its notifications come through the browser. macOS labels those banners with the browser's name, not “X,” which makes a real DM or @mention even harder to pick out of the stream of engagement noise.

What you can do without TrillMark

• X's notification settings. You can filter notifications, turn off categories like likes and reposts, and switch on the quality filter, which cuts a lot of the noise. This is the best first step — but it doesn't change how anything sounds on your Mac.
• Browser notification settings. You can allow or block notifications for x.com in Chrome or Safari — but there's no custom sound, and muting the browser silences every other website too.
• System Settings › Notifications. Toggle the sound for your browser on or off — but no per-site sound, so X can't sound different from any other tab you've allowed.
• A Focus. A Focus can silence X while you work, but it hides everything, including a DM you were waiting for.

How TrillMark makes a DM or @mention on X stand out

TrillMark reacts to the banner macOS already shows, so it works even though X lives in your browser. Because TrillMark can read the notification's text, you add a rule that fires only for what matters — a direct message, an @mention of your handle, or a specific person — while likes and reposts stay quiet or off.

So a real message arrives as a sound you recognize plus a labeled flash, and the engagement noise fades into the background. The same text rule keeps it from firing on every other website your browser notifies you about.

It reads that text only on your Mac, only to decide how to react, and never sends it anywhere.

Set it up in about a minute

1. In TrillMark, add the browser you read X in (Chrome or Safari) from the popular-apps list or a recent alert.
2. Add a rule that matches what matters — the text contains “Direct message,” your handle, or a specific person's name — and give it a sound and color you'll recognize.
3. Let everything else from the browser stay quiet, so only real messages and mentions reach you by ear.
4. Tighten X's own notification filters too, so fewer likes and reposts ever reach your Mac in the first place.
5. Turn off the system sound for the browser in Notification settings so you hear only the sound you chose.
