How to Fix Signal Desktop Notifications Not Working

If you rely on Signal Desktop to stay connected but suddenly stop getting notifications, it’s super frustrating. As someone who uses Signal every day, I’ve had my fair share of notification headaches and figured out some practical ways to fix them. In this guide, I’ll walk you through how to troubleshoot and fix Signal desktop notifications not working — with tips you won’t always find in the official docs.

Why Signal Desktop Notifications Sometimes Fail

Before diving into the fixes, it's good to understand why Signal desktop notifications might stop working. Signal is designed to prioritize privacy and security, which means it sometimes behaves differently than other chat apps. Plus, notification issues can come from a mix of settings within Signal itself, your operating system, or even browser conflicts if you’re using the web version. Here's what I've learned:

• Notification permissions might be disabled or blocked.
• Signal Desktop app might be running but muted or minimized in a way it stops sending alerts.
• Your OS notification settings might have changed after an update.
• Background processes or focus assist modes can suppress alerts.
• Signal updates sometimes reset or change notification preferences.

Step-by-Step Fixes for Signal Desktop Notifications Not Working

Let’s get your notifications back on track. Here’s a practical checklist to troubleshoot Signal desktop notifications that I’ve personally tested on both Windows and macOS.

1. Check Signal Desktop Notification Settings

1. Open the Signal Desktop app.
2. Click on your profile icon (top left) and go to Settings.
3. Select Notifications.
4. Make sure Enable desktop notifications is toggled on.
5. Check if “Show message previews” is enabled if you want to see message snippets.
6. Also, ensure that “Mute notifications” is not activated for your chats unintentionally.

Pro tip: Sometimes, toggling notification settings off and then back on resets the system and starts alerts flowing again.

2. Verify Operating System Notification Permissions

Signal Desktop depends on your OS to actually display the notifications. Here’s how to check on common systems:

Windows 10/11

1. Open Settings > System > Notifications & actions.
2. Scroll down to find Signal Desktop in the app list.
3. Make sure notifications are turned on.
4. Ensure “Show banners” and “Play a sound” are enabled if you want both visual and audio alerts.
5. Also, check if Focus assist (aka quiet mode) is off, as it blocks notifications during certain hours.

macOS

1. Open System Preferences > Notifications & Focus.
2. Find Signal in the sidebar.
3. Toggle Allow Notifications on.
4. Choose your alert style (Banners or Alerts) — Banner disappears automatically, Alerts stay until dismissed.
5. Make sure “Play sound for notifications” is checked if you want audio alerts.

On macOS, sometimes enabling “Show notifications on lock screen” helps catch missed alerts.

3. Restart Signal Desktop and Your Computer

Sounds obvious but trust me, this one works more often than you’d think. Signal Desktop can get stuck in a weird state where notifications freeze. A quick restart of the app clears this up.

1. Quit Signal Desktop completely (right-click the icon in the system tray or dock > Quit).
2. Restart the app.
3. If that doesn’t help, reboot your computer — this resets notification services at the OS level.

4. Update Signal Desktop to the Latest Version

Signal regularly patches bugs, including notification issues. I always recommend running the latest version from signal.org. Here’s how:

1. Within Signal Desktop, click your profile icon > Help > Check for updates.
2. If an update is available, install it and restart the app.
3. Alternatively, download the installer fresh from the official site and reinstall (it won’t affect your messages).

Occasionally, older versions have known notification bugs, so this step can save you a lot of frustration.

5. Check Your Internet Connection and Signal Service Status

Signal Desktop needs a stable connection to receive messages and trigger notifications. If you’re offline or Signal servers have issues, notifications won’t arrive.

• Verify your internet is working by opening a website or using another app.
• Visit status.signal.org to see if Signal’s services are down or degraded.

Sometimes, notification delays come from server-side hiccups rather than your setup.

6. Clear Signal Desktop Cache (Advanced Step)

Here’s a less obvious tip: sometimes the app’s cache gets corrupted, causing weird notification behavior. Clearing it can fix things but requires a bit of care.

WARNING: Back up your messages before trying this because it can risk losing unsynced data.

On Windows, the cache folder is usually located at:

C:\Users\[YourUser]\AppData\Roaming\Signal

On macOS:

~/Library/Application Support/Signal

You can quit Signal Desktop, delete or rename the “Cache” folder inside the app data, and then restart Signal. It will rebuild its cache and often fix stubborn glitches.
