Telegram Desktop 2025 – Fix Screen Sharing Not Working on macOS Sonoma

If you use Telegram Desktop on macOS Sonoma and are stuck with a blank screen when you attempt to share your screen (or the feature simply doesn’t appear), you’re not alone. A number of users report this issue after updating either macOS or Telegram itself. :contentReference[oaicite:2]{index=2}

Quick summary: Most of the time the problem is due to macOS permissions or Telegram’s desktop client not being updated to account for Sonoma’s changes — not necessarily a hardware fault.

1. Check & Grant Screen Recording Permissions

macOS Sonoma has strict access rules: even if Telegram asks for permission, it may not work until you manually confirm settings.

Open System Settings → Privacy & Security → Screen Recording.
Ensure **Telegram Desktop** is listed and the toggle is ON. If it’s missing, click the “+” and add it.
Then go to Privacy & Security → Camera and Microphone and ensure Telegram has access.
After enabling, **restart your Mac** to apply changes.

Restarting is important because some permissions only take effect after reboot. :contentReference[oaicite:3]{index=3}

2. Update Telegram Desktop to the Latest Version

Telegram updates often include compatibility fixes for new macOS versions.

In Telegram Desktop: Telegram → Check for Updates (or download the latest DMG from the official website).
Check the version: open About Telegram, ensure it’s 2025 version build (e.g., 5.x or latest stable).
If still getting blank screen during sharing, try reinstalling Telegram.

A known issue (#26584) in the Telegram Desktop issue tracker says screen sharing fails even when permissions are granted. :contentReference[oaicite:4]{index=4}

3. Use the Correct Sharing Method in a Video Call or Group Chat

Screen sharing in Telegram Desktop only works during a video call or group voice/video session.

Start a voice or video chat in the group or contact.
Click the “Screen” or “Share Screen” button once the call has started.
Select the specific screen or window you wish to share.
If it remains blank, close the sharing overlay and try again after a few seconds.

4. Disable Hardware Accelerations / Compatibility Mode

Some users found that disabling hardware acceleration or switching to “Use system decoder” helped fix blank screen issues:

In Telegram Desktop: Settings → Advanced → Scrolling & Media (or similar) → disable “Use hardware acceleration”.
Restart Telegram and try screen sharing again.

While this step is more advanced, it has helped users with older Macs or those using external monitors. :contentReference[oaicite:5]{index=5}

5. Test With a Different Account or Group

Sometimes the issue is linked with the specific contact or group. Try switching:

Start a call in a different group or with another contact.
Check if you can share your screen there.
If yes, then the problem may be tied to the original chat settings.

6. Final Thoughts & Workarounds

If you have followed the steps above and still cannot share your screen, here are your options:

Use the **Telegram mobile app** temporarily for sharing until desktop support is stable.
Contact Telegram support and include logs — especially if using an M1/M2 Mac or external GPU. A community issue was filed by users. :contentReference[oaicite:6]{index=6}
Wait for the next Telegram update — these compatibility issues are often fixed within a patch cycle.

Many users reported this problem arises only after updating to macOS Sonoma, due to changes in how Apple handles screen capture permissions. Be sure to also check for any macOS system updates. :contentReference[oaicite:7]{index=7}
