Telegram won’t open on your Mac if its downloaded folder has been corrupted with files that are interfering with the application installed on your device. You may have an error appear on your screen stating; ‘The last time you opened Telegram, it unexpectedly quit while reopening. Do you want to try to reopen its window again?’.

If you click ‘reopen’, Telegram will flash for a moment and shut down again.

If your Telegram folder is not corrupted on your Mac, you may be experiencing this error due to the following reasons;

Reason 1. Faulty Telegram update

Users have reported that Telegram won’t open on their Mac after their app was updated to the latest version.

This will occur if the files became corrupted during the download phase onto your Mac.

Reason 2. Telegram server is down

If the Telegram server is down, you will be unable to access your account. This is due to the request from your device not reaching the server, causing Telegram to not open on your Mac.

You can stay up to date with Telegram’s service status.

Reason 3. Unreliable internet connection

Telegram is an online instant messaging service, it needs to be connected to the internet to be able to operate.

If your Mac is paired to an unreliable network source, that keeps disconnecting, the Telegram app will have trouble connecting.

Note, a blocked IP address will prevent Telegram from opening on your Mac.

Reason 4. Mac browser issue

If you are accessing Telegram through Safari and not via the app, your browser may be experiencing issues.

This can stem from the browser cookies becoming too full, or you may have security settings that are prohibiting your browser from connecting to Telegram.

Are you attempting to access Telegram in a region where the app has been banned? If you are, you will need to make use of a VPN.

Step 2. Unplug and wait for around 2 minutes

Step 3. Plug it back in and re-enable your router

If you are trying to launch Telegram in a region that has been banned, you will need to activate a VPN and access the server through that network.

What is proxy server in Telegram?

Telegram supports the use of proxy servers for users to access the app in the regions where the service has been blocked.

The instant messaging service has a built-in proxy support setting that you can enable.

How to enable proxy in Telegram:

Step 1. Access Telegram

Step 2. Open Settings

Step 3. Click on ‘Data and Storage’

Step 4. Select ‘Proxy Settings’

Step 5. Choose ‘Add Proxy’

You will now be able to enter your IP, port, username and password.

If, however, you do not have your proxy details, you can make use of Telegram’s ‘Proxy Bots’. These robots will automatically supply you with login details, and choose a server best suited for you.


We hope you have now made sense of why Telegram won’t open on your Mac, and that you can launch your instant messaging service without experiencing login issues.

If you are accessing Telegram in a region that does not support the app, remember, enabling a VPN or making use of the apps proxy feature will help you gain access to the service.

However, if you are still witnessing Telegram closing down when you try and launch the app, you may need to contact them directly.
