Question: Whenever I try to use Viber on my MacBook it won’t open. So what can I do to fix Viber for Mac not working issue?

While frequently compared to Kik, Viber is a very different app which could even be considered as much more popular. Although this is the case, it wouldn’t be fair to say that Viber is a perfect app. Recently some users have been noticing that Viber won’t open on Mac. There are a few reasons for this: the app’s system files may be corrupt, there may be a bug within the app, or the issue might actually be with your computer.

Regardless of what the problem is that is causing Viber not working on your Mac, we’re going to show you some basic fixes that will effectively deal with this problem.

1. Download The Latest Viber for Mac

This is the first thing that you should do whenever you run into a problem with any type of software-related problem. Simply updating Viber will make sure that there are no problems with the app and if any known problems were patched, updating will fix them.

Step 1: Uninstall Viber by going to the file path “/Library/ApplicationSupport/ViberPC” and deleting the entire ViberPC folder.

Step 2: Go to the Viber website and redownload the most recent Mac version via clicking here.

Step 3: Once it’s downloaded, launch the installation file and follow the setup steps to have the latest Viber version installed.


It’s likely that there’s a problem with the app, however, most people activate the auto-update feature so that all of their apps are updated automatically. Therefore, if you have this feature enabled, the problem is elsewhere.

2. Deactivate The Mac Firewall

The idea of deactivating your firewall can be daunting and worrying to do. That being said, we are only going to be temporarily deactivating it to check whether or not the issue is because of your Mac blocking a Viber connection.

Step 1:Click on the Apple icon at the top-left of your display and click “System Preferences”.

Step 2: Select the “Security & Privacy” option and then click the “Firewall” tab.

Step 3: Click on “Turn Off Firewall” and wait a few seconds.

Step 4: Once it is deactivated, check if Viber will open and if it functions properly.


If this fixes it and you no longer experience Viber won’t open on Mac, re-enable the firewall and use alternative anti-virus software.

3. Upgrade The Activation Code Error

For those of you who use Viber on both their Mac and their smartphone, there could be a problem with the activation code that was used. This is relatively easy to fix and will take no more than a few minutes to deal with.

Step 1: Update Viber on your smartphone if it isn’t up to date.

Step 2: Open Viber on your Mac and when prompted to do so, enter the activation code from your smartphone into Viber on the Mac.

Step 3: If this is the issue, Viber will now be fully functional.


Most of the time only the official activation code is accepted but, in some cases, it isn’t stored properly or is simply wrong - even though it was accepted.

4. Check “info.plist.file”

If you don’t want to go through the hassle of uninstalling and reinstalling Viber until you are sure that it’s outdated, you can check the “info.plist.file” data file to see what version of Viber is installed.

Step 1: Open the folder for your Applications and locate the Viber app.

Step 2: Hold down the CTRL key on your keyboard, click on the Viber icon, and click “Show Package Contents”.

Step 3: From the folder that is shown, open the "info.plist.file" and look for the two strings entitled “CFBundleShortVersionString” and “CFBundleVersion”.

Step 4: Compare the version numbers below these strings to the ones that are on the Viber website.

If the version which is stored in this file is different to the most recent version of Viber which is available on the app’s website, go back to the first fix that we showed you and follow those steps.
