Norton 360 is popular antivirus software that monitors viruses and spammers that could ruin your crucial data. It covers both devices running Windows and macOS.
It is an all-in-one security solution that offers a set of services like malware protection, secure VPN, password manager, PC Cloud Backup, etc.
However, there is an issue reported by users who are using Norton 360 software on their Macs. As such, some macOS Big Sur users running Norton 360 are having trouble opening or reinstalling the Norton app.
In detail, after upgrading to macOS Big Sur 11.5.2 and even the latest macOS 11.6, some users are unable to open the Norton application. However, this is not a new case, the same issue has also been reported in the past.
I’m running macOS Big Sur, version 11.5.2 and for some reason my Norton 360 won’t launch. I would like to know if there is a solution to this problem – Source
Cannot open the Norton app. I tried adding an extension on Safari – no joy. Norton Safe Web and Vault are functioning correctly. I tried to reinstall – no joy. Can open my subscription account only. Help me please. – Source
My Norton 360 for Mac has stopped working, won’t even load after updating Mac to iOS 11.5.2. I uninstalled and downloaded again, but Mac won’t even let me open the Norton 360 installer file. Norton 360 has been a continual pain on the Mac. Will there be an update? Is there a fix? Or do I have to use another product, or do I even need it? – Source
At the time, a user reported a compatibility issue for the Norton app after upgrading to macOS Big Sur 11.5.1. While another user complained about the error reinstalling the application on Mac.
A user tried workarounds such as adding an extension to the Safari browser or re-downloading the app, but was unable to browse it. Most of the users are still stuck in a situation where they cannot even open the app.
Meanwhile, some of the affected users have found a way out. A community forum user claims that Norton Support has responded to the issue and provided a link to the removal tool.
After following some instructions, he was then able to download and install Norton 360. This might help users who have been looking for a solution for a long time.
Additionally, in another case, Norton Remote support has come in handy in resolving the error. Support team helped overcome Norton 360 issue by running software to remove Norton completely.
Apparently the data was restored after uninstalling the app and everything is back to normal. Affected users can try these solutions mentioned above to get the app running again on devices running macOS.
However, the company has not said anything about why the app suddenly stopped working. But after examining this whole scenario in depth, the culprit seems to be the macOS software.
Apple has strong security and never compromises with user data. It may be possible that the new macOS Big Sur software update brought security enhancements that were not compatible with the Norton 360 app.
Although this whole situation remains a mystery and the question remains as to why this is happening. We will keep you posted on this as soon as a permanent solution to this issue emerges, so stay tuned.
