Windows is a relatively stable and easy-to-use OS, but just like everything tech, it runs into bugs and glitches from time to time. While some errors can be wrapped up by simply restarting your PC, others might take longer to troubleshoot. 

This article discusses the 494 error, its causes, and what you can do to fix the problem. 


What causes error 494?

The 494 error generally indicates a runtime error with an app, primarily the web browser and can be triggered by anything from a corrupt browser cache to problematic drivers. 

Do remember that the error code exists on both Windows and macOS. However, it indicates different issues in both operating systems. On Windows, the error code indicates a potential driver problem or an issue with your web browser. On macOS, the error is often seen in Safari and requires a reset to be fixed.

How to fix error 494 on macOS?

If you’re on macOS, try either of these solutions. 

Restart your browser

The first thing you should do is close all the open tabs and restart your browser entirely. This should fix the problem unless some malware or virus causes the error.


Restart your PC or router

Restarting your network equipment, such as your router or PC, can help freshen things up a bit, resolving 494 error in the process.


Update Safari

Next up, check to make sure that Safari is up to date. While the browser should automatically keep itself updated, there’s a chance that the error may have caused it to drop back a few versions. If that’s the case, updating your browser can help.


Disable extensions

Disabling extensions from the Preferences menu and then enabling them again one at a time until the error pops up again is a somewhat effective way of singling out any extensions that may be causing the problem.


Reset Safari

If nothing else works, you will have to reset Safari and start from scratch. All you have to do is head to the Preferences menu and select the Reset Safari option. This will remove all the data stored in your browser and resolve your problem.
