What is a crash?

A “crash” occurs when Vivaldi encounters an unrecoverable error and shuts down unexpectedly. Information pertaining to the crash is logged by macOS.

Crash logs are not sent back to us automatically. However, you can create a bug report and forward us a copy of the crash log manually, should you wish to assist us in resolving the issue. Such logs are greatly appreciated; they provide us with information as to exactly where in the code things went wrong.

Finding the crash logs

Crash logs can be viewed by opening the Console utility in macOS. (Console.app is located in the /Applications/Utilities folder. You can also launch it by clicking on the Launchpad icon in the Dock, open the “Others” folder, then click on the “Console” icon to open the application.)

Next, open “User Diagnostic Reports” in the sidebar to see the list of crash reports. Click on a Vivaldi crash report, then select and copy all text shown in the viewer pane.

Example of a crash log on Mac

Open TextEdit (or your favourite word processing application), paste the text from the crash report, and save it as a text file.
