An application log, or an application log file, is the file that records events of the application, which can reveal information about message flow issues, application problems, and user/system actions. To be more specific, the information of an application log includes: 

  • Warnings about low disk space;

  • Any significant errors;

  • An operation that has been conducted;

  • A success audit, such as a successful login;

  • A failure audit, such as a login failure.

It is totally safe to delete these application logs. Sometimes, it is necessary to delete applications logs: when you delete an application on Mac, the log files of the application are left behind taking up your space.
