When troubleshooting problems with your Mac, it’s helpful to know when the problem occurred. Knowing the date, you can try to find out what exactly happened to the system on that particular day or time range. Perhaps the problem was caused by another update of the application or the installation of a cracked application?
Perhaps something went wrong with the last update of macOS itself? You can narrow your search by checking the dates for expected updates or software installations on your Mac.
