System log analysis to identify the cause of unintentional file deletion

Finally, I appreciate analyzing the system log and providing the useful links.

The System Logs with recent versions of macOS are completely worthless as they include so much junk and developer log entries that are not useful to an average user. Plus many of the system logs are sanitized so any potential information has been deleted for security reasons. You will just go crazy trying to examine the macOS system logs which also contain a lot of scary sounding entries that are completely harmless.

Uninstall all third party apps that are Cleaners/Optimizers/Anti-Virus/VPN

these are all know to cause issues on the macOS

These types of apps are not needed on a Mac and they usually cause more problems than they solve. Plus they impact system performance and interfere with the normal operation of macOS. These forums are full of posts where users are having severe macOS issues which are immediately resolved after properly uninstalling these types of apps by following the developer's instructions. Some of these apps are very close to being malware themselves and even formerly respected apps now are selling your personal information.

You do not need these types of apps on a Mac. Those manufacturers & developers spend lots of money marketing these useless apps by scaring users. If you see these types of apps recommended by a professional technical reviewer, then most likely that reviewer has a Windows background and is not truly familiar with macOS and is trying to get more hits for his website. macOS security is excellent already as long you as a user practices safe computing habits. The user is always the weakest link in all security measures.
