Your Mac keeps system logs, which can help diagnose and troubleshoot problems with macOS and your installed applications. These logs are stored as plain-text log files on your Mac’s system drive, and macOS also includes an app for viewing them.
To view your Mac system logs, launch the Console app. You can launch it with Spotlight search by pressing Command+Space, typing “Console,” and then pressing Enter. You’ll also find it at Finder > Applications > Utilities > Console.
The Console app, also known as Console.app, is like a Windows Event Viewer for Mac.
More logs are available under Reports. To see application crash and freeze logs, click either “System Reports” for system applications or “User Reports” for user applications. You’ll see a variety of logs with file extensions like .crash, .diag, and .spin. Click them to view them in the Info pane.

Error: “Operation not permitted?”
Working with your Mac’s Terminal Utility but getting the error message “Operation not permitted?” Are Terminal commands that used to work in macOS High Sierra and Sierra not working?
this error on advanced commands like super-user sudo and change ownership chown commands but also on simple commands like the list directory command ls and others. What a mess!
easy to fix–we just need to update some of your Mac’s security and protection settings!
