About Sysdiagnose

A sysdiagnose in macOS collects diagnostic data for troubleshooting system issues. It gathers logs, crash reports, and system state from the Mac. You can generate a sysdiagnose in a few ways, depending on the user’s access level.

​
How It Works

Sysdiagnose collects system information used to diagnose issues: performance data, logs, hardware information, and system state.

​
What Sysdiagnose Collects

When you run sysdiagnose, it gathers an extensive array of information, including:
  • System-wide performance profiles - Captures the state of running processes
  • Filesystem activity logs - Reports on system calls and page faults related to filesystem usage
  • Process information - Provides detailed data on running processes and memory usage
  • Kernel memory usage - Includes data on kernel zones and loaded kernel extensions
  • System and crash logs - Collects all relevant logs to help diagnose issues
  • Hardware and software configuration - Similar to the System Information app, but more detailed
  • Network and power management data - Details on current network status and power settings
