Spindump on Mac: What Is It & How to Use It on MacBook?

Troubleshooting Unresponsive Mac Apps with Spindump

A frozen app can bring your Mac to a standstill. While force quitting offers immediate relief, understanding the root cause is crucial for preventing future issues. This is where Spindump comes in. This guide explains what Spindump is, how to use it, and when it's most helpful. We'll also explore alternative methods for improving Mac performance.

What is Spindump?

Spindump is a macOS debugging tool generating reports on unresponsive apps that have been force-quit. These reports are invaluable to developers and support teams for diagnosing performance problems like freezing, crashing, and excessive fan noise. You can generate Spindump files within Activity Monitor, the same tool used to manage resource-intensive processes.

Spindump's Function

Spindump analyzes macOS data to pinpoint app-related problems. While the technical detail might overwhelm average users, it's a lifesaver for troubleshooting teams and developers. Note that resource-intensive processes, like WindowServer, can also be managed in Activity Monitor.

CPU Resource Usage

Spindump can consume significant CPU resources, especially when dealing with a hung or crashed app. This is because it's generating a detailed report. High CPU usage can also occur when your Mac detects performance bottlenecks or is generating logs via Activity Monitor or Terminal. If specific apps consistently cause problems, consider uninstalling unnecessary applications or default Mac apps to free up memory and improve performance.

Creating a Spindump Report

To create a Spindump report:

1. Open Activity Monitor (Finder > Applications > Utilities > Activity Monitor).
2. Select the problematic app.
3. Choose View > Run Spindump from the menu bar.

When to Use Spindump

Use Spindump when apps frequently freeze, crash, or cause significant spikes in CPU or memory usage.

Alternative: MacKeeper's Memory Cleaner

For a more user-friendly approach to memory management, consider using a third-party tool like MacKeeper's Memory Cleaner. This tool provides a clear overview of memory usage and allows you to easily free up RAM.

Disabling Spindump

To disable Spindump (advanced users only):

1. Restart your Mac, pressing Command R for Recovery Mode.
2. Open Terminal and enter csrutil disable. Press Enter.
3. Reboot.
4. Open Terminal and enter sudo su launchctl unload -w /System/Library/LaunchDaemons/com.apple.spindump.plist. Press Enter. Enter your password when prompted.
5. Enter the following commands on separate lines, pressing Enter after each:
   • mount -uw /*
   • killall Finder
   • cd /System/Library/LaunchDaemons
   • mv com.apple.spindump.plist com.apple.spindump.plist.bak
6. Exit Terminal.
7. Repeat steps 1-3, but use csrutil enable to re-enable System Integrity Protection (SIP).
8. Reboot.

Conclusion

Spindump is a powerful diagnostic tool for advanced troubleshooting. However, for everyday users, focusing on managing resource-intensive processes and utilizing memory cleaning utilities like MacKeeper's Memory Cleaner might be a more efficient and user-friendly solution for maintaining optimal Mac performance.
