Platform-Specific Notes

macOS

• The tool will automatically detect and use the raw device path (e.g., /dev/rdisk4)
• Automatic unmounting of volumes before firmware update
• May require full disk access in System Preferences > Security & Privacy > Privacy > Full Disk Access

Windows

• Run Command Prompt or PowerShell as Administrator
• Use drive letters (e.g., E:) when selecting drives

Linux

• Ensure your user has read/write access to the device
• May need to add udev rules for persistent device permissions

Logging

Logs are saved to migupdater.log in the current directory with timestamps and different log levels.

Troubleshooting

• Permission denied errors: Make sure to run with administrator/root privileges
• Device not found: Try unplugging and replugging the device
• Update fails: Ensure the device is not in use by other applications
• macOS security prompts: Grant full disk access to your terminal app in System Preferences
