- Insufficient System Resources: Lack of RAM or CPU allocation can lead to performance issues.
- Outdated Software: Running outdated versions of Parallels Desktop or Parallels Tools may create compatibility problems.
- Cache Issues: Corrupted cache files may impact application performance.
- High Workload: Running multiple applications simultaneously or resource-intensive tasks might cause the application to freeze.
Step-by-Step Troubleshooting Guide
Here’s a structured approach to troubleshoot and fix the issue of Parallels Desktop not responding:
Step 1: Restart Systems
- Action: Restart both macOS and Parallels Desktop.
- Reason: This will refresh the system and clear any temporary glitches.
Step 2: Check Virtual Machine State
- Action: Ensure the virtual machine is not paused or suspended.
- How: Open Parallels Desktop and look for the VM status at the top of the window.
Step 3: Verify RAM Allocation
- Action: Adjust RAM settings for your virtual machine.
- How:
- Shut down the virtual machine.
- Go to the configuration settings from the virtual machine menu.
- Adjust the RAM allocation and ensure it’s sufficient.
Step 4: Check Parallels Tools
- Action: Make sure Parallels Tools is correctly installed and updated.
- How:
- Navigate to Actions > Install Parallels Tools if the option is available.
Step 5: Repair Disk Utility
- Action: Use the Repair Disk utility to fix corrupted virtual disk files.
- How:
- Open Parallels Desktop.
- Go to the Virtual Machine menu > Manage.
- Select the option to repair.
Step 6: Clear Cache
Action: Clear the Parallels cache.
Command:
bash
rm -rf ~/.parallels-api-service/catalog_cacheReason: This can help resolve issues related to cached data.
Step 7: Reconfigure display settings
- If Black Screen Occurs:
- Change the video card settings from vmvga to vga in the Virtual Machine Configuration.
Cause / Solution Table
| Cause | Solution |
|---|---|
| Corrupted Files | Use Repair Disk utility |
