Title: Troubleshooting VirtualBox Freeze on macOS Catalina 10.15.7 when Starting Windows 7 x64 (Windows 10 x64) Boot
VirtualBox is a popular virtualization software that allows users to run multiple operating systems on a single physical machine. However, some users have reported issues with VirtualBox freezing during the boot process when trying to start Windows 7 x64 (or Windows 10 x64) on macOS Catalina 10.15.7. This article will cover the possible causes and solutions to this problem.
Causes of VirtualBox Freezing during Windows Boot
There are several possible reasons why VirtualBox might freeze during the boot process when starting Windows:
- Incompatible virtual hardware settings
- Insufficient system resources
- Corrupted VirtualBox installation
- Conflicts with other software
Solutions to VirtualBox Freezing during Windows Boot
Check Virtual Hardware Settings
The first step is to check the virtual hardware settings of the Windows virtual machine. Make sure that the settings are compatible with the version of Windows you are trying to run. For example, if you are trying to run Windows 7 x64, make sure that the virtual machine is configured to use a 64-bit processor and that the amount of allocated memory is sufficient.
$ VBoxManage modifyvm <vm_name> --cpus 2 --memory 4096
Free Up System Resources
Insufficient system resources can also cause VirtualBox to freeze during the boot process. Make sure that you have enough free memory and CPU resources available. You can check the system resource usage using the Activity Monitor app on macOS.
Reinstall VirtualBox
If the VirtualBox installation is corrupted, it can cause issues during the boot process. Try uninstalling and reinstalling VirtualBox to see if that resolves the issue.
$ /Library/Application\ Support/VirtualBox/LaunchDaemons/org.virtualbox.startup.plist unload
$ sudo rm -rf /Library/Application\ Support/VirtualBox/
$ sudo rm -rf ~/Library/VirtualBox/
$ sudo rm -rf /Library/PrivilegedHelperTools/org.virtualbox.startup.tool
Disable Conflicting Software
Conflicts with other software can also cause VirtualBox to freeze during the boot process. Try disabling any conflicting software, such as antivirus or firewall programs, to see if that resolves the issue.
VirtualBox freezing during the boot process when starting Windows on macOS Catalina 10.15.7 can be caused by several factors, including incompatible virtual hardware settings, insufficient system resources, corrupted VirtualBox installation, and conflicts with other software. By following the solutions outlined in this article, you can troubleshoot and resolve the issue.
