Virtualization Support

Make sure that your computer’s hardware supports virtualization. If not, you will not be able to run VirtualBox properly. You can check if your computer supports virtualization by opening the Task Manager on Windows, clicking on the “Performance” tab, and checking if “Virtualization” is enabled under “CPU”.

Virtual Machine Configuration

Make sure that you have configured the virtual machine properly. Check that you have allocated enough RAM and disk space, and that the virtual machine is set up to run Mac OS X. You can also try increasing the video memory to improve the performance of the virtual machine.

Mac OS Installation File

Make sure that the Mac OS installation file is not corrupted. You can try downloading the file again from a trusted source. Also, make sure that you have selected the correct file in the virtual machine configuration.

VirtualBox Guest Additions
