Step 1: Finish necessary preparations
To ensure the smooth macOS Sequoia installation and running on VirtualBox on your PC, the following preparations are necessary.
Make sure your Windows computer meets the key requirements
- RAM (memory): at least 4GB (virtual machine is usually memory-intensive).
- Available hard disk space: at least 80GB (more free disk space enables macOS Sequoia to run smoother).
- CPU: at least 2 cores (more for better performance).
- Disable Windows "Memory Integrity" and "Windows Hyper-V" (Search for Core Isolation in the search bar and disable "Memory Integrity", open Command Prompt and enter /set hypervisorlaunchtype off, and restart Windows PC).
Free up space on your computer
Installing macOS Sequoia on your Windows computer will exhaust much storage space. If not enough space is available, the installation process will fail.
So, to promote the success of installation, remove unnecessary files on your computer to free up more space. If you think it is time-consuming to find useless files on your computer, you can use the Space analyzer feature in iBoysoft DiskGeeker for Windows to analyze the used space for quick deletion.
Back up your computer
Before starting the installation, we recommend you back up your computer to avoid data loss resulting from misoperations or accidental PC crashing. You can use iBoysoft DiskGeeker for Windows to clone your OS disk (C: drive) to make a one-to-one copy.
- Prepare a blank external drive or partition with a larger capacity than that of your OS disk.
- Download, install, and open iBoysoft DiskGeeker for Windows on your PC.
- Click "Clone OS disk" on the Clone module.
- View the source disk from the Source OS disk section.
- Hover your cursor to the Select a destination area and choose your prepared external drive as the destination disk.
- Click "Start" > Confirm on the pop-up.
- Wait for the cloning process to finish.
