Resizing Guidance

For Linux Guests

  • The disk will be resized as requested.
  • You must then resize the partition from within the Linux guest using tools like gparted or parted.

For macOS Guests

  • After resizing, VirtualProg helps relocate the Recovery partition to the end of the disk.
  • You must then resize the APFS container from the macOS guest.
Steps:
  1. Boot into macOS Recovery (you may need to change the boot disk temporarily).
  2. Open Terminal and run: 
    diskutil list
    Find the APFS Container identifier.
  3. Resize it: 
    diskutil apfs resizeContainer <id> 0
  4. Boot back to macOS (and set the boot disk to Auto if needed).
