For example if the virtual disk is a Linux qemu disk format i.e. qcow2, after running qemu-img resize MyDisk.qcow2 +20G to expand the file MyDisk.qcow2 by 20 gigabytes, the following commands should be run in Mac terminal. Explained here.

diskutil repairdisk <disk#> e.g. diskutil repairdisk disk0 diskutil apfs resizeContainer <partition_id> 0 e.g. diskutil apfs resizeContainer disk0s3 0

• disk# and partition_id are both found using diskutil list
• partition_id is the id of the partition you'd want to expand into the free space of the disk containing it
