Resize Disk of your HSVE macOS VM

This guide has a video walkthrough, please consider watching the video here: https://youtu.be/x9CokQvbFYc

Increasing Disk Size In VM Hardware Section - Proxmox Web UI

In the Hardware tab of your VM, select your disk (e.g., `virtio0`) and click 'Disk Actions' at the top.

Enter the 'amount you want to increase it by', *not the new total size*.

Example: If your current disk is '250GB' and you want '500GB total', you must type '250'.

Expanding Disk In macOS After Increasing In VM Hardware

Boot into your macOS VM, open 'Terminal', and run:

diskutil list

This will show your disks. Example: `disk0` might be '524.4GB', but the APFS container (`disk3`) is still only '255.8GB'.

Your disk numbers may be different — double check before running commands!

Repair the Disk Partition Run:

diskutil repairDisk disk0


Type 'y' when prompted.

4Resize the APFS Container Run:

diskutil apfs resizeContainer disk3 0


This expands the APFS volume to use all available space.

Verify TRIM Status Check in 'System Information → SATA/NVMe' if 'TRIM' is enabled.
If disabled, run:

sudo trimforce enable

Done! Your macOS VM should now be using the newly expanded disk space.
