+title: Resize Disk Size on macOS
+weight: 11
+---
+
+This guide explains how to increase the disk size of a Lima VM running on macOS when you've run out of space.
+
+## Prerequisites
+1. Sufficient free disk space on your host.
+2. Using `Qemu` VM type for the lima.
+
+## Steps to Resize Lima VM Disk
+
+1. Stop the Lima VM - 
+```sh
+limactl stop <vm-name>
+```
+
+2. Locate your disk files, lima typically uses two disk files:
+- `basedisk`: The read-only base image
+- `diffdisk`: The writable disk that stores your changes (this is the one you'll resize)
+
+These files are usually located in `~/.lima/<vm-name>/` directory.
+
+3. Resize the diffdisk file using qemu-img
+```sh
+qemu-img resize ~/.lima/<vm-name>/diffdisk <new-size>
+```
+Example for 200GB:
+```
+qemu-img resize ~/.lima/<vm-name>/diffdisk 200G
+```
+
+> Note: You may see a warning about the raw format not being specified. This is normal and can be avoided by explicitly specifying the format:
+> `qemu-img resize -f raw ~/.lima/<vm-name>/diffdisk 200G`
+
+
+4. Start the Lima VM -
+```
+limactl start <vm-name>
+```
+The filesystem will be automatically resized by  `systemd-growfs` on boot, you will see something like below:
+
+```sh
+systemd-growfs[441]: Successfully resized "/" to 199.8G bytes
+```
+
+> Note: You can verify the new size via `df -h /`.
