+# OpenCore bootloader
+
+macOS VMs require [OpenCore](https://github.com/acidanthera/OpenCorePkg) as a bootloader. Quickemu handles this automatically, but the implementation differs depending on when your VM was created.
+
+## Integrated OpenCore (new default)
+
+New macOS VMs use **integrated OpenCore**, where the bootloader is embedded directly in the EFI partition of `disk.qcow2`. This approach:
+
+- Creates a single disk image instead of two
+- Simplifies VM management and backups
+- Boots directly from the main disk
+
+This requires `mtools` and `gptfdisk` on your system. If these are missing, `quickget` automatically falls back to the legacy method.
+
+## Legacy OpenCore (separate disk)
+
+VMs created before this change use a separate `OpenCore.qcow2` file that chainloads macOS from the main disk. This results in two disk images:
+
+- `OpenCore.qcow2` - bootloader disk
+- `disk.qcow2` - macOS system disk
+
+**Existing VMs continue to work unchanged.** Quickemu automatically detects which method to use based on whether `OpenCore.qcow2` exists in the VM directory.
+
+## Using the legacy method for new VMs
+
+If you need the legacy two-disk setup for a new VM:
+
+1. Download `OpenCore.qcow2` from [OSX-KVM](https://github.com/kholia/OSX-KVM)
+2. Place it in your VM directory before running `quickget`
+3. `quickget` will detect the existing file and skip integrated OpenCore creation
