General info:
- Use Disk Utility to erase an Intel-based Mac - Apple Support
- How to download and install macOS - Apple Support
Booting Recovery (with Option-Command-R) may be a problem that far back, so you may need to use a second Mac to build a bootable installer.
When finished, you’ll have a dozen year old Mac that won’t be supported with recent apps.
If Activation Lock and a forgotten Apple Account is involved, that’s a whole ‘nother problem.
