How to build an EFI for Dell Latitude E5450

This guide will help you make your ol' Dell laptop become a MacBook Air, and say goodbye Windows!

Notes: before copying the EFI into USB boot drive, make sure your have copy the Resources folder from OpenCorePkg into the EFI/OC folder. And you need a mouse to install macOS first, once you've done the installation process, head to this guide: Fixing trackpads in order to make the trackpad working.

Where to find my layout-id? AppleALC Supported Codecs.

SMBIOS	CPU Type	GPU Type	Display size
`MacBookAir7,2`	Dual Core 15W	iGPU: HD 6000	13"

This SMBIOS is suitable for our Dell, because our laptop's CPU has similar TDP compare to the MacBook Air early 2015 and Mid 2017.
