How To Create MacBook Pro 13,2 From HP EliteBook 820 G3

• I’ve bought a DW1820a to replace the original Bluetooth-Wifi combo from Intel on Ebay for $22 so I can have handoff support hence Airdrop with macOS Big Sur. People seem to like DW1560 but it cost more and does the same thing.

• Now it’s time to configure the new NVME drive and install Windows 10. We need to use the created USB windows 10 installer to boot, in order to boot from external USB, we need to disable secure boot and enable legacy boot. If we’re going to use BlueStacks for Android, turn on the Virtual Technology (VTx) option in the BIOS also.

At the boot screen, we select repair instead of installation, then we get to the CMD screen to use command diskpart to configure the new NVME drive. We need to convert drive to gpt, create EFI folder and msr for windows 10 before we can install correctly.

• When the diskpart is done, we shutdown and reboot again to windows 10 installer, this time we select installation.

  NVME install

  

  Copying files

  

  Done

• When the Windows installation is done, we need to shrink a partition for macOS Big Sur, create a simple partition with ntfs for the shrunk partition and named it BigSur or anything you like.

Installing macOS Big Sur

• We need to create a 16GB flash drive that includes an EFI folder with either Clover or OpenCore or both boot loaders for our laptop and a Big Sur installer. This one is kinda of a chicken and the egg thing, you have to either download a Big Sur iso file from a website like Olarila.com.  Follow the instructions on this post to create the flash drive.
