There are a few key reasons why nvme technology is harder to use when building a hackintosh. Firstly, nvme technology is not natively supported by macOS, so you will need to use a third-party driver or kext in order to get it working. Secondly, nvme drives are usually boot drives, which means that you will need to use a custom bootloader in order to boot macOS from an nvme drive. Finally, nvme drives are usually much faster than SATA drives, so you will need to make sure that your hackintosh is configured correctly in order to get the best performance out of your nvme drive.
