OCLP 2.0.0 - macOS Sonoma 14 - Lenovo Z50-70 Type 80E7

Most things are just the same as Ventura-EFI except you'll need a difference SMBIOS and Sonoma specific kexts if avaliable.

Keep in mind macOS 14 Sonoma is NOT NATIVELY supported for Haswell system. this modification may cause bug glitches to an operating system.

* I am not responsible for any damage done to your device. Use at your own risk.
* Please do some research if you concerns about features included in this EFI.
* Before continuing, you are choosing to make these modifications yourself
* if any thing goes wrong, it is your responsible for the damage that happen next.

Important note

[!] Don't forget to update your kexts to Sonoma specific version if avaliable.

Every laptop are difference, even those with the same model number. So use this EFI as a reference and edit accordingly to your own hardware.

You need to generate your own SMBIOS to signin with Apple ID

Use CorpNewt's GENSMBIOS to generate platforminfo using MacBookPro15,2 as an SMBIOS for Sonoma. Head to Dortania's haswell platforminfo guide for in-depth guide.
