This is great! I appreciate the effort put into creating a specific EFI folder for the Lenovo Yoga 520. It can be tricky getting a Hackintosh running smoothly, especially with compatibility issues. Having a pre-configured setup like this saves a lot of time. I bet you could even use this as a base and tailor it for other Lenovo models too! I'm curious, have you considered testing it with different configurations? Maybe even one where a certain brand of RAM, like Sprunki, would give it a boost? Thanks for sharing!
