thanks for share this config. all working fine in my machine that use i7-8665u and install sonoma. but i have a problem with battery drain. i test just open brave browser and browsing. in windows 1 hour reduce 10% but in macOS reduce 25-30%. i don't know why, but my fan got more extra work. and i think processor and disk too. i try to set fan to lowest rpm. it will make processor temperature increase up to 70c. when i use windows, temperature just up to 55c. maybe you have an experience this case and can help me about this. thank you

I think YogaSMC is not handling CPU Power management optimally. But I think in general, Hackintoshes always do worse when running macOS vs running WIndows. But you could try the following:

Monitor CPU behavior with Intel Power Gadget (compare CPU behavior when using YogaSMC vs. CPU Friend)

thanks for your advice. i followed that step, and still no change. i will try to disable config 1 by 1 to compare the differences
