Ho già provato con i kexts I2C e non va. Sempre se non ho sbagliato qualcosa. 😅😅

 

Per il trackpad serve vedere Ioreg, perché potresti avere un controller non ancora ufficialmente supportato dal kext. Inoltre, come ha detto @Gengik84, serve sicuramente SSDT-XOSI ed eventuali altre patches

ho visto che hai kext doppi come smcbattery e acpibattery etc etc

prova, sostituisci tutta la cartella

per ora ti ho lasciato i driver che hai, ma anche il discorso di giorni fa dove dicevi che non avvii senza emuvariable è molto strano

non capisco questo problema grafico, di fatto non ho variato niente a riguardo

ho solo rimosso i kext duplicati per la batteria, AppleBacklightFixup.kext,NullEthernet.kext e per il wifi

quindi niente che possa migliorare o peggiorare la grafica stessa

che sia AppleBacklightFixup.kext mi sembra un po strano

in caso prova a rimetterlo

Insieme a vesa tolgo anche il fakeid?

si prova cosi vediamo la grafica come si comporta

poi rimuovi il layout dal config in Devices/audio/inject

e provalo tramite boot arg

esempio

alcid=20 oppure alcid=13

Please share your EFI folder 🙂

So the problem was the NVMe? you said that installing on Micron 2200 is not possible... I have a Samsung NVMe

When I try to drag the efi zip file I receive a message that I'm allowed to update only 48,83 Mb

This is the link. I just checked this refi folder on a USB installer and works, or at least I arrived in the Installer window. I already have Catalina installed so I did not gone further.  I'am pretty sure that will work for YOGA s740, but with SSD MICRON 2200 series replaced. It also works if Catalina is installed.

Yes Alessandro! The problem was the SSD. If you have a Samsung EVO or Samsung Pro (not Samsung Evo Plus - this will not work unless you'll update the firmware), I'm sure your installer will boot. I' posted the link, download the refi folder and copy/paste it on your usb installer refi partition, and it will work. If the fonts are to small try to change resolution in config.plist at 1920x1440.
