Hervé.
Thank you for the advice. I tried several times based on your advice, but Wifi and MultiTouch did not work.(But Bluetooth moved.)
[My way]
1. I installed Dr Hurt 's Voodoo PS 2 kexts using Kext Wizard. Version tried both 4 and 5. As a result, the trackpad not found error has disappeared, but it is the same as before.
2. I installed Rehabman's kexts in the same way. As a result, Bluetooth can now be used, but WiFi could not be used.
