Marcel Vogt Posted June 6, 2018 Author Share Posted June 6, 2018 Thank you very much, the installation works fine. After the installation I already have some little issues, maybe you can help me there, too. I have no sound ( I put the kexts from LE folder to /Library/Extensions) When I boot Clover directly from the ssd the USB ports don't work, when I boot from the installation media USB 3 works correctly Wireless Lan does not work, do you think Broadcom BCM94322HM8L is an good working solution? Thanks a lot Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted June 6, 2018 Moderators Share Posted June 6, 2018 Did you copy the Clover folder from the USB to the SSD EFI partition? Repair permission and rebuild cache? Yes that should work or try DW1510, works natively. Link to comment Share on other sites More sharing options...
Marcel Vogt Posted June 6, 2018 Author Share Posted June 6, 2018 Yes i copied the drivers, kexts ans config file to the ssd. Everything thats work while im booting from stick, works on ssd boot, too -exept usb support. 4 hours ago, Jake Lo said: Repair permission and rebuild cache? I dont really know how to do that. Is there a tutorial for that? Link to comment Share on other sites More sharing options...

Marcel Vogt Posted June 8, 2018 Author Share Posted June 8, 2018 Thank you very much. My soundcard is working now. Only the line-out has no sound, just a hum. Is there a fix for it, too? Link to comment Share on other sites More sharing options...
