slippy_osxf Posted April 15, 2017 Author Share Posted April 15, 2017 I´ve now found a way to install sierra without errors in this guide: https://osxlatitude.com/index.php?/topic/8506-dell-latitude-inspiron-precision-clover-guide/&do=findComment&comment=54632 My problem seems to be the EFI folder or the content of it. After getting a generic EFI folder from this guide, everything works as described! Now i´ve been searching for a solution, to bring the wifi mini card "Broadcom DW1530" from Dell online. May be someone could help me in this case, too? Thanks to all for your support! And sorry for my poor english Link to comment Share on other sites More sharing options...

slippy_osxf Posted April 16, 2017 Author Share Posted April 16, 2017 @Jake Lo Do you have a recommendation for a wifi card with the best performance and compatibility for the Dell E6220? I prefer a internal wifi card. Link to comment Share on other sites More sharing options...
