Hello, I have updated to Sierra using Hervé's Guide, many thanks for that! https://osxlatitude.com/index.php?/topic/8883-dell-latitude-e6230-with-i5-3340m-hd4000-and-1366x768-lcd-mavericksyosemiteel-capitan/?p=59096 As far as I can see everything works fine, except Wifi. I use an old imac card, which works fine under EC in the WWAN slot. Is the card supported under Sierra?
Trackpad is working, but not perfect. The system settings/trackpad is empty.
