Moderators Jake Lo Posted October 10, 2014 Moderators Share Posted October 10, 2014 You need to replace the wiFi card if it's an Intel. See list of working/non-working from link on my signature below wireless_cards Link to comment Share on other sites More sharing options...

Moderators Jake Lo Posted October 10, 2014 Moderators Share Posted October 10, 2014 We don't support distro here, don't know what was patched or removed. If you want to rebuild, we have a fully working guide here that we support. Not sure what specs is your system since you didn't specify it but if you have a different processor and display resolution, it's easily fix.

Moderators Jake Lo Posted October 12, 2014 Moderators Share Posted October 12, 2014 Sorry, that guide might not work for you since you have a model with the discrete optimus card Nvs4200. See this guide instead. It disables the nvidia card and use the HD 3000 graphics. But if you prefer to use the nvidia card let me know. Which card is it showing on your current install?

Moderators Jake Lo Posted October 13, 2014 Moderators Share Posted October 13, 2014 Sleep/wake doesn't work with the nvidia nvs 4200m card. If you want sleep working, go with this guide https://osxlatitude.com/index.php?/topic/5943-dell-latitude-e6520-e6420-with-optimus-enabled-mavericks/ There's pros and cons for both With Nvidia: Pros: HDMI Audio/Video working Cons: No sleep / Unable to wake, screen stays black until hard reboot With HD 3000: Pros: Sleep/Wake Cons: No HDMI Video/Audio Link to comment Share on other sites More sharing options...
