Hi
I'm new on installing OS X on Dell Laptops. I followed all Jake Lo's Guide to install Yosemite OS X 10.10 on my E6430 A12 with i5-3320M 2.6 GHz and Intel HD4000
https://osxlatitude.com/index.php?/topic/7478-dell-latitude-yosemite-install-guide/
Everything is working according the guide above but the wifi, but that's ok since I'm using the default one.
Before I tried several other options and some components were not working, however at the end I always ended with the same problem: Screen artifacts when HD 4000 was enabled.
I uploaded a video showing these moving artifacts (sorry for the file size).
I have an external HDMI monitor 1080p working with sound and no artifacts or any problems at all.
The built-in display on the laptop is always showing these moving artifacts and lines.
I really appreciate any help please.
Thanks in advance
E6430
