arcaman6 Posted February 4, 2015 Share Posted February 4, 2015 Hi Guys I am installing Yosemite on an E6220 - standard configuration with HD3000 graphics and 4GB memory. Wifi card has been removed (as it is not supported). I am following this guide:- Dell Latitude Yosemite Install Guide Installation went very smoothly including post installation - Extra copied to root and kexts from Extra/Extensions/SLE installed using Kextwizzard - cache rebuild reported no errors. However on reboot laptop hangs. Attached picture shows the bootup screen - looks like it is about to start up the graphics screen. There are no kernel panics. If I boot in safe mode then bootup finishes and the laptop works very well. I have repeated the installation several times with the same result so I think I have followed the steps outlined correctly. Can anyone suggest what the issue may be? Thank's in advance arcaman6 Link to comment Share on other sites More sharing options...

arcaman6 Posted February 6, 2015 Author Share Posted February 6, 2015 Thanks Jake Now updated all the way to 10.10.2 and very pleased with the result - only one problem is that the UK keyboard does not seem to map well - will open a new ticket for this as it's a bit of thread. Your help is much appreciated. arcaman6 Link to comment Share on other sites More sharing options...
