Malevolus Posted January 16, 2016 Share Posted January 16, 2016 Hello I am Brazilian, I hope to help me, thank you. I have a laptop Dell 5520 with i7-2620M @2.7GHz/HD3000/8Go, there is already someone with the settings I can use? how should I install Yosemite 10.10?

Administrators Hervé Posted January 16, 2016 Administrators Share Posted January 16, 2016 Your E5520 is probably not too far off the E6x20 Series, so you can use the same installation method as listed in the various guides we have on this forum for those models. You'll have to generate your own CPU-specific SSDT for CPU power management if you can't find an existing one. 1 Link to comment Share on other sites More sharing options...
Malevolus Posted January 19, 2016 Author Share Posted January 19, 2016 successfully dual boot installed. I'm using the kext voodooPS2Controller, however my touchpad does not work, only the keyboard, anyone have a solution? Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted January 19, 2016 Moderators Share Posted January 19, 2016 which bootpack did you use? where did you get your PS2 kext? Try using the version from my signature file link Exx20_touchpad. Link to comment Share on other sites More sharing options...
