24. Open up Terminal (Spotlight search for it or navigate to /Applications/Utilities), type in "sudo[sPACE]" (without the quotes) and drag the correct version of the InstallerPrep shell script to the Terminal window. do not forget sudo it is what allows authorization.

what version bios are you on? also i see 2 models on dells site there is E5520 and also a E5520m. both have different bios and different cpu. the m is core 2 duo capable as where the other is sandy bridge. so the machines are not similar at all.

did you transfer your files from the usb to your HDD efi folder?

on the usb installer or on the hdd boot? if usb then try different ports if it's hdd boot make sure Sata is set to AHCI in bios.

Hi leppy nice to see you back again

if you can post a picture of the KP then that might help you.

do you have a working boot pack already? we would need one to add it to edp.

those kexts you saw listed in the kp is your issue. do further search on them.

i can see both points of views but even apple does not release all there code even though they are also bound. there are a lot of instances like that; like apple usb3 code and many many others as a point of reference. he has technically fulfilled his duty by releasing the code snippets he has already if it has not changed. which is the ps2 parts and the voodoo parts. but i also can agree that he could use a hand in furthering his kext. the only issue i see is that it only takes 2 minutes 2 fork over a git repo and call it your own which also happens quite frequently ,and they do not submit there changes to trunk either if they did then we would just be downloading from the original voodoo and not from a renamed forked branch. so either way i see faults.

the reason you need nullcpu kext is because you need to patch AppleIntelCPUPowerManagement kext for your platform and os version. i am guessing sandy bridge

if you never purchased it before you might not be able too.

depends on your boot loader for chameleon you have to add nullcpu.kext to Extra/Extensions check to see what your yosemite zone has in the Extra folder if it uses one. if you have intel wifi then you will not have wifi because it is not supported in OS X. it would have to be replaced with a compatible card. for trackpad you can try searching the forum for alps trackpad.

from what i understand you now need a real apple mac MLB and ROM in order to pass apple authentication.

that means your bios has a whitelist on wifi cards. it will only allow specific wifi cards to be used. you can check to see if hp has made a new bios that allows for other wifi cards to be used read the change logs for the bioses at hp's download section. your other option is to try the card in another slot if you have one or get a compatible card that is allowed in your bios and works in OS X.

hmm i guess they removed it for new purchases since yosemite is out you might have missed out.

i know clover has a kernel patch for haswell E cpu. graphics I'm not sure about from what i see in ark intel. that cpu does not have onboard graphics but i do see a mention of OS X maverick here http://www.amd.com/en-us/solutions/professional/partner/appleon a mac pro

you have to download the app then it will go to your applications folder and show as a purchase. if you never purchased it before but it is a free download so it will cost nothing.

sure

have you tried booting without legacy on in bios like the error states?

you have to be very sure of your install paths. especially with the boot loaders and kext installs you do not want it to install to your real mac. it is a recoverable problem but a sure pain in the ass.

have you tried in terminual using the command sudo pmset hibernatemode 0

could be an issue with usb 2 bus for the webcam and maybe BT but that could also be a firmware uploader issue. HPET also does like to hog up USB ports.
