/Extra/ssdt.aml is located on the root of your Installed OSX when you ran step 11 to generate SSDT using HVT. Reboot with your USB from step 4, and continue from step 14

See guide here. Check the updates below it for newer versions of files and patches. 1) launch dvd player, click help-> show supported features. You should see Quartz Extreme is 2) IDT 92HD93xx 3) HDMI audio enabled with patched FB, DSDT, and AppleHDA

Sorry, no new development. You can read more about it here.

Did you set bios setting for SATA Operation to AHCI?

Rebuild your cache

Do you have a patched mach_kernel for 10.9.4? If not grab it from my previous link above. Replace the one on your root. You might have to unhide it first.

You probably running Mavericks 10.9.4 with resolution 1920x1080. Same thing for my E7440 with HD4400. See here. Fix: Go to display profile and change it to sRGB.

there's a guide already for this model here. Did you have everything working with your boot files?

No I haven't. Haven't touched the 9020 for awhile now. I'll try it next week and let you know what I come up with.

Yes, the trackstick works. Install voodoops2Controller.kext for synaptics.

assuming your USB is named "myHack installer 10.9.4" and your HDD is named "Mavericks" cp "/Volumes/myHack installer 10.9.4/mach_kernel" "/Volumes/Mavericks"

It should be in the root. You could try booting up with the installer, from terminal copy the kernel over to the hard disk.

Your graphics is not loading. What graphics card does it have?

Yup still around. In order for enable HDMI Audio, you'll need to patch FB, DSDT and AppleHDA. You can read more about it here to patch FB and DSDT, but you could download the patched AppleHDA here.

See here for the latest patched AppleHDA for Exx20 models. Need to add HDAEnabler to o.c.b.p

ktbos, Since you just download Mavericks Thursday, it must be 10.9.4. You'll need to change the modded mach_kernel. Get it here and place in Extra of your USB Installer.

Please list your system specs so we could help proceed. CPU? HD 3000 or nvs4200m? Resolution?

What's your system spec? Do you have Optimus Nvidia Nvs4200m? see this. Or only HD 3000? See this.

Black and White. Should be indicated on the card too. A black and a White Triangle

Try resetting your BIOS to the Default, apply, then go back and set SATA Operations to AHCI.

Manually add this to org.chameleon.boot.plist Graphics Mode 1920x1080x32 or use Chameleon Wizard

Herve had install Yosemite with Clover here. The method cooper1 use is with the latest Chameleon made possible by Chris1111

run Terminal command lspci -nn to display the vendor/device ID of your wifi card. Not all Broadcom cards are supported. Click on Wireless Card in my signature to find a list of supported/unsupported cards.

Thank you for the guide. I don't use the nvidia card anymore. Was able to disable it with DSDT and use HD 3000 graphics instead. This allows sleep and power management. If you want to try, click on E6520 on my signature below. No issue upgrading to 10.9.4 Advantage: Sleep and battery last a bit longer and not heat up Disadvantage: No HDMI video/Audio
