Do you see AppleIntelBDWGraphicsFramebuffer in the USB Installer? It's located in System/Library/Extensions Well, now that you have successfully installed it to the mSATA, check to see if AppleIntelBDWGraphicsFramebuffer is in /S/L/E. ​You don't have QE/CI because you removed ig-platform-id. If you don't have AppleIntelBDWGraphicsFramebuffer in your mSATA, see if you could copy it over from another system, must be 10.10.3.

You don't need DSDT and SSDT, but you do need org.chameleon.boot.plist and SMBios.plist. O.C.B.P tells chameleon what to load when it boots.

Yosemite, you could start reading from here. Mavericks, you can check here. If your intend is to use the Nvidia card rather than HD3000, use Wern's DSDT found in the Yosemite thread. For Clover, check this thread. There's lot of info here for this model, just use our search option.

Which OS X ?

For sound, remove whatever audio kext you currently have and install this to /S/L/E. Attached kext is for 10.9.4/10.9.5. Battery, you can't do much there, Nvidia is a battery drainer. To fix the caching issue, rebuild your permission and rebuild cache. If you're using myHack, myFix will do all of that for you.

You won't get KP with Clover loader when updating. But you'll have to repatch any files you have installed to /S/L/E AppleIntelFramebufferAzul IOGraphicsFamily

Yes, but don't forget to remove this. <dict> <key>Comment</key> <string>Boot graphics glitch, 10.10.2/10.10.3</string> <key>Find</key> <data> QYjE6xE= </data> <key>Name</key> <string>disabled:IOGraphicsFamily</string> <key>Replace</key> <data> QYjE6zE= </data> </dict>

Was your IOGraphicFamily kext vanilla? Clover patch on the fly never really work perfectly for me, some works fine, other don't. If you like, remove the Clover patch and patch the file manually and repair permission and cache. sudo perl -pi -e 's|\x41\x88\xC4\xEB\x11|\x41\x88\xC4\xEB\x31|g' /System/Library/Extensions/IOGraphicsFamily.kext/IOGraphicsFamily

You'll need to boot without cache first and reboot. See if that resolves it. Don't need the Daemon plist file. Just place voodoops2controller.kext in Clover/Kexts/10.10 or Other which ever you prefer.

Add this to KextToPatch. I also added Trim and USB 3.0 fix. Remove GenericUSBXHCI.kext and -gux_defer_USB2 boot flag Single finger side scrolling should work with VoodooPS2Controller without further configuration. If not, remove whatever PS2 controller you have and replace it with this

Your config looks fine. Are you on Yosemite 10.10.3? The kext I attached is for 10.10.3 only. Did you install with a kextwizard and repair permission and rebuild cache?

What do you have in your config file?

You need the following installed to gain QE/CI: The DSDT attached in post #333 AppleIntelFramebufferAzul attached in post #333 FakePCIID_HD4600_HD4400 FakePCIID

Explain what fix you applied... Sounds like you don't have QE/CI at all.

MacBook Pro 9.1 should work for your ivy-bridge.

That's just for wireless and work out of the box, but make sure it's DW1510 for sure. I seen other reporting they ordered DW1510 but end up with DW1520.

Location of file depends on if you're on Clover or Chameleon. For Wireless, it depends on if you only want wireless or combo wireless and bluetooth. Look at the link to see what's supported.

It's not supported. See here Unsupported: Vendor Model Format Ven-Dev id Chip Rate SL L ML Mav Yos OOB Kext (driver) Atheros AR5B125 Half Mini PCIe 168c-0032 AR9485 B/G/N N N N N N N DW1703 based on this Atheros AR5B225 Half Mini PCIe 168c-0037 AR9485 B/G/N N N N N N N -

See post #333 You'll need to replace your wifi card if it's an Intel.

Files from either should work, but seems kahuitel's might be a bit more updated. No, you will have to replace the Wifi with a supported device. Kahuitel uses an atheros but didn't mention which model. filbip mentioned a DW1510 which works out of the box, not kexts needed.

OP guide started with Lion at the time. With Mavericks, no need. MyHack has it's own version of Chameleon that will boot up to Mavericks 10.9.5, so no need to change version. Follow the installation guide to create the installer, don't format to MBR when asked, it doesn't work well. This means you'll have to find an MBR patch on the net or switch to GUID. The Maverick bootpack from my signature should be fine, it's tweaked to MBP 8.1. After creating the installer, run myHack again and select install Extra, point to the downloaded bootpack. This should get you going. Post any issue you might encounter. Yes, BIOS A13 is fine. You could find a more recent guide here for Yosemite and Mavericks by Herve.

Broadwell HD5500 is not supported until 10.10.3 which is what you are installing, so you're covered there. From the SS, it looks like it crashed where the graphics is not loading. What you'll have to do is manually patch AppleIntelBDWGraphicsFramebuffer in your installer. I have both E7250 and E7450, 1366x768 and 1920x1080 respectively. One with i5-5300u, the other i7-5600u, both booted fine with the same config and DSDT. To locate in the BIOS DVMT, go to General -> System Information, look for Video Memory. Mine shows 64 MB Note: I'm on the latest Bios A03. When you download it from Dell, there's 2 versions when you select E7250. Select E7250 and not 7250. Strange I don't know there's a Latitude 7250, couldn't find it anywhere on their site.

Note: My script just copies the BrightnessFix to the folder /usr/bin and brightnessFix.plist file to the folder /Library/Launchagents. Since you did the plist part, you still need to copy the binary to /usr/bin

What's your display resolution?
