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?

did you follow the guide and edit the plist file to the desire brightness level? then place the files in the location specified?

Some kexts won't load from /E/E and will need to be install to S/L/E, but the kexts I mentioned will load fine from /E/E. If you find that they are not loading, then go ahead and install them to S/L/E

You can't just drag the file, you have to compress it and attach it from "More Reply Options." There's installing package, you can manually copy these file to the right location. Note from guide. Note: My script just copies the BrightnessFix to the folder /usr/bin and brightnessFix.plist file to the folder /Library/Launchagents.

Yes, the modules folder is fine, but I don't think KernelPatcher is needed.

The DSDT by OP has nvidia disable and load HD4000, so use the DSDT. Add 'nv_disable=1 dart=0' to your org.chameleon.boot.plist so you don't have to enter it everytime. What is on your 1st HDD? Chameleon is installed on your 2nd HD that's why you have to select it from F12. Chameleon loader will have to be install to the 1st HD if you don't want to have to choose after reboot with F12. EDP is under construction to include Clover, so it's not currently working. No need to run it if you have everything tuned. What error are you seeing when it KP?

None of the kexts will work on Yosemite, but the DSDT/SSDT should be fine. Since you have Yosemite installed, what is not working? Kexts you should have in /Extra/Extensions: FakeSMC AppleIntelE1000e - for LAN ACPIBatteryManager - Battery Status VoodooPS2Controller - Mouse/Keyboard ACPIBacklight - Backlight control GenericUSBXHCI - USB 3.0 if it exists in your system NullCPUPowerManagement until you have a patched AppleIntelCPUPowerManagement

No, that's just the last version of Chameleon I was using, you could use the latest if you prefer. Yes, remove all and only use the one I sent. The others are for other models as it's describe in the guide.

You never mentioned the display resolution I asked for, but based on the screen capture it looks to be 1366x768. Your CPU is i7-3720qm not i7-3730qm, must be a typo on your part. The system specs look very much like my E6430 with Optimus Nvs5200M. You can use the boot file from here for E6x30 but replace DSDT with this attached. Not sure you're going with Chameleon or Clover, but if Chameleon, you can use my guide here. Good Luck! dsdt.aml.zip

Check the BIOS, video memory show 64mb on mine. From Windows, Dedicated Video Memory shows 64 MB and System Video Memory shows 0. To answer your questions 1 ) Yes, I'm using Legacy. According firewolf and other users, without this setting it causes garble screen. 2 ) Sounds like you have random theme setup. You can change it in Clover to your favorite theme 3 ) Verify AppleIntelBDWGraphicsFrameBuffer is in your USB Installer first. I would follow step 2.1 to mod the kext. I'm not comfortable modding the BIOS DSDT patching is step 3, but that's after you have the DVMT corrected I've only tested v3193 and working so can't tell you how 3202 is working until I have tested it

Your config looks fine. Install this to /S/L/E

Great that you're able to get a successful install. The issue with HD4600 is not with the DSDT. The issue is with the Framebuffer. Please upload the config that you're using currently that works.

nareto, when you connect your TV, does your TV show up in the Audio preferences? If it does, your HDMI audio is working and you control the volume from your TV as Bronxteck said.

Remove any voodoops2controller, ApplePS2Controller and install this This will allow 2 finger scrolling on the touchpad and middle mouse scrolling on the trackstick.

For Yosemite, you just needed to set SMBios.plist to MacBookAir 5.1 or 5.2.

What's your result from the one you found on the internet?

Please specify which version of OS X you're installing, your system's specs, and what procedure did you follow? Specs include CPU, IGPU, Display resolution, USB 2.0 or 3.0 (chipset) What files do you currently have? DSDT/SSDT/Kexts
