Issues with Post Installation on Alienware 15 R3

Thanks for your reply.
I removed FakeID in config.plist/Devices/FakeID/IntelGFX in Clover but now Sierra no longer wants to start.

You probably did not patch for the pixel clock limitation. It is required for your UHD screen.

Read the FAQ.

I followed all the tutorials :

If you can't set DVMT-prealloc as required or don't wish to risk it, you can use the minStolenSize patch. The patch is already present in the relevant plists provided by this guide, but it is disabled. Read post #2 of this guide to understand how to enable patches which are disabled.

Also, once you enable the patch, you still may have panic... It is because Clover cannot patch a kext that loads outside of kernel cache, and these graphics kexts may not be in cache. To work around this problem, use an invalid ig-platform-id (0x12345678). DO NOT use a bogus FakeID, as that will defeat the purpose. Once you are able to boot with the invalid ig-platform-id, rebuild cache, then boot normally with your intended ig-platform-id.

but it does not work. I come across a black screen after loading sierra. I think I'm hurting things but I do not know what ...

Read the related UHD topic in the FAQ.

I read :

Q. Are QHD+/UHD laptop displays supported?

Requirements for QHD+/UHD displays:
- patched IOKit framework (to remove pixel clock limitations)
- DVMT-prealloc set to 96MB or 128MB in BIOS
- Haswell: ig-platform-id 0xa2e0008
- Haswell: framebuffer configuration for 0xa2e0008 patched to match DVMT-prealloc value (Broadwell determines BIOS size dynamically)
- "normal" requirements for Haswell/Broadwell systems

Refer to this post as an example: http://www.tonymacx86.com/yosemite-...novo-yoga-2-pro-hd4400-qhd-qe-ci-working.html

For patching IOKit, clear instructions for using the-darkvoid's XPS9530.sh script are in the Y50 guide: http://www.tonymacx86.com/el-capita...-y50-uhd-1080p-using-clover-uefi-10-11-a.html

and :

Patching the IOKit framework

If you have the UHD/4K display, you must defeat the IOKit framework pixel clock checks.

Fortunately, the-darkvoid has already figured out how to patch for this and has provided a nice script in his Dell XPS 9530 repo.

To use it, copy the script and execute it:
Code (Text):

cd ~/Projects/y50.git
curl -o XPS9530.sh https://raw.githubusercontent.com/the-darkvoid/XPS9530-OSX/master/XPS9530.sh
chmod +x XPS9530.sh
./XPS9530.sh --patch-pixelclock

But when I do what is written I have a black screen on verbose mode.

Read FAQ, "Problem Reporting"

Use an external monitor if needed to collect the requested files.

Read this read that read this It is such a great help !!!! read post #9 for my files.
I give up. I thought I had a little more help than to tell me to read this or that.
Have a good day.

Comment on post #9 files already in post #10.

Don't give up yet! I was planning to get the same laptop and try to put macos on it also.
side question: how well does sierra run in virtualbox?
