Clevo W350stq - can't boot after install

Recommended Posts

Today, after several tries, i was able to install Mavericks using Niresh release.
The only boot flags needed to start the installer have been xpcm-free, to prevent the reboot problem, and -v.

But i can't enter the OSX. I have tried all flags and combinations i know: GraphicsEnabler=No/Yes, IGPEnabler=Yes/No, ncpi=0x2000, darkwake=0, dart=0, IntelAzulFB=11, cpus=1, and the common -v -f -x.

The boot always get stucked arround Stuck at "[iOBluetoothHCIController]...connected to the transport sucessfully".

Could you please give me some advices?
My Bios don't have the option to disable GPU or iGPU, nor the option to disable VT-d, which I think may be getting me in troubles...

I think you should tell your PC configuration, without it guessing in air wont work.

I've made a sucessfully instalation of Mavericks on my Clevo W350STQ (finally!!).

But it isn't a 100% working install...


Just some specs of the computer: i7-4700MQ, HM87, nVidia GTX 765m, 8GB DDR3, SATA 1TB


1- Graphics Problems


This computer has Intel HD4600 + nVidia GTX765m. First I have instaled without any graphics kext, because is the only way to get it to work. Without any kext loaded, the computer only detects 64Mb shared graphics memory, but HDMI video output works. Then I try to install AppleIntelHD5000.kext and AppleIntelAzulFB.kext, and the graphics become fully recognized (1024MB of memory, and QE/CI enabled). The problem is that with this kexts I have lost the HDMI video output.


Could anyone explaine to me how can I put HDMI back to work? This is very important for me!!!


BTW, it is possible to put the nVidia GPU working, insted of the intel one? (i know optimus is not supported)



2- CPU power managment


When I boot in verbose mode I get this message:
getCPUIDinfo: this is an unknown CPU model 0x3a
-- Power management may be incomplete or unsupported


How can I resolve this problem? How can I see if the CPU is making the stepping properly?


Now, the perfectly working stuff: sound, webcam, suspend, restart, built-in ethernet, trackpad, usb.


 Why posting in others thread ?

Hello pirikito2


I managed to install Mavericks on this PC (W230) with niresh. (standard don't install ANY graphic driver or the pc will not boot at all! also i put 'graphicsenabler=0'. 

Now I' am in mavericks but etherenet, graphics and sound won't work I tried all kext that i can find but none work. 
The ethernet is the basic RTL8167 so it's east to find kext but none of them work. 
Also getting the intel HD 4600 to work hasn't been a succes and i searched internet but couldn't find a solution.

how did you get the sound and ethernet to work ? could you post the steps/ files you used? thanks :)

Hi fleu,


To put my HD 4600 to work with QE/CI and with 1024 MB memory, i have installed 2 kexts: AppleIntelHD5000.kext (i sugest to you to install the other 2 bundles you will find available in your system for the HD5000) and also AppleIntelFramebufferAzul.kext.


Also you must put, in the chameleon plist, GraphicsEnabler=Yes, IntelAzulFB=11, SkipNvidia. Use chameleon wizard to edit your .plist with these flags.


With this kexts loaded the HD 4600 is fully recognized.


My only problem is the HDMI output wich doen't work with these kexts loaded (but works in safe boot mode, -x flag). If you find a solution for my HDMI problem, please tell me.


The ethernet is working with the Realtek 81xx included in niresh.

If you find the solution for the HDMI, please tell me ASAP.
The other problem i have identified, is the CPU speed: the CPU is always at turbo boost frequency. I have verified this with the intel utility. This happens to you too? My CPU is an intel i7-4700MQ.

    • I get this message no matter what I do, I've tried changing my SMBIOS to a newer model to no avail. Anyone no how to get the second install boot to work?
    • This is my first time doing Hackintosh. I've several other machines running Mac using UniBeast and Multi beast. I wanted to try Hackintosh Vanilla. So far, no luck. I followed the Guide and MacPwn Mojave Guide. 
    • Hello! I wanted to install MacOS High Sierra, but the SSD does not appear in Disk Manager. I have a Samsung Pro 840 250GB. Is there a Driver for Intel Gigabit 82579LM Network LAN for MacOS High Sierra?
    • This is my very first post and have looked around the forums to my question but I wasn't able to find the exact specifics that I need. This is my very first windows/mac dual boot project. I chose to attempt high sierra and I hope I am posting in the correct area. High Sierra seemed to be the newest that is possibly more stable than Mojave so I chose that. I'm reaching out to the more advanced builders and experienced people. I'm currently running Win 10 as of now and bought a separate SSD to install a macOS on. Before I invest time and energy into this. I'm wanting to get the best recommendations on what OS I should choose , if my hardware will be up for the task and my best plan of attack. I'll be honest I'm not ready to bang my head on the keyboard for hours. I've been there and done that.  My hardware was some of the best at its time in 2011 and I'm not 100% confident it will work with a more up to date macOS I'm also concerned about drivers for my GPU.  All input is welcomed   Here are my current specs:   CPU
          Intel Core i7 2600 @ 3.40GHz    28 °C
          Sandy Bridge 32nm Technology
