  1. Hi , we have created a boot stick with help of this manual, thanks, Status now is laptop os booting and once the apple sign in shown we have no backlight , we managed with good eyes and flashlight and a HDMI connection to a connected monitor ( dragging screen form laptop to external screen), to configure the install of High Sierra, the installation itself was very fast ( about 5 minutes ) Afterwards when we choose the clover option boot form disk ,the laptop is booting but screen turns black and difficult to see is a apple logo and that's it. Need help in this. EFI.zip
  2. Hi Jake lo first thank you for this. I have a question for you if you must choose between de m4800 or 7510 laptop both with amd firepro video card. What would you choose? I have both laptops and also two topics opened on this site. Please advice So then I can focus on one of these laptop Thanks..
  3. Hi hihlla, thank you for your reply. I do not have a working clover / efi set for a Dell precision m4800. I was working on a precision 7510 with a selfmade boot stick. But that did not work very well ( our fault). Is it possible to send me your files en efi so I can test it on my m4800? I have a m4800 and a 7510 to test with, Hope to hear from you.. Thank you.
  4. We are rookies on this area so we try to read all topics and try to build a working boot stick en hopefully a working system on our laptop with the info we find on this site and other hackingtosh sites.
  5. Sorry. this is the version we created and used with my tees Dell Precision 7510 laptop. EFI.zip
  6. Hi, I got my hands on a Dell Precision 7510 ( the successor of the M4800 ) and trying to install High Sierra on it , and if this works good is my ultimate goal try to upgrade to Mojave. Together with a friend and use of the hints and tips of this great support side we managed to create a High Sierra boot stick and were able to boot the 7510 until a certain point during the installation, and then installation stops. ( video of this process ( in verbose mode ) is included. Hardware specs are : Hardware specs are: Intel i7 6820 2,7GHZ Cpu, 16 GB DDR4 ram 2133 hertz, 2 video cards, Intel Skylake Graphics 64MB inside and AMD Firepro W5710M GDDR5. 2 GB memory, 1 SSD 256 GB. and M.2 SSD 256GB drives, 15'6 inch IPS screen 1920x1080 resolution, Intel WIFI cad 8260 ( 802.110c) Audio card Realtek ALC3235 , 4x USB 3.0 , SD card slot, HDMI output. Included also are pictures of the boot stick and verbose boot of the stick with the 7510 laptop. Our questions are: Why stops the installations process at a certain point? If we are missing files/kexts needed for the process of the creation where can we find these? Is it possible to go directly to the Mojave installation and what files we need for that? Can somewhere point us to the right direction? Thanks. Verbose_boot_and_then_it_stops.docx.zip
  7. Hi we managed to create a working usb stick with High Sierra as OS. The stick is booting and starting all the way to the screen with the install bar , ( see picture ) and goes to the end of the install bar and then stops. This is just before we see the actual install screen. Why does the laptop install stops? included picture of usb boot stick. What is the next step or what we have to do to make the installation go further and end ? Thank for the tips config.plist.zip
  8. Hi Herve update from my side , we created a high Sierra usb boot disk and boot with stick on 2 dell precision and tried to boot the laptops. The first laptop (precision 7510) boots with the installer , a boot option screen is shown , when we choose the USB Installer the laptop continues , you see a progress bar moving until 75% then it stops we see white stop sign and the installation stops. On the second laptop at home same procedure but with this one when I turned off the laptop , the laptop has a black screen while booting up the system No Dell startup screen is shown. , totally nothing while you can see on the HD led sign that the laptop is booting in Windows ( is still the OS on this laptop) Is this laptop destroyed ? I cannot go into the bios because I have no screen. An external screen is also not working. Any ideas ? Tomorrow we test further with the second precision 7510 at work. I also have a precision M4800 as volunteer
  9. Hi, thank you for this usefull information, but at this moment I am struggling with the creation of a bootstick, do you have a good manual for this? I am using high Sierra dmg for this
  10. Hi , no worries about the wireless internal card. I will disable it in the bios and use a external USB dongle with worked with all my previous other hackingtosh laptops 620. 630 and 830. My concern is the graphics card. I intent to use this laptop for video editing and if this is not possible then i have to look for another laptop which will work . My present macbook pro 2009 is getting sadly to old for editing stuff
  11. Hi all, I got my hands on a DELL Precision M4800 Specs: CPU Intel i7-4710 MQ Quad core 2,5 GHz (Haswell) with HD Graphic 4600 intern 16GB memory 1600Mhz DDR3L, 15,6 UltraSharp FHD 1920x1080 screen, 256 GB SSD , Intel wireless card ( I will not use this) AMD Firepro M5100w 2GB memory GDDR5 I want to use this laptop for video editing in replacement of my MacBook Pro 2009. is this possible with this configuration? Can someone help me out with a working guide for this laptop? Thanks,
  12. Hi Jake Lo, Thank you very much for your quick reply. Thus this mean I cannot use the AMD Firepro video card inside the laptop? That would be disappointing because this is a great video card with a lot of memory and fast memory and I want to use this laptop ( it it works ) for photo and video editing greets, rjjd

  14. Do you have an solution for the NullCPUPowermanagement error ?
  15. Hello i created as described successfully 2 usb sticks with yosemite on it. I started this morning my dell with usb connected to it. Error message MACH_KERNEL error cannot find.. Check it with my macbook and discovered mistake. I copied mach_kernel in folder library/kernels/kernel instead of library/kernel. Problem solved desktop is booting now totally up with usb stick . Installed Chameleon and done all steps in chapter 4 except step 4 6 and 7 I do not understand with is being written (sorry) steps 6 and 7 i did not do because i would try first to bot the machine on itself. But i get KP with message about this NullCPUPowerManagement .. How can i some this? i can boot normally with usb stick and then choose me HD. other small question: When desktop is booting it startup in DOS screen can this being changed in an GUI look ? Thanks,.
