  1. 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

  3. Do you have an solution for the NullCPUPowermanagement error ?
  4. 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,.

I arranged an nice desktop Dell optlplex 790 SFF with Intel i7 16 GB ram and Asus GT slilent GT610 video card 2GB ddr3 ram memory and looks to me an good machine for video edting, CPU is 2 times faster an my mac pro 2008 wo i have now. Can someone tell me witch installation and extra package i must use to make this an succes? I included an CPU-Z file with the hardware components There is mentioned an standard graphic card -- i will buy and use video card described above Thanks. Dell-Optiplex-790-i7.txt
  7. Thanks all , but i think this is beyond my scope. I will startup an new project with my optiplex 790 and see how far i will come.
  8. Thanks, i will try that tomorrow but i do not have an good feeling about it. (but then it is , my mistake ) If this is not working i will proceed with the installation of the optiplex 790 and see how far i get with this machine. i tried to create an usb drive for it but no succes yet..
  9. Thanks for the replies, what is the IM download site? The second solution you mentioned was to boot the system with an bootable windows cd or usb and then execute the steps you described , but what do you mean by reformat it? And is that all what i must do.?

  12. Hi i just successful installed Lion on this laptop using an bootcd with Lion installed for this occasion. Laptop is booting up nicely with working keyboard and usb ports so i can use an usb mouse. Not working is the intel GMA 4500 MHD graphics card, Intel Gigabit cable network and audio. Wireless is no problem because i can install an usb wireless device for this. I could use some help particularly with the graphics card so if anyone could help me with this Thank you and greetz,

    Mavericks on Dell Precision 490

    Hi major break true ( also for me ) I manage to get the system up an running. First i disabled both PATA drives who were being used by two DVD - DVD writer players.. I saw that the bios settings changed and perhaps that made it possible to make the SSD data drive bootable. No problem what so ever now. I also replaced the present DSDT file installed on the desktop.. I replaced that one by another one witch i downloaded from an site ( i think insalecmac ) from an installation of ML on an Precision 690. Everything works fine now (YES) I also installed the audio kext ( voodoo) so audio also works. Leaving me only one question -- is the installation 100% succeeded? Is there away to check if everything is fully operational ? Greets..
