Prohibited sign during install

[DaJoker]

Hello everyone,

am kinda new to all this Hackintosh thing, and id love to be part of this community.
as the title states i start the clover install with the boot arges> dart=0 nv_disable=1 npci=0x2000 cpus=1
the install bar works until around 70% then a Prohibited Sign appears and after few min system would reboot
i am building this computer from used parts that i had laying around to replace my family's old Mac Mini that is dying,
the parts are

Mobo: Asus Rampage IV Extreme
Cpu: i7 3820
Gpu: Ram: Kingstone 4x4Gb Genesis

i have tried ever guide, every fix, every USB i own, and i looked and checked my bios over 20 times just in case i missed something. still i cant seem like i found anything that works. i read a lot of posts before making this one just in case i missed anything. am starting to give up here.

ill post my -v just in case it helps you find the problem

Have you copied any extra kext to the USB ??

i did, today in fact.
i copied the NullCPUPowerManagement and the VoodooTSCSync - 4 Core
i did try the install without any kext with the same outcomes

For installation you don't need VoodooTSCSync.kext, just use cpus=1 flag.

Also i don't think that NullCPU* kext needed when using clover.

Please remove both the kexts and boot with "dart=0 cpus=1 -v". Post result. If booting stuck, then post a clear photo of the entire screen. Also post your config.plist as a file here.

when i pluged the USB back into the iMac to remove both Kexts, the EFI parrtion wouldnt appear so i decieded to try the dart=0 cpus=1 -v and this is what i got

Make sure that CsrActiveConfig is set to 0x67 on your config.plist.

<key>RtVariables</key>
    <dict>
       <key>BooterConfig</key>
       <string>0x28</string>
       <key>CsrActiveConfig</key>
       <string>0x67</string>
    </dict>

After adding above entry, try booting with OsxAptioFixDrv-64.efi & OsxAptioFix2Drv-64.efi (do not add both drivers at the same time)

If above drivers are still making same issue, then boot with attached OsxAptioFix2Drv-free2000.efi driver.

okey so i removed both kext and add the OsxAptioFix2Drv-free2000.efi driver without the OsxAptioFix2Drv-64.efi
and i have the dart=0 nv_disable=1 npci=0x2000 cpus=1 commands, i even toke a screen shot of the -v

Looks good now.

Try booting with npci=0x3000 instead of 0x2000
