Can't boot installer (grey apple screen flashes, then reboot)

Recommended Posts

Firstly, spec.


i7-4700MQ (with integrated HD4600 gfx), 2x8GB Samsung RAM, GeForce 765M, 250GB Samsung 840 Evo disk, 750GB WD Scorpion Black disk.


Now, if I boot without any flags it flashes up the grey apple screen for a fraction of a second and then reboots.

If I just use USBBusFix=Yes if spits out a load of "EBIOS read error: Device timeout"s

If I use any other combination of flags (IGPEnabler, GraphicsEnabler, -x, -f, UseKernelCache, dart) with -v, I get to the attached image then an immediate reboot


Any help would be greatly appreciated!

    • Hello everyone,  I'm trying to install High Sierra (with AMD support) on my AMD 4500m Lenovo G505s laptop. When booting from Clover in EFI with i get some really fast screen log then the pc reboots. Now, i know there isn't a way you could help me without some info/logs, unless i'm missing a major malfunction known on these kind of laptops, so, do you know a way i could prevent it from rebooting in order to at least understand what is causing this problem? Do you think even trying to put OSX on this laptop is worth it? Thank you.
    • Hello, i am trying to install High Sierra on my ASUS X75VB but i am getting multiple errors with the ACPI.
      I believe it is CPU related?

      Mainboard: HM76 (X75VB SOCKET 0)
      CPU: Intel Core i5 3320m (Not the original CPU of this laptop!)
      GPU: Intel HD Graphics 4000 & NVIDIA 2GB Geforce 740M
      RAM: DDR3 8GB
      Storage: 120GB SSD (SATA-2)

      I have used the DSDT.aml & SSDT.aml from the following resource:

      My config.plst can be found here:

      Thanks in advance!

    • I have Yosemite Zone working on Virtualbox fine.  After downloading High Sierra Zone there is only a dmg and no ISO.  I tried converting the dmg with hdiutil but it goes to 8GB and I get "no bootable media" in Virtualbox.  Has anyone been able to do this yet?
