Installing ML 1.8.4 in an Acer Aspire E1-751

[dpproject]

OK, let's see, my problem is that after installation, I can only boot mac ox with the USB connected and with safe mode.

Without USB, it stuck on a screen looking for a bootable drive. With USB and without safe mode, it stuck on grey screen, the famous grey screen with the grey apple.

I've try to load some kext in safe mode, and when I reboot the computer... kernel panic in the grey screen (using safe mode, there no other way to boot osx).

Also, I've try with GraphicsEnable=no, etc. but... no results.

Thanks

Boot with "-v" to diagnose... Take a photo of the resulting screen.

I will try HP ProBook, but without select any ProBook model.

Here is the image.

I've install ProBook Installer, unplug the USB and restart the laptop and... Black screen with:

boot0: GPT
boot0: TEST
boot0: TEST
boot0: TEST
boot0: GPT
boot0: TEST
boot0: TEST
boot0: error

Then, I do this (Solution 1 step 4)

Now, It load the chameleon menu, but booting normaly, stuck at grey screen with the apple.

Thanks for your help!, you're very kind.

It is probably a graphics issue, but your profile reflects a desktop, not laptop...

You probably need DSDT patches or bootloader flags (if using new Chimera) to select correct platform-id for your graphics (HD4000?). Also, patches depend on the resolution of your screen.

Images:

- Panic booting normal and save mode. no cache mode same reaults.
-Booting with -v

So... reinstall?.

Yes, graphics are HD4000 and resolution 1366x768.

Yes, graphics are HD4000 and resolution 1366x768.

If you're not sure what you did to cause the error, and therefore are unable to undo it, do a fresh install.

For HD4000 at that resolution, you should try these DSDT patches:

#   Brightness control fix
into device label PNLF remove_entry;
into scope label \_SB insert
begin
Device (PNLF)\n
{\n
	Name (_HID, EisaId ("APP0002"))\n
	Name (_CID, "backlight")\n
	Name (_UID, 0x0A)\n
	Name (_STA, 0x0B)\n
}\n
end

and...

#
# Use this patch if your laptop has the standard 1366x768 screen
#
# Use dual-link if you have 1600x900 or have upgraded
# to 1080p screen.
#

#   Inject HDMI info into GFX0/IGPU   */
into method label _DSM parent_adr 0x00020000 remove_entry;
into device name_adr 0x00020000 insert
begin
Method (_DSM, 4, NotSerialized)\n
{\n
    If (LEqual (Arg2, Zero)) { Return (Buffer() { 0x03 } ) }\n
    Return (Package()\n
    {\n
        "AAPL,ig-platform-id",\n
        Buffer() { 0x03, 0x00, 0x66, 0x01 },\n
        "hda-gfx",\n
        Buffer() { "onboard-1" },\n
    })\n
}\n
end;
