Hi,

 

When using MacIASL and ACPI 5.0 i see only warnings, no errors, so you should be able to apply the patches needed for your system.

 

What bootloader are you using, and why can't you boot in to Yosemite? (What error) 

[Rafeh]

 i am using chameleon bootloader, it gives errors related to intel hd3000 graphics, can't connect to it,

which patches are needed to be applied??

Try this one: 

#Maintained by: RehabMan for: Laptop Patches
#graphics_HD3K_low.txt

#
# 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,snb-platform-id", Buffer() { 0x00, 0x00, 0x01, 0x00 },\n
        "hda-gfx", Buffer() { "onboard-1" },\n
    })\n
}\n
end;

If it does not work, boot with -v and attach a photo of the output.

Please help me fix this error, P state stepper error 18

For now replace the SMBIOS with iMac13,1, this should allow you to bypass that error.

 I fixed all issues , i am attaching the dsdt and ssdt(core i5 2.5 2520M) , if anyone needs its can download

and now works correctly with the your system?

I have found no errors, but you can still review the warnings as an example .... I have checked only the first warning.

 

2095 Warning ResourceTag Larger Than Field (Tag: 64 bits field: 32 bits)

for example:
 

Replace
 

CreateDWordField (BUF0, \ _SB.PCI0._Y0F._LEN, MSLN)

with
 

CreateQWordField (BUF0, \ _SB.PCI0._Y0F._LEN, MSLN)

and so on ....

In addition: 

 

Result is not used, possible operator timeout will be missed: 

            If (\_SB.WOL2)
            {
                If (\_SB.PCI0.LPCB.EC0.ECOK)
                {
                    Acquire (\_SB.PCI0.LPCB.EC0.MUT0, 0x0500)
                    Store (One, \_SB.PCI0.LPCB.EC0.WLAN)
                    Release (\_SB.PCI0.LPCB.EC0.MUT0)
                }
            }

To: 

            If (\_SB.WOL2)
            {
                If (\_SB.PCI0.LPCB.EC0.ECOK)
                {
                    Store (One, \_SB.PCI0.LPCB.EC0.WLAN)
                }
            }

No need to call something to drop it right after.
