Lenovo Y50 will not boot to setup

[RehabMan]

I realize that this kind of tasks are simple and basic , and it should have the basic minimum knowledge to accomplish. But as a mechanical engineer have only very basic knowledge of programming. My attempt to install mac os x is purely a hobby . However the fact that I am using this forum with the aim of I can learn and get help from more experienced people like you .

Hopes to successfully install mac os x on lenovo Y50 and then can share with the community . As I did with my old Clevos.

Anyway thank you for your time.

Sounds like you have some learning to do. Check out ACPIDebug and the README there.

Brightness fixes depend on hardware details...

Please provide complete details in your profile/signature
(Profile/Settings link in upper right corner of this site)

System: manufacturer/model + bootloader(Clover/Chameleon/Chimera)
CPU: detailed CPU model + motherboard chipset
Graphics: all graphics devices + laptop internal screen resolution

For example, typical Ivy laptop:
System: HP ProBook 4540s (Clover)
CPU: i5-3320m/HM76
Graphics: HD4000, 1366x768

Use CPU-Z on Windows to find CPU (Core iX-xxx) and motherboard chipset (HMxx), and graphics capabilities. For a laptop, these details are important and affect critical installation procedures.

Your Win81 is likely installed UEFI. Only Clover can boot it. Are you using Clover?

Haswell Brightness Fix:

You will need to extract all DSDT/SSDT from Linux. Your GFX0 device is in one of the SSDTs not DSDT and to get a proper disassembly of your DSDT (and the SSDT that has GFX0) you will need all of them. They are available in /sys/firmware/acpi/tables and /sys/firmware/acpi/tables/dynamic. Place them on USB for transfer to OS X.

It is not necessary to install Linux. Simply run it from USB: http://www.ubuntu.com/download/desktop/create-a-usb-stick-on-windows

In Linux Terminal:

# substitute DEST with the mountpoint of a FAT32 formatted USB stick
sudo cp -R /sys/firmware/acpi/tables DEST

Place all SSDT/DSDT in a single directory (rename them to *.aml as you move them) and use a recent build of iasl to disassemble:
https://bitbucket.org/RehabMan/acpica/downloads

cd "to directory where you placed all SSDT/DSDT"
iasl -da -dl *.aml

Then search the resulting *.dsl so you know where GFX0 is defined. Search for "Device (GFX0)"...

Laptop repo: https://github.com/RehabMan/Laptop-DSDT-Patch
Apply: "Rename GFX0 to IGPU" (to both DSDT and the SSDT that has your GFX0 device)
Apply: "Brightness Fix (Haswell)" to the file (SSDT or DSDT) with GFX0 device definition.
install: https://github.com/RehabMan/OS-X-ACPI-Backlight

Place patched DSDT.aml in /Extra/dsdt.aml. Place patched SSDT in /Extra/ssdt-1.aml (assuming you have already generated SSDT.aml for CPU). Obviously different locations for Clover (EFI/Clover/ACPI/patched).

Result: Working brightness slider in SysPrefs->Displays (mapping of keyboard keys is a separate issue), possible LID sleep, and IGPU power management.
