[Guide] Lenovo Y50 (UHD or 1080p) using Clover UEFI (10.11)

Status
Not open for further replies.
Thanks again for another excellent guide Rehabman. I have successfully installed 10.11.2 onto my Lenovo Y50-70 alongside windows 10 (stock) with two minor issues:

1) HWmonitor only shows harddrive information, no cpu information can be found
2) (not sure this is a real issue) In displays setting I can see the available options under Scaled, but when I choose any options other than the default, the screen goes black and it's very difficult to bring back the normal settings (even reboot can't fix it sometimes, I tried with connecting to an external HDMI display to bring back the display once). You can also see from the attached screenshots there are a few resolutions available (by holding options key while clicking the Scaled option). But all resolutions top at 1080p, is that the expected result? I can live with having 1080p only but it would be really nice that I can make retina scaling truly working on this beast.


Notes:
a. I changed the DMVT setting by downgrading BIOS to 1.4, booting into UEFI shell and ran
setup_var 0x18C 0x4 , upgrading BIOS back to the original 2.0.1 version
b. I use EasyUEFI for dualbooting the (stock) Windows 10
c. HWMonitor Version 6.14-291-g6b4497f.1655

By design. FakeSMC sensors are not installed by default. They are not power efficient.

If you want them, install manually: https://github.com/RehabMan/OS-X-FakeSMC-kozlek/

2) (not sure this is a real issue) In displays setting I can see the available options under Scaled, but when I choose any options other than the default, the screen goes black and it's very difficult to bring back the normal settings (even reboot can't fix it sometimes, I tried with connecting to an external HDMI display to bring back the display once).

But all resolutions top at 1080p, is that the expected result? I can live with having 1080p only but it would be really nice that I can make retina scaling truly working on this beast.

Additional scale resolutions can be added with a custom display override.

I can't patch my DSDT
Every time I try i get the following error message:

Code:
iasl -vw 2095 -p build/SSDT-HACK.aml SSDT-HACK.dsl
make: iasl: No such file or directory
make: *** [build/SSDT-HACK.aml] Error 1

You forgot to run download.sh and/or install_downloads.sh.

Follow the guide exactly as written.
 
My Windows partition isn't booting up when I hit enter on it on the bootloader. When I hit enter to the windows partition, the bootloader freezes then unfreezes and does nothing.
 

Thanks RehabMan but it doesn't seem to work. The two resolutions that I want to add (available under windows 10) are:
a. 3840x2160 (00000f00 00000870)
b. 2048x1152 (00000800 00000480)

Steps I took:
1) enable HiDPI mode (both commands)

2) find out product id an vendor id as follows:

3) sudo mkdir -p /System/Library/Displays/Overrides/DisplayVendorID-4c83

4) create ~/Desktop/DisplayProductID-4852.plist, file is attached and screenshot of it opened with Xcode is here:

5) sudo cp DisplayProductID-4852.plist /System/Library/Displays/Overrides/DisplayVendorID-4c83/DisplayProductID-4852, followed by a reboot

6) Final result (same as before)

Keep in mind that in 10.11, the display overrides are in a different folder. Read the entire thread to find out where they moved to.

(I haven't written a 10.11 guide yet)

Found it in page 14, post #140 of that guide, so I copied to a new location instead

Code:
sudo cp ~/DisplayProductID-4852.plist /System/Library/Displays/Contents/Resources/Overrides/DisplayVendorID-4c83/DisplayProductID-4852

However I still can't see the new higher resolutions than 1080p. In the guide there are a few places mention about value 00000001 (which I tried as well) but I can't seem to figure out when to add. Also I can confirm (by checking config.plist) SIP is completely disabled in my 10.11.2 installation.

Don't forget that you need to add a resolution for your target resolution and one that is double (both X/Y).

Additional clues may be obtained by looking at the overrides for actual Retina Macs.
