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

[masterscarhead1]

My guess...
I think TRIM is poorly implemented by SSD firmware.
Apple didn't code the workarounds for poor SSD firmware as it relates to TRIM.
Results with TRIM on non-Apple hardware has always been firmware/hardware dependent.

Was the code changed in HS? Because this wasn't a problem prior to HS

I have no problem with kextcache for rebuilding cache.
I don't see any documentation for kextutil that implies it can be used to rebuild kernel cache.

I apologize, I meant Kext Utility app. I should have typed it out. I had 3 cases where using kextcache led to error sign on boot
May just be a fluke, or it may mean I have too many things to be loaded (boom2.kext, and a few audio plugin stuff).
But having said that, could we delete some kexts in the extensions folder? Like the AMD kexts, or the nvidia kexts are honestly useless no? Wouldn't that speed up the boot process?

APFS is new. Did not exist for boot drives prior to High Sierra.

I apologize, I meant Kext Utility app.

I recommend avoiding that app.
It does a bunch of things it shouldn't, and things that were not requested.

You might have a mess.
So far, you have provided only incomplete "problem reporting" files.

No need to delete kexts that are not used. They are just files on disk... no impact on boot efficiency.

No sign of any unusual kexts there. Of course, signed kexts won't show... But even the last ioreg shows no sign of "Boom", but if course it also shows audio not working [kernel cache issue].

Thanks for the constant updates and work.
I have successfully upgraded my Y50 from 10.12.5 to 10.12.6 and then to 10.13, everything seems to be working correctly. (I kept my SSD partition in HFS+).

Thanks!

 

[pentium0]

OK, couple things.
First, couldn't get HS (high sierra) to boot off of USB installer, as prepared as exactly as specified, for my Y50-70 non-UHD.
What are the FULL tricks for getting HS installer USB to boot on y50-70?
I guess it doesn't matter that much if upgrade from sierra works...
Upgrade from sierra worked ...

Second, battery life estimation by istatmenu seems much better than sierra. Is that a thing?

Also, everything is working in high sierra. I have a damaged and broken non-synaptics touchpad on my y50-70, but the keyboard special FN keys still work, with the kext for non-synaptics (i forget the brand for the non-synaptics).

Also, I plan to replace the non-synaptics touchpad on my y50-70 with a synaptics, because it is physically broken.
Anyone done that? Plug and joy? I'm talking trackpad only, not whole keyboard/trackpad panel.

so... thank you tony, rehab man (group... can't be one guy)

Overview

Patching the IOKit framework

If you have the UHD/4K display, you must defeat the IOKit framework pixel clock checks.

Fortunately, the-darkvoid has already figured out how to patch for this and has provided a nice script in his Dell XPS 9530 repo.

To use it, copy the script and execute it:

cd ~/Projects/y50.git
curl -o XPS9530.sh https://raw.githubusercontent.com/the-darkvoid/XPS9530-OSX/master/XPS9530.sh
chmod +x XPS9530.sh
./XPS9530.sh --patch-pixelclock

I did all previous steps, and after everyone of them I rebooted the system, but after the IOKit patch, I am not able to boot, it starts ok, apple logo and loading bar until it gets to half of it and there is a loading circle that never stops. I tried booting from ssd and also from usb, same result.

Did you set DVMT-prealloc as required?

Hi!
I think that you need to set DVMT-prealloc to 128Mb in bios setup menu. If you need unlocked bios for your laptop, just write me.
