No "Problem Reporting" files attached.High sierra 10.13.6 wont install on my laptop. After pressing enter selecting the external flash, I cant get past the apple logo and the loading bar and circle. Ive tried to boot with safe mode and other options but all to no avail.
My specs are:
Lenovo Y-50-70 Touchscreen 1080p
Core i7-4720HQ @ 2.60GHz
Changing DVMT-prealloc to 128m is NOT optional.Hi,
firstly I want to thank you for this guide. I followed it, but couldn't change the dvmt pre allocated to 128 mb, because I have no option in my BIOS and I was afraid to flash It. I have never done something like that and found only guides where I need exactly my BIOS but no guide how to extract it or where I can download it. Lenovo just let me download an update-exe, but is this a whole BIOS?
By the way, Sierra is working on my Lenovo, the only problem is the UHD display/the Nvidia graphic card. I have glimmering on my display and many programs don't work because of a "problem withe the graphic card" in "about this mac" i can't see any graphics, but in hardware i can see my Nvidia graphics. The Web driver is installed.
i have tested so many thinks and I don't know if it is really the BIOS settings and how to fix this.
i uploaded my efi. Maybe someone knows what to do? For dummies and could explain it for dummies.
By the way, maybe you recognized that my english is not perfect, so it could be, that I have misunderstood something.

Could you help Me a little with changing the dvmt prealloc? I habe found a tutorial but I need my BIOS exe for It. I think I cannot use the Update App from Lenovo, can I?
Is there a way to extract my own BIOS?
I understood what my problem was, I was too stupid to read my bios version and searched the false version (what is no version...)You need to read/follow post #1.
