Informations on creating your EFI folder and NVRam reset... :x

[t3ch]

hola.

 

i have HP and installation went all perfect because have upgrading from catalina to ventura so all partitions have been prepared, what was missing was resolution it was 1024x764... so i wanted to increase this to 1280... well there was still old EFI partition from catalina. then i downloaded SkyLake folder and removed old APPLE on EFI. i think this was big mistake to remove APPLE ??? 

 

well when i restart i showed url apple.com/osx/support or something like this.. and you are fucked up. even bios didnt work as before. for luck there still works boot menu so like this have managed all back. but i tell you bios still dont work as before. 

 

now again i will try to manage EFI partition so it can boot without usb. somehow i think someone can put little more information on how to manage these things.. ¿

hear you, love you*

-Use USB2 port for easy installation with no remap USB
-Users with IGPU can use -igfxvesa bootarg for easy installation
-Delete old EFI folder and paste new. Don't use merge files
-Don't use Drag and Drop into EFI partition. Use Copy/Paste instead
-Reset NVRAM one time - with OpenCore use entry "Reset Nvram" / with Clover use F11 key on boot screen

man this reset nvram i am scared about it..  i think it chganged all bios settings. anyway. i think on partition EFI was not installed nothing. i guess without usb wont work. normal i  use linux installation to make partitions. how will you partition your disk to run ubuntu and osx on.?

 

and are you people on any irc servers¿ maybe we can speak there because is faster..

probably with reinstalling ubuntu it will use its boot order and maybe osx will be supported there. will try.

now my disk partitions looks like this:

hey! Now works with Desktop Skylake prepared EFI and looks work all faster. great! but with resolution what should i do¿? Thanks*

 

why is missing "dict" GUI in config.plist on EFI ?

should i add this for screenresolution?

if i check config.plist UEFI -> OUTPUT -> Resolution is set to MAX.

 

and does exists any program that replace SystemSerialNumber, SystemUUID, SystemProductName that is generated with bash generate-unique-machine-values.sh -c 1 --model="iMac17,1"

? maybe i can create it if dont exists. should this work if i replace this with editor?by hand..? looks will need to try.

 

for screen resolution please help

Edited November 20, 2022 by t3ch

[t3ch]

working on modserial.py so it will read from generate-unique-machine-values.sh and search for keys/values that should be replaced. noticing and putting on git. hope you help me later.***

 

MLB i guess is board_serial right??

 

something like this:
