Update : you can mark this as Closed and success. i made DWA 131 working by injecting the EFI that are located in pkg , the kexts that i injected initially are not compatible . thanks againe guys !

thanks @jakelo 1-i tried these out , also 13, 20, 86 , it always indicate : no audio device detected , maybe somthing's up with AppleAlc kext, should i switch to voodooHDA ? tough i downloaded it from dortania. EDIT : i fixed the audio by using VoodooHDA , and layout-id 5 , many thanks 2-also i don't know if i should post thiis here or creat a new topic for it , regarding WIFI Dongle DWA-131 , back in catalina clover all i had to do is to download a pkg and i'm good to go , with OC and big sur i have to use this : https://github.com/chris1111/Wireless-USB-OC-Big-Sur-Adapter SIP is disabled in nvram (FF0F0000) , the sofware needs the rtwlanu1827.kext rtwlanu.kext , i downloaded them on some website , when i inject them and reboot a pannic shows up , i wonder if there is rtwlanu kexts specific to OC. video tutorial : 3350 working EFI , no WIFI.zip

Update : thank to help from Hervé i could make it work , you'll find attached the working install config.plist if anybody has latitude 3350 , however i have three problems with the actual install : 1-regarding the track pad , it doesn't work and i have to use an external usb mouse instead , the keyboard is working just fine , for info i have an Alps alpine PS2 trackpad, i only find voodoo kexts which dont seem to work , i can send u a copy of a catalina working clover 2-I have the same problem i had with catalina regarding hibernation , when i clove the laptop and go arround for like 15 min and i go back and open it up againe , i only see a blank grey screen and nothing else. 3- sound doesn't work i'm actually afraid to make changes that may brake it up, re installed so many times lol thanks ! EDIT : i fixed the trackpad problem with this kext : https://github.com/1Revenger1/VoodooPS2-Alps/releases/tag/1.0 i guess i fiwed the hibernation problem with following dortania's guide ( disabling it using terminal ) 3-for the sound problem , my ALC is ALC3236 , but dortania says ALC3XXX are fake , tried the codec number that worked out for me in catalina (i found out i injected 86 ! didnt work, if u find anything thanks ! also do i inject in nvram ? or the one in UEFI / audio config.plist.zip

@Hervé i wanted to start a fresh installation since i had problems with catalina and switch to OC instead of clover ( unable to fix the blanc screen after hibernation..) 1-Yes , i'm pretty sure my sysem is in UEFI. 2-how to fix that NVRAM (i can't check if it works since i don't have catalina anymore to test dortania's command line)? although i know how to inject the msu-product-url in the config.plist, i'm going to do it right now while waiting for an answer. , or i'll try to switch to emulated NVRAM 3-if none of the above works out i think i can re install catalina since i have a working clover file if this is the only solution. EDIT : tried to inject msu product-url , changed the config.plist as dortania says (https://dortania.github.io/OpenCore-Post-Install/misc/nvram.html#enabling-emulated-nvram-with-a-nvram-plist) , the loop continues

i did replace the kext , same thing starts looping , then i reformatted the hard drive and started over , after the first reboot , i do see " install MacOs from-- " , i left it without touching anything then the loop starts againe. maybe i'm missing some SSDT ? 3350 is so weired the other laptops doesn't seem to go crazy like this every time we try something -_-" I also forgot to mention , the installer asks me to format the hard drive using the format : Mac os extended journaled , if i format it in APFS it wont let me install (asks me to upgrade or so , if u need the exact message i'll get it ) , and i have to use an external usb mouse since the trackpad isn't recognized for now . for info i downloaded big sur from the appstore in my virtualbox VM

i did , but still looping, did u meant that i should erase the hard drive and start from the begining i don't know if its the cause but , the sanity check points out that it might have a problem with the battery SMC https://opencore.slowgeek.com/?file=laptopbroadwell065V0JYBL&rs=laptopbroadwell065

thanks @jakelo , that booted up smooth ,started the install as usual , however after the first restart the pc is cought in a loop with this error : i went to secure boot i found it was disabled. i tried to reinstall with the usb same boot loop ! i can take out the hdd and reformat it with an external rack if needed.

thank you guys for the answers , it turned out that i uploaded the wrong EFI, the efI I uploaded was generated by ocgenX in my first attempt to get a working EFI. Please find attached the efi i created following the guide, i found out that my initial error was because the config.plist wasn't in the OC folder , when i fixed that , i got this panic : @Hervé : i used MacBookAir 7.2 , having a broadwell-U 15w 13" , that should be right ? 3350 EFI.zip

hello guys, I hope you're doing fine. I have actually Catalina installed and working on my Latitude 3350 using Clover (Big thanks to @Jake Lo), and i want to switch to Big Sur using OC since many says its better than Clover. So i went to dortania and followed the guide step by step (with the latest files possible) as much as i can and i created the EFI that u can find attached (EFI OC.zip) , however , when i try to boot it says it cant start the config, so nothing happens, i wonder where i did a mistake? If it may help , you can find attached the EFI that i use actually for catalina (EFI Clover.zip) For info my system's specs : CPU: Intel Core i5-5200U (Broadwell-U) Graphics: Intel HD 5500 LCD: 1366x768 Disk: Toshiba SATA-II 320GB MK3255GSX HDD Audio: Realtek ALC ??? (alcid=33) And I use external dongle. thanks in advance ! EFI OC.zip EFI CLOVER.zip

yes I turned it off using : sudo pmset -a hibernatemode 0 sudo rm /var/vm/sleepimage

tested it, Mac feels somewhat faster , but unfortunately works with the same consistancy as darkwake = 0

there is it debug_2937.zip

1- checked : no other voodoo anywhere else . 2-i can see it now , I have hack tool but I don't know how to rebuild cache , for fixing permission there is a tool in Cleanmymac /olarilla tools, I'll do it once I fix the sleep problem (I'm afraid if something goes south ) 3- doesn't work consistently ; sometimes it do sometimes not . any other option ?

Hello Jake lo, sorry I took so long to confirm the fix, I was overwhelmed by some Excel work on this Hackintosh, works great with upgrading extra 4go Ram. *for the mouse part , I went with your E7470, works I don't mind the caps bug, how ever there is no two fingers scroll. *for the audio part, I did not find the "extension" folder in my system, I googled and looked around since you first answered, couldn't find a relevant tutorial to show it up. ----so I changed the channels using clover configurator, then in audio preferences balance, I switched it to all left / all right , the quality is good but drops as soon as I switch to full volume or switch back balance in middle , I can live with that. *last but big problem I face right now as I was working with it, if I close the laptop and it goes to sleep mode and it takes me long to reopen it (example overnight) , as soon as I open the laptop again I face a black screen, however if its for a short time period , like 30minutes , as soon as I open the screen and I hit the power button the login screen shows up. ---I tried to mess with the clover configurator as shown in the capture, and for boot option I added slide=0. I didn't find any solution so I'm asking here as last resort, being sure you'll find a way out

here is attached , the required file , i'm trying VoodooPS2Controller-R6Bronxteck.kext while waiting for your answer, if things goes south i still have the bootable usb to boot in and get back the working voodoo kext from the folder kexts/Other/off Edit : it DID work , hower i have to keep pushing hard at the mousepad in order to navigate efficiently ; otherwise it would cut, left click works and right click too , scrolling works perfectly ; should i try the others one by one ? also about sound using headset , i can't hear the sound with the same quality as i used in windows. And when sleep mode is activated (when i close the screen for example , it can't get back on , the screen is gey ) MacBook.ioreg
