Perfect thanks!

I guess that would be helpful... It's a BCM94322HM8L dw1510

Ok upgrade seemed to go well, however I have no wifi again after upgrade. To get it working before upgrade I had to use the TGa80211FamilyKext. It is still there so not sure what to try now?

Okay, all good now, upgrading to Big Sur now. Thanks again for all the help, i'll post my EFI in a bit in case anyone else can benefit.

Okay, some progress, I was reading HFSPlus can cause problems so i replaced it with the HFSPlusLegacy.efi and now i get to the picker, and Catalina loads up. My wifi is not working, and my mouse buttons don't work. (and the trackpad is a little glitchy.). Any ideas on those? Thanks! You must have replied as I was typing this. Just the config

Thanks Jake, same result, OC just won't come up. I should mention, i tried my old config, and it at least allows the the picker to come up, and i can select my installation, but it freezes.

No worries Herve, i appreciate the help! Jake, attached is my USBPorts.kext that i have been using with Catalina. Thanks! USBPorts.kext.zip

Thanks Herve, who knows what i was thinking. I did make the changes you suggested but still have the same issue, just a black screen. It does not get to the picker or even generate a log file.

Thanks Jake, I gave it a try, i just get a black screen, oc never comes up

I actually have them posted in this forum a while back (My OC, and Clover folders) Ill get IOReg shortly, thanks! Okay, here is IOReg, Thanks again. MacBook Pro.zip

I used the compare tool for OC config. Anything obvious i need with the new version of OC?

Well, i tried updating to newest clover, and also OC and I can't get either one to boot, the hang at the very beginning. Will keep trying as i have time. Thanks for the help

Thanks for the reply Herve, i added specs to my sig. So I changed to MBP 12,1 and now it is wanting me to upgrade to Monteray. Is there anyway to upgrade to Big Sur? I also have an older version of OC that works with this laptop, but i tried updating to the newest version and i get an error ocb load image failed, unsupported. Should i just stick with Clover or try and get OC working? Thanks again for the help, its been a while, just getting back up to speed.

Hello All, i have been running Catalina for a while now on my Toshiba. I was wanting to upgrade to Big Sur. Just wondering if this is an easy upgrade? I do have the hd4000 graphics, will that be a problem? (Using Clover at the moment). Any help would be appreciated. thanks!

Just posting my working EFI folders for my Toshiba Satellite C875-S7304 laptop. (Thanks again to Jake Lo for the help.) Just switched from Clover to Opencore and so far so good. (Both Clover and OC attached.) Hope they can save someone else some time! Clover.zip OC.zip

And there was sound!. So what did you do? Thanks again for the help much appreciated.

Thanks, tried setting count to 0. Did not notice any difference. Attached is the latest i have been trying. OPENCORE.zip

6 seems to work better in clover, i was having issues with my microphone using 7. I have added SSDT-XOSI. In clover, using hackintool i can see two sound devices (Realtek ALC269, and Intel HD4000 HDMI). With OC, so far i have never seen any devices show up under the sound tab.

Still no luck, im sure I'm messing something up. I have tried to look at as many examples as i could find, and have been going through the opencore/laptop guide. I don't even see any audio devices listed in hackintool. Any obvious issues with my config? Thanks again for the help. OC.zip

Ok thanks, ill give it a shot

Thanks Jake for the reply. In IOReg says layout id is 7. I have tried setting it to 7 in OC, but no luck yet. ( I also did not send my most current Clover config, that was on my usb installer. I must have changed it after i put on the local disk efi. In that config, both inject and layout are set to 7.)

Just out of boredom, was trying to use opencore instead of clover. I am successfully able to boot now with Opencore, but have not gotten audio to work as of yet. Attached are my OC config, and Clover config. Anything obvious i am missing in the config? Thanks! Configs.zip

I had to install windows on my Toshiba C875 for a work project. I followed a guide and was able to boot from windows or macOS from clover as desired. However, the other day, I was using windows and after updates/reboots, it only boots to windows. What is the property way to set up dual boot to prevent this? Thanks!

@mac0s Follow this thread 3558 and you should be good to go. (Read all of it)

@ndhien Follow through this thread https://osxlatitude.com/forums/topic/13148-solved-inspiron-3558-help-installing-mojave/ It has all the info you need. The main thing early on is to make sure you don't have loadapfsdriver.efi or hfsplus in the drivers folder, but rather at the root of the flash drive
