ksandbergfl Posted July 20, 2022 Share Posted July 20, 2022 Hi there... I have a E7440 (edit: with the i7-4600U and a DW1510 wifi card). I have run Mojave and Catalina on it for almost 2 years. Now I am trying to install Big Sur 11.6.7. I have a MacBook Air, which I used to download the Big Sur 11.6.7 Full Installer, and to create the USB boot stick. I downloaded JakeLo's OpenCore EFI's, installed them on the USB stick, and made the requisite edits to the serial number, etc, as instructed. My USB stick boots fine, I select "Install Big Sur", but the process hangs with the progress bar about 50-60%. I enabled verbose mode, and it appears that the boot is sticking at the "apfs_module_start" step. I get the same error, regardless of the OpenCore version of the EFI (0.8, 0.78, 0.74, etc). My initial thought was maybe the APFS version changed in Big Sur 11.6.7.... so I downloaded the Full Installer for Big Sur 11.5.2 instead... but I'm getting the same issue... I'm not sure how to troubleshoot this... Thanks in advance. Link to comment Share on other sites More sharing options...

ksandbergfl Posted July 20, 2022 Author Share Posted July 20, 2022 It's the 0.7.8 EFI from JakeLo's "repo" here (see link). https://osxlatitude.com/applications/core/interface/file/attachment.php?id=33347&key=3c5d5a706aa5dcd3d7df34fb7b21248c I'm using this EFI "as is" except for the four (4) edits to the config.plist for MLB,ROM,SystemSerial and SystemUUID. I copied these values from what I am using with Mojave/Catalina. config.plist.zip Link to comment Share on other sites More sharing options...

ksandbergfl Posted July 20, 2022 Author Share Posted July 20, 2022 Oh ok, I didn't realize that... I have a BCM4332 (DW1510) that I bought second-hand, years ago, because it works "OOB" with Mojave... I figured if Big Sur didn't support it, it would just ignore it and boot up without it... Can I edit OpenCore to have no wifi at all? The laptop has a ethernet/RJ45 port, if that was the only network port, for the time being, that would be ok. Or does the Big Sur-via-OpenCore install require a wifi card if you use the MacbookPro11,4 model type? Link to comment Share on other sites More sharing options...
Administrators Hervé Posted July 20, 2022 Administrators Share Posted July 20, 2022 Of course you can edit the config. You must do it since it does not match your actual hardware. Link to comment Share on other sites More sharing options...
ksandbergfl Posted July 22, 2022 Author Share Posted July 22, 2022 OK, I edited the CONFIG.PLIST to remove the reference to the non-existent wireless card. I have Big Sur installed now. However, the laptop camera is not being recognized. Link to comment Share on other sites More sharing options...
