flexmcmurphy Posted December 13, 2021 Share Posted December 13, 2021 Hello,Today I let a Catalina update go through and afterwards my Wifi doesn't work anymore.The version of Catalina didn't change, stayed at 10.15.7, but some security update went through.I am using Opencore.Before the update I had Opencore 0.7.0 and Catalina 10.15.7Before I ran let the Catalina update through I upgraded Opencore from 0.7.0 to 0.7.6 and also updated all the Kexts I have using the OCAT tool:AirportBrcmFixup.kextAppleALC.kextBrcmBluetoothInjector.kextBrcmFirmwareData.kextBrcmPatchRAM3.kextLilu.kextRealtekRTL8111.kextSMCBatteryManager.kextSMCDellSensors.kextSMCProcessor.kextSMCSuperIO.kextUSBPorts.kextVirtualSMC.kextVoodooPS2Controller.kextWhateverGreen.kext I then tested booting Catalina AFTER updating Opencore to 0.7.6 and updating the Kexts also (using OCAT) and it booted fine with everything working. After I let the Catalina security update go through I have macOS Catalina 10.15.7 (19H1519)BUT the Wifi card: BCM94352HMB is no longer recognised!I reverted to my original Opencore 0.7.0 EFI folder and Kexts and this updated Catalina boots and Wifi IS recognised.So basically I can boot and use Wifi in the updated Catalina but I need my older Opencore and Kexts EFI folder.Does anyone know why this is? I thought it was important to update everything in the EFI folder before trying a macOS update? Instead updating my EFI folder seems to have had the opposite effect.Cheers,Flex Link to comment Share on other sites More sharing options...
flexmcmurphy Posted December 13, 2021 Author Share Posted December 13, 2021 The Wifi is working again... I did an NVRAM reset from the Opencore bootpicker. Flex Link to comment Share on other sites More sharing options...
