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 https://www.insanelymac.com/forum/topic/349947-updating-catalina-breaks-my-wifi-booting-with-opencore/ 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.
