davidfrei7as Posted December 14, 2020 Share Posted December 14, 2020 Hello guys! I'm trying to install BS on an external hard drive but I'm stuck in the following situation: I start the installation without any problems using the EFI folder provided by Tanya, then the notebook restarts and I select the option for the disk I'm installing macOS on to continue the process, however the machine restarts again instead of loading the codes on the screen, when it starts again it loads the codes and falls into the macOS Catalina installation screen. I already have Catalina installed on my main SSD. I thank anyone who can help me. Link to comment Share on other sites More sharing options...

davidfrei7as Posted December 15, 2020 Author Share Posted December 15, 2020 I managed to solve the problem I mentioned above by formatting my disk in APFS format. I completed the installation successfully. I also solved the touchpad problem. But I was unable to activate the brightness control. So we have working: Intel Graphics UHD 620 HDMI with audio Display Port via USB-C Audio with sound control on hot keys Bluetooth Integrated Camera Integrated microphone Integrated keyboard Trackpad with gestures Ethernet All USB ports Does not work: brightness control by shortcut keys Wifi I will leave my EFI folder attached. If anyone can help me with the brightness control by the shortcut key I will be grateful. EFI.zip Link to comment Share on other sites More sharing options...
Administrators Hervé Posted December 15, 2020 Administrators Share Posted December 15, 2020 Re: brightness control, you should have it as long as you inject the SSDT-PNLF ACPI table. By default, the expected keyboard shortcuts won't work (but other key combinations will) until you add the SSDT-BRT6 ACPI table that was developed by Jake Lo as an alternative to DSDT patching (as described in my E6230 or 7490 guide for instance). You can look it up through a forum Search. Re: wireless, it all depends on the card fitted to your laptop. We've no crystall ball... Consult our R&D->Wireless section and its inventories for guidance. Link to comment Share on other sites More sharing options...
davidfrei7as Posted December 15, 2020 Author Share Posted December 15, 2020 Thanks for answering! I'll follow your tip for brightness control. About wifi, I already knew that my card is not compatible. So I asked for help with brightness control only. @hervé I just checked that I have the SSDT-PNLF and SSDT-BRT6 injected. but the hotkey does not respond. Do you have any other tips?

Moderators Jake Lo Posted December 15, 2020 Moderators Share Posted December 15, 2020 Well done on the touchpad...do you mine posting an IOReg file with IORegistryExplorer.app v2.1? Here's an updated Config file with the brightness control patch, see if it works. config.plist.zip Link to comment Share on other sites More sharing options...
davidfrei7as Posted December 15, 2020 Author Share Posted December 15, 2020 @Jake Lo It worked!!! Thanks a lot for the help! You asked me to post this IOReg file, but I don't know how to generate it. Link to comment Share on other sites More sharing options...

davidfrei7as Posted December 16, 2020 Author Share Posted December 16, 2020 @Jake Lo is this the file? ioreg.zip Link to comment Share on other sites More sharing options...
Moderators Jake Lo Posted December 16, 2020 Moderators Share Posted December 16, 2020 Yes, thanks. Looks good, just need 2 changes Disable SSDT-PNLF.aml, only need SSDT-PNLF-CFL.aml Don't rely on XhciPortLimit for USB port limit, customize your own with Hackintool.app or USBMap.kext Link to comment Share on other sites More sharing options...
