jakub daniło Posted November 18, 2022 Share Posted November 18, 2022 Hello, when I try to install the system on a purchased macbook, it shows this error, there is nothing you can do except enter openshell. SSD just bought, so it's clean Quote Link to comment https://www.insanelymac.com/forum/topic/354821-error-trying-to-install-macos/ Share on other sites More sharing options...
Allan Posted November 18, 2022 Share Posted November 18, 2022 Its a Macbook with OpenCore? 🤨 Inform us the model, give us more details Quote Link to comment https://www.insanelymac.com/forum/topic/354821-error-trying-to-install-macos/#findComment-2797425 Share on other sites More sharing options...
miliuco Posted November 19, 2022 Share Posted November 19, 2022 @jakub daniło Please add a signature to your user profile. The error message seems to say that AirportBcrmFixup.kext doesn't exist in the kext folder or there is something wrong inside it. 1 Quote Link to comment https://www.insanelymac.com/forum/topic/354821-error-trying-to-install-macos/#findComment-2797487 Share on other sites More sharing options...
jakub daniło Posted December 8, 2022 Author Share Posted December 8, 2022 Sorry for the late reply but I don't have much time due to my studies MacBook 13 A1278 Intel® Core 2 DUO P8600 2.4 GHZ 4 GB RAM 240GB SSD GeForce 9400M 256MB MacOS 13 Ventura was probably installed on the MacBook, that's what the previous owner told me, he tried to fix the wifi but he failed and something like this happened Quote Link to comment https://www.insanelymac.com/forum/topic/354821-error-trying-to-install-macos/#findComment-2798462 Share on other sites More sharing options...
Slice Posted December 8, 2022 Share Posted December 8, 2022 I doubt the maOS Ventura can work on real MacBook 2013. Quote Link to comment https://www.insanelymac.com/forum/topic/354821-error-trying-to-install-macos/#findComment-2798463 Share on other sites More sharing options...
deeveedee Posted December 8, 2022 Share Posted December 8, 2022 (edited) I'm not sure I know what a MacBook 13 is (Maybe it's a MacBook 5,1?). You can check Open Core Legacy Patcher support here. If it is a MacBook5,1, OCLP claims support up to Monterey. EDIT: The OCLP guide claims that Ventura support for MacBook5,1 is in development.

Slice Posted December 9, 2022 Share Posted December 9, 2022 Core2Duo? Geforce? I am very doubt about OCLP. HighSierra is the ceiling. Quote Link to comment https://www.insanelymac.com/forum/topic/354821-error-trying-to-install-macos/#findComment-2798497 Share on other sites More sharing options...
deeveedee Posted December 9, 2022 Share Posted December 9, 2022 (edited) Yes. Yes. If P8600 is Penryn, OCLP supports it and you've seen my HackBookPro6,2, so you know that Nvidia is supported. It can't hurt to try.

deeveedee Posted December 10, 2022 Share Posted December 10, 2022 (edited) @jakub daniło I never actually looked at your first post to see the error you originally asked about. That error is typically because AirportBrcmFixup.kext is missing from the folder OC/Kexts. I ran OpenCore Legacy Patcher (OCLP) version 0.5.2 to produce the EFI for the MacBook5,1. The kexts included in the OCLP-generated EFI (listed below) do not include AirportBrcmFixup.kext. As far as I know, AirportBrcmFixup.kext is not required for a genuine Apple Mac with genuine Apple Wi-Fi card. You can read more about AirportBrcmFixup.kext here. If the previous owner of your MacBook replaced the Wi-Fi card with a non-native (not Apple) card, then AirportBrcmFixup.kext might be necessary. If your MacBook still contains the original, genuine Apple card, then AirportBrcmFixup.kext may not be necessary and you can try to disable the kext in your config.plist. EDIT: As you can see in the list of kexts below, OCLP 0.5.2 does include IO80211ElCap.kext, so it appears that newer versions of macOS require kernel patching to work with the original Apple Wi-Fi card in the MacBook5,1. After you get your MacBook booting with the current EFI (disable AirportBrcmFixup.kext in config.plist or add AirportBrcmFixup.kext to OC/Kexts), it will be interesting to know if you have working Wi-Fi. If not and you have the original Wi-Fi card, you may need to load IO80211ElCap.kext. If you feel adventurous, you may want to generate a new EFI with OCLP 0.5.2. Be sure to backup your current EFI before you replace it with a new one (just in case). Spoiler @miliuco I just noticed that you already gave this answer earlier in the thread. Sorry to be redundant!

jakub daniło Posted December 11, 2022 Author Share Posted December 11, 2022 @deeveedee Is there any way to do this without start the system?

deeveedee Posted December 11, 2022 Share Posted December 11, 2022 (edited) @jakub daniło Create a bootable USB with a new EFI generated with OCLP 0.5.2. Boot your MacBook 5,1 from the USB. EDIT: If the previous owner gave/sold you a non-bootable Mac, it's quite possible that there's more wrong with the installation than the EFI. If you don't mind starting from scratch, maybe you should recover to factory and then start from there. EDIT2: If you still have access to the previous owner, get them to help you.

deeveedee Posted December 13, 2022 Share Posted December 13, 2022 (edited) @jakub daniło You will need macOS to run Open Core Legacy Patcher. Open Core Legacy Patcher is required to create the customized EFI for your MacBook 5,1. I'm not certain, but I think that El Capitan is the latest officially supported version of macOS for your MacBook5,1. If you are installing macOS on a new SSD, you might want to install El Capitan first to make sure your laptop is working properly before you invest much time in trying to install and debug a newer, unsupported version of macOS. You can then use your MacBook running El Capitan to prepare for your upgrade. Keep in mind that the OCLP team is still working on support for Ventura. If I were trying to upgrade your laptop to a newer version of macOS, I would start by installing the latest officially supported version of macOS. EDIT: You may find a lot more support for your real MacBook5,1 by visiting the MacRumors website. There are many people at MacRumors who are upgrading their old Macs to newer, unsupported versions of macOS.
