How to Fix What does it take to write a kext?
This mini-guide provides a structural approach to troubleshoot and fix the issue.
Prerequisites
- Confirm your hardware specifications (CPU, GPU, Motherboard).
- Ensure you have a bootable recovery USB and backup your EFI.
Fix Steps
- Verify your network controller model (Intel, Broadcom, Realtek).
- Ensure the correct kext (e.g., AirportItlwm or BrcmPatchRAM) is loaded in your config.
- Clear network interfaces and reset NVRAM if changes don't apply.
Verification
- Reboot and verify if the functionality is restored and stable under typical usage.
Original Question:
So my laptop's wifi card isn't supported by macOS and I couldn't find any kexts for it. So I was wondering, what does it take to write one?
So the first problem would be: are there any restrictions made by macOS that wouldn't let me use my card, even with a kext?
Second, what resources do you recommend to learn this?
I know it's a hard task, but I'm up to the challenge. Even though I'll likely not going to be able to implement a driver for my wifi card, I'll probably learn a lot. I know C very well, so that's not a problem.
