Very slow ethernet speeds

Q: What is a Hackintosh?

A non-Apple computer configured to run macOS using compatible PC hardware combined with a custom bootloader and configuration files to emulate a real Mac environment.

Q: Is building a Hackintosh legal?

Installing macOS on non-Apple hardware violates Apple’s End User License Agreement (EULA). It is generally not illegal for personal experimentation but not permitted for commercial use.

Q: What hardware is best for a Hackintosh?

The best hardware closely matches real Apple systems, with Intel CPUs (6th Gen to Core Ultra), AMD Radeon GPUs, compatible chipsets, and Intel-based Wi-Fi cards offering higher success rates.

Q: Can I build a Hackintosh with an AMD CPU?

Yes, macOS can run on AMD Ryzen CPUs using kernel patches, but Intel CPUs provide better native compatibility.

Q: What is OpenCore?

OpenCore is a modern Hackintosh bootloader that provides near-native macOS behavior and is the recommended bootloader for new installations.

Q: Is Clover still supported?

Yes, Clover is still supported but less recommended compared to OpenCore for modern systems.

Q: Which macOS versions support Hackintosh?

Hackintosh systems support macOS versions from Leopard up to recent releases, depending on hardware compatibility.

Q: Do NVIDIA graphics cards work on Hackintosh?

Only older NVIDIA GPUs work on older macOS versions; modern NVIDIA GPUs are incompatible with current macOS releases due to lack of driver support.

Q: What is an EFI folder?

The EFI folder contains the bootloader, drivers, kexts, and configuration files required to boot macOS on a Hackintosh.

Q: What are kexts?

Kexts (kernel extensions) are drivers that enable hardware functionality such as audio, Ethernet, USB, and graphics.

Hi all,

I've installed successfully Big Sur on the Gigabyte Z370 HD3 (bios 14b).
Everything works fine apart from ethernet and more specific the speed of it.

It doesn't get speeds above 100kb/sec. Of course it doesn't have to do with my router etc as I it works fine on other OS.

I tried so far the following kext (adding/removing each one each time)

1. IntelMausi
2. IntelMausiEthernet

Attached you can find my EFI folder.

Any help is very much appreciated.

delete and create again in system preferences / lan

go to library/preferences/systemconfiguration and delete content, reboot

I did the what you suggested but the problem is the same. I did some modifications to my EFI since the initial post (not related with ethernet) but just in case I'm attaching it again for a reference.

Speed doesn't go higher than 100-120kb/sec and at some point they go down to 0-10kb/sec. This problem drives me nuts....

Thanks
