Fixing Slow Internet Speeds During Hackintosh Installation (HP ProBook 440 G7)

How to Fix Slow Internet Speeds During macOS Installation

If you are installing macOS on an HP ProBook 440 G7 (Intel Core i5 Comet Lake, UHD 630) using OpenCore and experience slow internet download speeds (like 10 Mbps or less), it is likely due to incorrect Wi-Fi kexts or poor signal strength under the installer environment.

Step-by-Step Fixes

1. Use Ethernet if Possible: The recovery installer downloads the full macOS image (up to 12GB) from Apple's servers. Wi-Fi drivers in recovery are not fully optimized. Connecting a physical Ethernet cable will bypass Wi-Fi driver issues and install much faster.
2. Update Wi-Fi Kexts: If you are using an Intel wireless card, ensure you have the latest version of AirportItlwm.kext or itlwm.kext matched to your target macOS version. Placing the incorrect version in your EFI can cause degraded speeds or system freezes.
3. Use Offline Installer: Instead of using the online recovery method, create a full offline USB installer on a real Mac or a working Hackintosh. This installs macOS locally without needing an active internet connection during the initial stages.
