What is a kext file and how does it work on Mac OS?

A kext file is a kernel extension file that extends the functionality of Mac OS's kernel, which is the core part of the operating system. Kext files are similar to drivers on Windows, and they allow the kernel to communicate with your computer's hardware. Most of the time, these files are installed automatically by Mac OS or by third-party software, and they require no maintenance. However, sometimes you might need to install or remove a kext file manually, especially if you are using a Hackintosh or a custom-built Mac.

What is io80211family.kext Catalina and what does it do?

io80211family.kext Catalina is a patched version of the original io80211family.kext file that comes with Mac OS. This file is responsible for managing the wireless network interface on your Mac, such as Wi-Fi or Bluetooth. The original file only supports certain wireless network adapters that are officially compatible with Mac OS, such as those from Apple or Broadcom. However, some users might have different wireless network adapters that are not supported by Mac OS, such as those from Atheros or Intel. In that case, they might experience problems with their wireless network connection, such as low speed, instability, or no connection at all.

To solve this problem, some developers have modified the original io80211family.kext file to add support for more wireless network adapters that are not officially supported by Mac OS. One of these modified files is io80211family.kext Catalina, which is specifically designed for Mac OS Catalina (version 10.15). By using this file, you can enable some unsupported wireless network adapters to work on Mac OS Catalina, such as those from Atheros or Intel.

What are the benefits of using io80211family.kext Catalina on your Mac?

By using io80211family.kext Catalina on your Mac, you can enjoy the following benefits:

You can use your existing wireless network adapter without having to buy a new one that is compatible with Mac OS You can improve your wireless network performance, such as speed, stability, and range You can access more features and settings of your wireless network adapter, such as changing the frequency band, channel, or mode You can avoid potential conflicts or compatibility issues with other kext files or software on your Mac

Of course, using io80211family.kext Catalina also comes with some risks and drawbacks, such as:

You might violate the terms and conditions of Mac OS or your wireless network adapter manufacturer You might encounter some bugs or errors that are not present in the original file You might need to update or reinstall the file whenever Mac OS updates or changes its kernel

Therefore, you should use io80211family.kext Catalina at your own discretion and responsibility, and always backup your data and system before making any changes.
