Rtl8188eu Driver For Mac: How to Install and Use It
If you have a USB Wi-Fi adapter that uses the Realtek RTL8188EUS chipset, you may be wondering how to install and use it on your Mac. The RTL8188EUS is a single-chip 802.11bgn 2.4G wireless LAN controller that integrates a USB 2.0 interface and a 1T1R WLAN baseband and RF[^2^]. It is compatible with various devices such as TVs, set-top boxes, IP cameras, etc[^2^]. However, it may not work out of the box with your Mac, as it requires a specific driver and utility to function properly.
In this article, we will show you how to install and use the Rtl8188eu driver for Mac, which is a package that contains the driver and utility for Realtek 802.11n and 802.11ac USB Wi-Fi adapters[^3^]. This package supports macOS Ventura 13, macOS Monterey 12, macOS Big Sur 11, and macOS Catalina only[^3^]. It does not work on Mediatek adapters or Macs with M1 or M2 chips[^3^]. It also requires you to disable SIP (System Integrity Protection) security on your Mac before installing it[^3^]. We will explain how to do that in the following steps.
Step 1: Disable SIP Security on Your Mac
SIP (System Integrity Protection) is a feature that protects your Mac from malicious software by restricting the access of certain processes to system files and folders. However, it also prevents some third-party drivers and utilities from working properly, such as the Rtl8188eu driver for Mac. Therefore, you need to disable SIP security on your Mac before installing the driver.
To disable SIP security on your Mac, you need to boot into Recovery Mode first. To do that, restart your Mac and hold down Command+R keys until you see the Apple logo or a spinning globe. Then, select your language and click on Utilities > Terminal from the menu bar. In the Terminal window, type csrutil disable and press Enter. You should see a message saying that SIP is disabled. Then, restart your Mac normally.
Step 2: Download and Install the Rtl8188eu Driver for Mac
Once you have disabled SIP security on your Mac, you can download and install the Rtl8188eu driver for Mac from this GitHub repository[^3^]. The latest release is V15 as of December 14th, 2022[^3^]. You can download it by clicking on the Wireless-USB-Adapter-V15.zip file under Assets. Then, unzip the file and double-click on the Wireless USB Adapter.pkg file to start the installation process.
Follow the instructions on the screen to complete the installation. You may need to enter your administrator password and allow some system extensions during the process. The system will also reboot after the installation is finished. After the system boots up and you enter the system, you should see a new icon on your menu bar that looks like a Wi-Fi signal with an R letter on it. This is the utility for managing your USB Wi-Fi adapter.
Step 3: Configure and Use Your USB Wi-Fi Adapter
To configure and use your USB Wi-Fi adapter, click on the utility icon on your menu bar and select Open Wireless Utility from the drop-down menu. This will open a window that shows you the available wireless networks around you. You can scan for networks by clicking on the Refresh button at the bottom left corner of the window. You can also switch between different modes (Station or AP) by clicking on the Mode button at the top right corner of the window.
To connect to a wireless network, select it from the list and click on Connect at the bottom right corner of the window. You may need to enter a password or other credentials depending on the security type of the network. Once connected, you should see a green check mark next to the network name and an IP address assigned to your adapter at the bottom of the window. You can also check your connection status by hovering over the utility icon on your menu bar.
