These advanced steps are primarily for system administrators and others who are familiar with the command line. You don't need a bootable installer to upgrade macOS or reinstall macOS, but it can be useful when you want to install on multiple computers without downloading the installer each time.

The Ralink USB Driver software package is designed to help you use the Ralink wireless devices with your Mac computer. The software creates a communication path between the operating system and the device, so you should be able to take full advantage of its capabilities. Aug 21, 2019 - Blueshadow AC600 USB WiFi Adapter driver is a software that allows the OS to communicate with Blueshadow AC600 USB Wifi Adapter. Download here for free. Once identified use Google to search for Apple Mac OS drivers for your WiFi chipset/product, in my case this was a RTL8191SU based dongle and it had a working Apple Mac OS X driver for the most current Mac OS X Mountain Lion version (Apple Mac OS X 10.8.4). A simple download and install, followed by a reboot did the trick as shown below. 5.After MAC is rebooted, please click the Wi-Fi icon to “Open Wireless Utility”, then you can choose your Wi-Fi and connect it. (Note: it may take time for utility to search W i-Fi, please wait patiently for about 1 min.) Now please enjoy your W i-Fi.

Download macOS

Find the appropriate download link in the upgrade instructions for each macOS version:

macOS Catalina, macOS Mojave, ormacOS High Sierra
Installers for each of these macOS versions download directly to your Applications folder as an app named Install macOS Catalina, Install macOS Mojave, or Install macOS High Sierra. If the installer opens after downloading, quit it without continuing installation. Important: To get the correct installer, download from a Mac that is using macOS Sierra 10.12.5 or later, or El Capitan 10.11.6. Enterprise administrators, please download from Apple, not a locally hosted software-update server.

OS X El Capitan
El Capitan downloads as a disk image. On a Mac that is compatible with El Capitan, open the disk image and run the installer within, named InstallMacOSX.pkg. It installs an app named Install OS X El Capitan into your Applications folder. You will create the bootable installer from this app, not from the disk image or .pkg installer.

Use the 'createinstallmedia' command in Terminal

1. Connect the USB flash drive or other volume that you're using for the bootable installer. Make sure that it has at least 12GB of available storage and is formatted as Mac OS Extended.
2. Open Terminal, which is in the Utilities folder of your Applications folder.
3. Type or paste one of the following commands in Terminal. These assume that the installer is still in your Applications folder, and MyVolume is the name of the USB flash drive or other volume you're using. If it has a different name, replace MyVolume in these commands with the name of your volume.
   Catalina:*
   Mojave:*
   
   High Sierra:*
   El Capitan:
   
4. Press Return after typing the command.
5. When prompted, type your administrator password and press Return again. Terminal doesn't show any characters as you type your password.
6. When prompted, type Y to confirm that you want to erase the volume, then press Return. Terminal shows the progress as the bootable installer is created.
7. When Terminal says that it's done, the volume will have the same name as the installer you downloaded, such as Install macOS Catalina. You can now quit Terminal and eject the volume.

* If your Mac is using macOS Sierra or earlier, include the --applicationpath argument, similar to the way this argument is used in the command for El Capitan.

Use the bootable installer

After creating the bootable installer, follow these steps to use it:

1. Plug the bootable installer into a compatible Mac.
2. Use Startup Manager or Startup Disk preferences to select the bootable installer as the startup disk, then start up from it. Your Mac will start up to macOS Recovery.
   Learn about selecting a startup disk, including what to do if your Mac doesn't start up from it.
3. Choose your language, if prompted.
4. A bootable installer doesn't download macOS from the Internet, but it does require the Internet to get information specific to your Mac model, such as firmware updates. If you need to connect to a Wi-Fi network, use the Wi-Fi menu in the menu bar.
5. Select Install macOS (or Install OS X) from the Utilities window, then click Continue and follow the onscreen instructions.

Older Macs may not have a slot for Apple’s AirPort Card, and even if yours does, you may want higher throughput than 802.11b WiFi offers – 802.11g will give you nearly five times as much bandwidth.

These WiFi adapters may well cost less than an AirPort Card, which tends to sell in the US$50-100 range nowadays.

This page covers USB, ethernet, PCI, and other WiFi hardware that is compatible with the Classic Mac OS. A few of these devices are compatible with Mac OS 8.6; all of them are reported to work with Mac OS 9, and most also have drivers available for some versions of Mac OS X.

PCMCIA/PC Card WiFi adapters compatible with Mac notebooks are covered in WiFi PC Cards for PowerBooks Running Mac OS 9.
