Usb Wifi For Mac Os X

admin

Mar 12, 2020 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. Open Terminal, which is in the Utilities folder of your Applications folder. Type or paste one of the following commands in Terminal.

Usb Wifi For Mac Os XThanks for reviving the old DWL-G122 thread from a year ago and for the excellent summary! There are testimonials to the DWL-G122 at Amazon and numerous dongles for sale on ebay and a real need to sort out what works and what doesn't.

Some followup comments and questions:

  1. ROCKETKART 2.4Ghz, 600Mbps Wireless WiFi Adapter for pc with High Gain Antenna, Compatible with Windows XP/7/8/8.1/10 - MAC OS 10.710.13.
  2. Jan 13, 2019  Hey I need ur recommendations for mini usb wifi adapters like that in picture that can work perfectly in os x mojave or os x high sierra, plz help me! Mac OS X Support Mac Software Other Apple Hardware Laptops Laptop Compatibility.

1. One reason why you might be interested in a USB wireless antenna even if you've got a modern Mac with builtin wireless is that the reception on the Airport cards (at least in a titanium PowerBook like mine) is notoriously weak. There are lots of times when I get little or no reception and my pals with Dell laptops are doing great. I also want a cheap USB wireless device so I can play with gizmos like the famous Chinese cookware antenna.

2. Thanks for the warning that two antennas in use simultaneously can damage each other. But there's no problem as long as you turn off your built-in antenna before plugging in the USB one, right? Presumably you could avoid the problem by putting the USB antenna at the end of a cable, correct? How long would be far enough? And doesn't this problem also apply if people on two different laptops are working in close quarters?

3. So the Ralink driver trick only works with the B1 version of the G122. What if you can locate an older A1 or A2 version? Will they still work on Mac OS X 10.4? There seem to be plenty of them on ebay, although a lot of the sellers don't say and probably don't know which version they've got. (The ones who do so are trying to cater to TiVo users, who also have dependencies on the G122 version.)

4. Finally, are there any *other* USB wireless antennas which can be scrounged up cheap for use on a Mac? Don't answer that -- I'll start another thread.

Thanks again!

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.

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:

For
  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.
