How to fix Wifi & Bluetooth driver in Mac OS Hackintosh High sierra

Wifi and Bluetooth are two important wireless technologies that are used in Macs. Both technologies are used to connect devices wirelessly to each other or to the internet. Wifi is used to connect to the internet and Bluetooth is used to connect to devices such as keyboards, mice, headphones, and other accessories.

If you are having issues with your Wifi or Bluetooth connection like network diagnostics on High Sierra, there are a few things you can do to try and fix the problem.

First, make sure that both your Wifi and Bluetooth adapters are turned on and working properly. To do this, go to the System Preferences and then click on the Network preferences. In the Network preference pane, make sure that the Wi-Fi and Bluetooth options are both selected.

If your Wifi and Bluetooth adapters are turned on and working properly, the next thing to do is to try and connect to a different Wifi network or Bluetooth device. This will help you to rule out any problems with the specific Wifi network or Bluetooth device you were using.

If you are still having issues with your Wifi or Bluetooth connection, you can try resetting your Wifi or Bluetooth adapter. To reset your Wifi adapter, go to the System Preferences and then click on the Network preference. In the Network preference pane, click on the gear icon at the bottom of the list of network adapters. This will open up a menu with a number of options. Select the “Reset” option and then click on the “Apply” button.

After you have reset your Wifi or Bluetooth adapter, try connecting to a Wifi network or Bluetooth device again. If you are still having issues, you can try restarting your computer. Sometimes, a simple restart can fix minor Wifi or Bluetooth issues.

If you are still having issues with your Wifi or Bluetooth connection, you may need to take more drastic measures. One option is to reinstall macOS. This will delete all of your files, so be sure to back up your data before you proceed. Another option is to install a new copy of macOS on an external drive.
