Lesson 26: Troubleshoot Peripherals Flashcards
• Manage peripheral connectivity. • Pair Bluetooth devices with your Mac. • Troubleshoot peripheral and driver issues.
What are the three primary peripheral bus technologies supported by Mac computers running macOS Big Sur?
macOS Big Sur supports these three primary peripheral bus technologies:
- Universal Serial Bus (USB)
- Bluetooth wireless
- Thunderbolt
What must occur for a Mac to communicate with a Bluetooth peripheral?
Where can you configure this pairing?
To communicate with a Bluetooth peripheral you must pair the Bluetooth device to associate it with your Mac.
Bluetooth preferences in System Preferences are responsible for pairing a Mac with Bluetooth peripherals.
You can quickly open Bluetooth preferences from the Bluetooth status menu.
What’s a device driver?
What are the four primary types of device drivers?
A device driver is software specially designed to facilitate the communication between macOS Big Sur and a peripheral.
The four primary types of device drivers are as follows:
- System Extensions
- Legacy system extensions (also referred to as third-party kernel extensions)
- Framework plug-ins
- Standalone apps
How does macOS Big Sur support third-party devices without needing third-party device drivers?
macOS Big Sur uses built-in generic drivers based on each device class.
For example, macOS Big Sur uses generic drivers for scanners and printers instead of third-party drivers.
What can you infer about a connected peripheral if it doesn’t appear in the System Information app?
If a connected peripheral doesn’t appear in System Information, the issue is probably hardware related.
Troubleshoot accordingly.
