Overview
This lecture covers the main configuration options available in Mac OS System Preferences, including display, network, privacy, accessibility, and backup settings.
System Preferences Overview
- System Preferences in Mac OS is the main location for configuring operating system settings.
- It is similar in function to the Windows Control Panel.
Display Preferences
- Display preferences manage settings for all monitors connected to the Mac.
- Users can arrange monitors, move menus between screens, and set resolutions and brightness.
- Detailed color grading options are available for each monitor.
Network Settings
- Mac OS network options cover both wired and wireless configurations.
- Users can set IP addresses manually or use DHCP for automatic assignment.
- Advanced settings include DNS, 802.1x authentication, proxies, and hardware configurations.
- Ethernet adapter settings allow modifications to TCP/IP, DNS, and proxy information.
Printers and Scanners
- Mac OS allows configuration for network and locally connected printers.
- Printers can be shared with others or have permissions modified.
- Users can check printer queues, view required supplies, and monitor toner or ink levels.
Privacy and Security Settings
- Users control what data and services applications can access, such as location or files.
- Software requests permission for access to sensitive resources like the microphone or camera.
- Permissions can be granted or denied for each application, enhancing privacy.
Accessibility Options
- Accessibility settings adjust how the system displays and communicates information for users with special needs.
- Features include visual, audio, and input modifications.
- Third-party accessibility apps may require extra permissions, which can be managed here.
- Each accessibility sub-category (e.g., zoom) offers specific settings, like zoom shortcuts and gestures.
Time Machine Backups
- Time Machine settings can be configured for backup storage drives, both local and networked.
- Automatic hourly, daily, and weekly backups are created and managed.
- The system deletes oldest backups as space runs out to continue saving new data.
