macOS System Info settings
Device details, advanced settings, and activation status.
- Date & TimeDate & Time settings keep your Mac's clock accurate by syncing automatically with a network time server, or let you set the date, time, and time zone manually when automatic detection isn't appropriate.
- About This MacAbout This Mac (accessible from the Apple menu) shows your Mac's model, chip or processor, memory, macOS version, and serial number at a glance, plus a detailed system report and storage breakdown for deeper troubleshooting.
- System ReportSystem Report (opened via the System Information app) provides a full technical inventory of your Mac — every connected device, installed application, network configuration, and hardware component — far beyond the summary shown in About This Mac. It's the tool Apple Support usually asks you to check when diagnosing hardware issues.
- Startup DiskStartup Disk lets you select which internal or external bootable volume your Mac uses when it powers on, useful if you have multiple macOS installations, a bootable backup, or a Windows partition via Boot Camp on an Intel Mac. Apple silicon Macs manage most of this through Startup Security Utility instead.
- Serial Number & CoverageThis is where you locate your Mac's serial number and check whether it's still covered by Apple's limited warranty or an AppleCare+ plan. You'll need the serial number for support calls, insurance claims, or verifying coverage before a repair.
- Sharing & Computer NameView and change the name your Mac uses on local networks and AirDrop, and manage which sharing services like File Sharing or Screen Sharing are enabled.
- Profiles (Device Management)See configuration profiles installed on your Mac by an employer, school, or manually, which can enforce settings like Wi-Fi configurations, restrictions, or MDM enrollment.
- macOS Version & Build NumberClicking the macOS version number in About This Mac reveals the exact build number, useful when a support agent, developer, or compatibility check needs more precision than the marketing version name.
- Legal & RegulatoryThe Legal & Regulatory page contains the macOS software license agreement, open-source acknowledgments, and regulatory certification marks required for different countries and regions.
