Newest Apple Os Update
If you shoot a snapshot, slo-mo, or selfie on your iPhone, it’s automatically added to iCloud Photos — so it appears on your Mac, iOS and iPadOS devices, Apple TV, iCloud.com, and your PC. Even the photos and videos imported from your DSLR, GoPro, or drone to your Mac appear on all your iCloud Photos–enabled devices. Help make the next releases of iOS, iPadOS, macOS, tvOS and watchOS our best yet. As a member of the Apple Beta Software Program, you can take part in shaping Apple software by test-driving pre-release versions and letting us know what you think.
Your Mac provides several tools to help you identify it. The simplest is About This Mac, available by choosing About This Mac from the Apple menu in the upper-left corner of your screen. The other is the System Information app. Learn how to use these tools to identify your Mac.
If you don’t have your Mac or it doesn’t start up, use one of these solutions instead:
- Find the serial number printed on the underside of your Mac, near the regulatory markings. It’s also on the original packaging, next to a barcode label. You can then enter that serial number on the Check Coverage page to find your model.
- The original packaging might also show an Apple part number, such as MMQA2xx/A (“xx” is a variable that differs by country or region). You can match the Apple part number to one in the list below to find your model.
