Why did this happen and what does it mean?
Apple has delayed the launch of its first mixed-reality headset from April to June due to hardware and software issues.
The company plans to unveil the product at its annual Worldwide Developers Conference (WWDC) in June, and then release it later in the year.
The mixed-reality headset combines virtual and augmented reality and will cost around $3,000.
The device will feature a new operating system called xrOS, with a 3D-like view of the iPhone interface, and a range of apps and an App Store.
The hardware includes a Mac-grade M2 chip, 4K virtual reality displays, and a complex array of cameras for augmented reality.
Apple is working on issues with sensors, battery life, and performance, and has offloaded the device's battery to an external pack that will sit in the user's pocket.
Apple engineers have expressed concerns that the device may be too expensive and that the market is still too nascent.
Apple is already planning a cheaper version with less powerful components for release in 2024.
Apple has indefinitely postponed work on standalone augmented reality glasses.
