CUPERTINO, Calif. (AP) — Apple unveiled a thinner iPad Thursday with a faster processor and a better camera as it tries to drive excitement for tablets amid slowing demand. The company also released an update to its Mac operating system and introduced a high-resolution iMac model that might appeal to heavy watchers of television over the Internet.

The new iPad Air 2, at a quarter of an inch “thin,” also adds many of the features previously available on iPhones. That includes the ability to take burst shots and slow-motion video, and unlock the device with a fingerprint ID sensor instead of a passcode.
