Senior VP of software engineering at Apple, Craig Federighi, took to the stage at the new iPad Air announcement event to showcase the latest Mac operating system update: OS X Mavericks.
He also revealed a new MacBook Pro and Mac Pro.
The OS is said to be built on three main components: “core technologies, features to smooth the experience and apps.”
Federighi went on to state that just by installing Mavericks, Mac users could extend their battery life by an hour.
The OS also brings improvements for the iBooks app, which will allow users to view videos inside the book they are reading, and Calendar, which can extract information from messages and emails to automatically schedule appointments.
"It’s a fantastic release that extends your battery life, has some great new features and some really fun new apps,” said Federighi.
“It’s a new era for the Mac.”
Mavericks is free for Mac users, and is available now.
Following the Mavericks announcements, Apple senior VP Phil Schiller took the stage to reveal a new 13-inch MacBook Pro, which is powered by an Intel Haswell processor, and is claimed to have nine hours of battery life. The 13-inch MacBook starts at $1,299 (£801) and is available now.
A bigger brother to the 13-inch MacBook Pro was also revealed – the 15-inch MacBook Pro, which has a Crystalwell graphics chip and starts at $1,999 (£1234).
Apple then unveiled a new Mac Pro, which they say is powered by the fastest chip they’ve ever designed – the Intel Xeon E5 – and which also has the fastest memory ever produced by the company.
Joining the powerhouse components is 1TB of flash storage and dual workstation graphics, which Apple said is enough to power three 4K displays, while staying “astonishingly” quiet.
The Mac Pro starts at $2999 (£1850) with 12GB of RAM.
Apple also announced several updates and changes to its ‘iLife’ series of apps. The image app iPhoto has been redesigned with its Photobooks feature added to iPads.
iMovie has also been revamped, with several desktop features making their way onto its mobile versions.
The music production app GarageBand has also been redesigned, and can record up to 32 tracks on 64-bit devices.
The app features virtual musicians who can improvise and fill around user-created audio, but who can also be edited and adjusted by users.
The iLife updates are free and available today, and join a revamped set of iWork apps, which have had iCloud support added.
