Goodbye Mac OS X and hello macOS Sierra. Apple announced at WWDC 2016 that its new operating system for its Mac computers and MacBook laptops has been given a new name – and a lot of exciting new features, and if you can now download and install macOS Sierra right now.
Apple usually releases updates at 10:00 PDT (13:00 ET, 18:00 BST, 03:00 the next day AEST), so you’ll likely see the update appear now or soon after.
Siri, Apple’s virtual assistant, makes its debut on Apple’s desktop operating system, allowing users to control their Macs using just their voice. If you have an iPhone, then it will also work even better with your Mac running macOS Sierra thanks to improved Continuity features.
If you just can’t wait until later on today when macOS Sierra releases, it is available to download right now as a final release candidate from beta.apple.com.
The macOS Sierra final release candidate brings macOS Sierra that little bit closer to the final release, so if you’re thinking of downloading it, you’ll be faced with less issues than earlier versions.
The macOS Sierra final release candidate is still an early version of the software, however. The final release candidate is basically what the final release of macOS Sierra will look like, but it’s released early to make sure there are no major bugs. If there are, then these will hopefully be caught and fixed before macOS Sierra launches properly later on today, September 20.
This means that the macOS Sierra final release candidate will likely be very stable, but it’s still possible there will be bugs. If you want to make sure your Mac is completely safe, we’d strongly recommend waiting until the final stable release of macOS Sierra later this month.
Check your Mac can run macOS Sierra
Before downloading and installing the macOS Sierra final release candidate you’ll want to make sure that your Mac can run the new software. If you want to run macOS Sierra on a laptop you’ll need a MacBook from late 2009 or better, or a MacBook Air or MacBook Pro from 2010 or later.
If you’ve got an iMac, you’ll be okay with a model from late 2009 or better, and as for the Mac mini or Mac Pro, you’ll need one from 2010 or later.
Back up your Mac before installing macOS
Whenever you upgrade your operating system – and especially when you’re trying out a beta version – we highly recommend backing up the files on your Mac, so if anything goes wrong you can quickly restore your machine to its previous working order.
So, before you download and install macOS Sierra, make sure your Mac is backed up. For information on how to do this, head over to our ultimate guide to backing up your Mac
