MacOS High Sierra security flaw puts your passwords at risk

The vulnerability is not limited to the latest version of the operating system, as Wardle also found it in older macOS and OS X versions, so holding off on upgrading to macOS High Sierra will not prevent users from being exposed to the exploit.

High Sierra also brings updates to Photos, provides support for virtual reality experiences, and improves Siri on the Mac.

But there's a bunch of smaller features that only diehard Apple fans will be able to spot. For macOS High Sierra, the shift to AFPS for any solid state storage based Mac makes this utterly vital, because if anything goes wrong as you shift file systems, you may be left with no way to recover your files.

KitGuru Says: Apple tends to take device security and user privacy very seriously, so this exploit will likely be patched out within the next couple of days.

What's here in High Sierra is fine.

App refinements have come aplenty for users as Photos gets a bunch of new features and even a refreshed editing UI. This helps ad makers tailor their content to reach more users.

Be sure you have enough space on your hard disk for the upgrade, as the installer alone is 5GB. You should see something similar to the screenshot below.

High Sierra will officially be available on 25 September.

Some of the features will probably be of interest to content developers: the new High-Efficiency Video Codec (HEVC), which adds better compression, streaming and playback. This delivers high-quality 4K videos with 40% less storage compared to H.264 standards. The operating system is compatible with Mac mini (2010 or later), Mac Pro (2010 or later), MacBook (2009 or later), MacBook Air (2010 or later), iMac (Late 2009 or later), and MacBook Pro (2010 or later).

Chances are, you'll find that High Sierra offers faster performance, but you might also run into some issues.

macOS High Sierra is more of a behind-the-scenes refresh rather than a brand new OS, but there are still some standout new features in the update.

One of the biggest new additions to the voice assistant is you can now ask it to play music for you. The Spotlight search tool can now be used to check airline flight times and status updates, for example, and the Mail app can use Spotlight to fine-tune searches and compile a list of "Top Hits" that prioritises emails from people in your VIP list or other frequent correspondents. There are new effects that can be added to Live Photos. When you send the link, the recipient simply needs to click on it to begin working, much like other cloud services such as Google Drive.
