MacOS 10.13 High Sierra

Posted September 26, 2017

Hours before Apple was supposed to launch its new macOS version - codenamed High Sierra (10.13) - Patrick Wardle, a well-known Apple security researcher, former NSA hacker, and Chief Security Researcher at Synack, published a video demonstrating a zero-day exploit in the company's upcoming OS. Because of the focus on graphics - via a feature called Metal 2 - the new operating system will also allow developers to better take advantage of new technologies like machine learning and virtual reality. It's an over-the-air update you can access from the Mac App Store.

The High Sierra update for macOS is live.

The new implementation is already covered by the Device Analytics program that Apple offers up when users sign into their new macOS or iOS device.

"(On) High Sierra (unsigned) apps can programmatically dump (and) exfil keychain (with your plaintext passwords)", Wardle's tweet said.

There aren't many new features that come along with macOS High Sierra, but majority will surely improve the performance of your device. Wardle's app requires manual execution, but he told ZDNet that there's no reason it couldn't be reworked to be a hidden process in a legitimate-looking app.

Macs themselves don't have enough power to run VR content, but the site says High Sierra allows users to connect external graphics cards to their laptop or desktop computers to boost their performance. Users all around the world are enthusiastic to experience the new operating system on their existing Mac products.

MacOS 10.13 High Sierra is also meant to subject the EFI firmware of the Mac to a routine check on a weekly basis and to inform the user of any modifications.

Additionally, macOS High Sierra will also support High-Efficiency Video Coding (HEVC), a new standard that enables efficient compression, streaming and playback for video. There is also a new feature that stops ads from tracking you around the internet. 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. Apple's macOS High Sierra has nice features, feels fast, and just works. Valve is optimizing its SteamVR platform for macOS and the HTC Vive is now supported on Macs. So far Animoto, Shutterfly and Wix are confirmed Apple partners, with more likely to be added nearer full release.

If you rely on Adobe's apps don't upgrade to macOS High Sierra until compatibility issues are worked out. Version 61.0.3163.100 came out before High Sierra was released and it's compatible, too.
