If you don't plan on installing macOS High Sierra for whatever reason, your Mac will still inform you of the software update every now and then via persisting system notifications.
OS X El Capitan
Apple on Thursday issued Security Updates for OS X El Capitan and Yosemite. The releases patch multiple vulnerabilities that allow an application to disclose kernel memory, and executive arbitrary code with kennel privileges.
If this sounds familiar, it's because these are the same exploits patched in the latest iOS 9.3.5 update. Apple again credits Citizen Lab and Lookout research firms with the find, and recommends that all users install the updates.
A sixth major software update to OS X El Capitan 10.11 since its September 2015 debut is now available for public consumption as a free-of-charge release on the Mac App Store. To apply the update, launch the Mac App Store on your computer and click the Purchased tab: OS X El Capitan 10.11.6 should be sitting there, waiting for you to download it. If not, give it a few minutes or hours as new software takes some time to propagate across the Internet.
The parental controls on Mac allow you to have more control over your child's access, and they're an invaluable tool to make sure that they're only doing what they're supposed to be doing instead of everything they shouldn't.
Because many parents allow their children to use their Macs, it's a good idea to set parental control restrictions on their user account. We'll show you how this is done in this tutorial.
After seeding iOS 9.3.3 beta 2 and OS X El Capitan 10.11.6 beta 2 to the registered members of the Apple Developer Program yesterday, these new betas are now available to public beta testers who are signed on the Apple Beta Software Program.
Public beta testers can apply these updates through the Software Update mechanism on devices enrolled into the Beta program that run a prior iOS/OS X beta.
Spotlight Suggestions, a feature that recommends content from the Internet when searching with Spotlight on an iPhone, iPod touch or iPad with iOS 9.0+ or a Mac running OS X 10.11 El Capitan or later, has expanded to seven additional markets: Hong Kong, India, Luxembourg, Malaysia, Philippines, Singapore and United Arab Emirates.
Counting these regions, Spotlight Suggestions are now available in a total of 26 major markets around the world, listed on Apple's iOS Feature Availability webpage.
A new OS X extension from Hasbrang Productions, the prominent jailbreak community development team, makes it easy to open and switch a new Terminal window to the current working directory, right from the Finder's contextual menu.
Available at no charge on the Mac App Store, the aptly named TermHere installs itself as a Finder file extension, readily accessible from the right-click menu. It works as advertised and is pretty convenient, more so if you use Terminal frequently.
In addition to iOS 9.3.2, Apple on Monday released OS X 10.11.5, watchOS 2.2.1 and tvOS 9.2.1 to the public. You can find the updates in the Mac App Store, in the iOS Watch app, and by navigating to Settings > System > Software Updates > Update Software on your fourth generation Apple TV.
From what we saw in the various developer and public betas for the above updates, none of them are going to include any significant user-facing changes. They're mostly maintenance releases, featuring bug fixes and other improvements aimed at ironing issues noticed in previous software versions.
Among the plethora of built-in OS X features that help keep your Mac secure is something called File Quarantine, a download validation technology that checks any downloads for known malware when you try to open them.
File Quarantine is also available in compatible applications like Safari, Messages, iChat and Mail that download files from the Internet or receive files from external sources, such as email attachments.
Additionally, OS X blocks compromised versions of web plug-ins from functioning, including Java web apps and Adobe Flash content, to further limit your Mac's exposure to potential zero day exploits.
In this tutorial, we'll discuss how you can make sure that File Quarantine updates are turned on, which will allow your Mac to receive latest malware definitions and information about compromised web plug-ins from Apple.
Apple on Tuesday seeded brand new betas of the iOS, tvOS and OS X operating systems to members of the Apple Developer Program. iOS 9.3.2 beta 4 (build 13F68), tvOS 9.2.1 beta 4 (build 13Y772) and OS X El Capitan 10.11.5 beta 4 are all available for download on devices running earlier betas. Standalone installers can be downloaded through Apple's Dev Center for developers and are also available for public testing for members of the Apple Beta Software Program.
Should you ever find yourself in the need to create blank disk images, OS X's built-in Disk Utility is your friend. A disk image usually has a .dmg extension and appears, looks and behaves like any ordinary file, with one key exception: launching it prompts OS X to mount the volume on the desktop.
These mountable disk images can be useful in a number of situations. For example, you may want to create blank disk images for storage.
Furthermore, disk images can be used as a virtual disk for software distribution, to burn CDs or DVDs and so forth. In this step-by-step tutorial, you'll learn how to create blank disk images in Disk Utility, at any size, with optional password protection, formatting options and more.
Just 24 hours after iOS 9.3.2 beta 3 released to Apple's registered developers, the Cupertino company on Wednesday made the software available to public beta testers who are signed up for the Apple Beta Software Program. In addition, Apple posted new betas of tvOS 9.2.1 and OS X El Capitan 10.11.5 for members of its Apple Developer Program.
The new tvOS 9.2.1 beta 3 (build 13Y768) and OS X El Capitan 10.11.5 beta 3 (build 15F28b) can be obtained via Apple's portal for developers.
