Plus, SSDs have different failure characteristics than hard disk drives - one bad bit and buh-bye - so the file system needs different types of redundancies and checks for reliability.

At the very least, AFS' 64-bit addressing is essential to the upcoming iMac Pro for many reasons, not the least of which is the ability to support that system's configuration with a 4TB SSD and higher.

The successor to the ancient HFS+ file system, Apple File System (AFS), was rolled out last year, but with High Sierra became the default.

In order to be able to work with iOS 11's new file encodings - the HEIF (photos) and HEVC/H.265 (video) which allow for better compression to save space on your iPhone - Apple had to update MacOS to understand them.When it comes down to it, many of them Apple really couldn't put off. There's a lot going on under the hood to lay the groundwork for future enhancements, though much of their benefit doesn't appear at the moment.

(If your Mac was built in the last seven or eight years, you should be good to go.) It flips the switch on overdue architectural changes If you never updated to Sierra, check out Apple's compatibility list. High Sierra has the same requirements as Sierra, so if you're running that now the answer's yes.

It's a free upgrade that works on 2010 and later Macs Want a more detailed look at what you need to know about High Sierra? Read on. That said, my standard recommendation is to wait at least a month before updating and let the early birds find the most glaring problems and glitches, which are generally handled by followup point upgrades. Updating will also get you the latest security fixes (the Keychain exploit above notwithstanding).

You've been screaming for the specific capabilities added in those particular applications.

You have a complicated family to manage with iCloud.

You've updated your iPhone or iPad to iOS 11 and shoot photos and videos with the new file formats.

Your system has an SSD, not a Fusion Drive or HDD.

But if you think the potential security advantages outweigh the possibility of running into application issues, then update. Enterprises are running even older versions and they'll continue to be patched. Some say that the update is essential in order to get a complete set of security fixes, but it's not like Apple is going to keep Sierra unpatched. Yes, if you answer any of these affirmatively: However, because the vulnerability is said to affect High Sierra and previous versions of MacOS, waiting to update won't make you any safer. Oopsie.ДЄpple did not provide a timeline for a possible fix. But it also turns out that High Sierra breaks one of our benchmarks. That's really important if you work with video and other massive-file generating tools.Д«attery life seems to be slightly better - we got about 30 minutes more.

File moves are instantaneous under both High Sierra and Sierra, but copies of large files (like a 4.3GB ISO image) are instantaneous on AFS, the updating disk file system that's now default for anyone who doesn't have a Fusion drive or an old spinning hard drive. Performance is virtually identical, at least on an up-to-date MacBook Pro (13-inch). On the other hand, that means no sea-changes to your existing workflows, and some nice quality-of-experience enhancements if you're a big user of those applications. Instead, you get new features such as Safari's autoplay blocking, the ability to edit iPhone's Live Photos in Photos, and really fast file copying on SSDs. That's largely the case with MacOS 10.13, otherwise known as High Sierra.ДЇor the most part, don't expect jaw-dropping changes or totally new interfaces. Now that they're free, operating system updates are often just as much about fixing the underlying plumbing of a device as they are about adding new and notable features. The older hardware had a pretty good run, but it's always sad when the end of a computer's useful life is dictated by Apple rather than by the userВ who bought the machine.Photos in High Sierra now has all the adjustment tools easily accessible on the side panel. Many of these Macs were already missing out on Yosemite and El Capitan-era features like AirDrop, Continuity, and the Metal graphics API.ДЄpple typically supports older OS X releases with security updates for a couple of years, so theoretically youВ canВ use El Capitan Macs without fear of security holes until 2018 or so (well, without fear of security holes that aren't also present in newer OS versions, anyway). Older Macs, mostly models from 2007, 2008, and 2009, won't run this fall's newВ macOS Sierra. SAN FRANCISCO, Calif.-For the first time since Mountain Lion was released in 2012, a new Mac operating system release will endВ support for older hardware.
