New Apple File System Coming in macOS High Sierra Won’t Work With Fusion Drives

When macOS High Sierra is released to the public next week, the new Apple File System (APFS) feature will be limited to Macs with all-flash built-in storage, which means it won't work with iMacs that include Fusion Drives.

iMacs with Fusion Drives were converted to APFS during the beta testing process in the first macOS High Sierra beta, but support was removed in subsequent betas and not reimplemented.

With the release of the Golden Master version of the software, Apple has confirmed APFS will not be available for Fusion Drives and has provided instructions for converting from APFS back to the standard HFS+ format.


Public Beta testers who had an iMac with a Fusion Drive converted to APFS will need to follow a long list of instructions to convert back to HFS+, including making a Time Machine Backup, creating a bootable installer, and using Disk Utility to reformat their iMacs and reinstall macOS High Sierra.

Apple on September 5 published a support document confirming compatibility. When customers with an all-flash machine upgrade to macOS High Sierra install the update next week, their drives will be converted to AFPS. Apple explicitly says "Fusion Drives and hard disk drives aren't converted."

Apple says APFS will not be supported on Fusion Drives "in the initial release of macOS High Sierra," which suggests support could be added for Fusion Drives at a later date after lingering bugs are worked out.

Apple File System is a more modern file system than HFS+ and is optimized for solid state drives. It is safe and secure, offering crash protection, safe document saves, stable snapshots, simplified backups, and strong native encryption.


It's also more responsive than HFS+ with features like instant file and directory cloning, fast directory sizing, high performance parallelized metadata operations, and sparse file writes.

Apple plans to release macOS High Sierra on Monday, September 25.

Google Chrome Desktop Browser to Introduce Autoplay Blocking Features

Google will follow Apple's lead by adding an autoplay blocking feature to its desktop web browser in an update set to arrive in January, the company announced on Thursday.

One of the most common irritations of web browsing is unexpected media playback, which can eat up data allowance, consumer more power, and cause unwanted noise.

When Safari 11 is released as part of macOS High Sierra, Mac users will be able to control media playback settings on a per-site basis, ending the frustration of auto-playing media while browsing.

Starting in Chrome 64, Google's desktop browser will feature a customization option along the same lines. In a post on its Chromium blog, Google said that with the new settings, autoplay will only be allowed if the media on a website doesn't play sound, or if the user has frequently chosen to play media on the site before.
This will allow autoplay to occur when users want media to play, and respect users' wishes when they don't. These changes will also unify desktop and mobile web behavior, making web media development more predictable across platforms and browsers.
Since not all users have the same preferences for autoplaying media, Google said it would add a new user option in Chrome 63 to completely disable audio for individual sites that will persist between browsing sessions.

Based on the available evidence, Chrome's autoplay blocking options won't actually be as granular as Safari's, which will enable users to mute autoplaying media with sound, or block all autoplaying media completely, both for individual sites and globally.

According to Google's roadmap, Chrome's new autoplay policies will be rolled out by January 2018. macOS High Sierra – which includes Safari 11 – gets its public launch on September 25.

Google Backup and Sync App Updated With APFS Support for Macs Running High Sierra

Google this morning quietly updated its Backup and Sync client app with APFS support for Macs running the latest macOS High Sierra beta.

The change, first spotted by Piunikaweb, means users of Google Drive and Google Photos can now take advantage of the new Apple File System (APFS), which was introduced in High Sierra. APFS replaces HFS+ and unifies the file system across macOS, iOS, tvOS, and watchOS, meaning it's optimized for devices that use flash and solid-state storage.

Google's new Backup and Sync client app was broken by the OS change, and some High Sierra users resorted to moving their Google Drive to an external disk formatted to HFS+ to allow their files to sync again.

However, that step should no longer be necessary with Backup and Sync version 3.36. Users can take advantage of the new APFS support by either downloading the Google app anew or waiting for their client to auto-update sometime in the next week.

Google Backup and Sync for Google Photos and Google Drive is a free download for Mac.

Menu Bar Tools Bartender 3 and iStat Menus 5 Now Support macOS High Sierra

Surtees Studios recently announced it has released a public beta of Bartender 3 for testing on macOS High Sierra and macOS Sierra. It's a free update available within Bartender 2, which costs $15 after a free four-week trial.


The popular tool for rearranging or hiding Mac menu bar items has been completely rewritten in Swift, according to the release notes.

Bartender 3 also no longer requires the Bartender Helper to be installed in menu bar apps in order to control them. As a result, Bartender is no longer able to display the Bartender Bar beneath the menu bar—only within it.

The change was necessary since, in macOS High Sierra, Apple has apparently tightened its System Integrity Protection security feature, preventing system items like Spotlight search from being controlled by Bartender 2.

iStat Menus 5 was also recently updated with improved support for macOS High Sierra and MacBook Pro, MacBook, and iMac models released in 2017.


The popular Mac system monitor also gained improved per-process network monitoring, improved per-process memory monitoring in OS X El Capitan and macOS Sierra, improved Bluetooth battery monitoring, and improved disk monitoring performance, plus a fix for an issue with the sun position in light map.

iStat Menus is built into the macOS menu bar, providing power users with convenient access to system information, such as CPU and GPU usage, memory stats, fan speeds, temperatures, disk usage, and battery life.

iStat Menus 5 is $18 on developer Bjango's website, with a free 14-day trial available. The latest update is version 5.32.

Apple Invites Media to September 12 Event at Apple Park: ‘Let’s Meet at Our Place’

Apple today sent out media invites for its annual iPhone-centric event that will be held on Tuesday, September 12 at 10:00 a.m. at the Steve Jobs Theater at the company's new Apple Park campus in Cupertino, California. The media invites offer a first look at the theme of the event and feature the tagline: "Let's meet at our place." (via The Loop)


Apple's fall 2017 event will be its most significant in years thanks to the debut of a radically redesigned iPhone that features an edge-to-edge display, a vertical rear camera, facial recognition capabilities, a much improved processor, and wireless inductive charging functionality. The new iPhone features a display similar in size to the display of the 5.5-inch iPhone 7 Plus, but with a body closer in size to the 4.7-inch iPhone 7.

Along with a nearly bezel-free display, the device includes a glass body and is promised to be the most advanced, most revamped iPhone we've seen since the introduction of the iPhone 6 Plus in 2014. We expect the OLED iPhone, which is rumored to be more expensive than traditional iPhones, to be sold alongside two 4.7 and 5.5-inch LCD models that more closely resemble existing devices.

A dummy model featuring the upcoming OLED iPhone

The upcoming 4.7 and 5.5-inch iPhones have not been heavily featured in rumors, but they too are said to feature glass bodies, support for wireless charging functionality, and improvements to the processor, camera, and other components.

The iPhones aren't the only upgrades Apple will unveil at the event. Rumors suggest Apple will introduce a third-generation Apple Watch with an LTE chip that allows it to be decoupled from the iPhone. There's been some talk of a potential redesign, but it's sounding like the third-generation Apple Watch will look a lot like the Apple Watch Series 2.

At the event, we may hear more about upcoming products like the iMac Pro and the HomePod, and there could be one other major hardware surprise in store for us - a new 4K Apple TV. Hints of such a device have been spotted in firmware leaks and we've known Apple has had a new Apple TV in the works for some time.

As for other hardware, many iPads and Macs were refreshed in June, so we are not expecting any updates to the Mac and iPad lineups, but expect to see new Apple Watch bands and new iPhone cases.

We've already been testing next-generation operating systems including iOS 11, macOS High Sierra, tvOS 11, and watchOS 4, but following Apple's event, we may see some of these updates released to the public. iOS and watchOS updates are often released just ahead of new iPhones, while macOS updates tend to come somewhat later. tvOS 11 is such a minor update that it isn't clear when it'll be released, but it could come alongside the other updates. One thing we may not see -- an Amazon Prime Video app. There's one in the works, but word is it won't be ready in time.

In line with past events, Apple's 2017 iPhone unveiling will kick off at 10:00 a.m. Pacific Time. Apple will stream the event live on its website and on the Apple TV, but for those who are unable to watch, MacRumors will be providing full event coverage, both on MacRumors.com and through our MacRumorsLive Twitter account.

Apple Notifying Customers Using Older Pro Apps About Incompatibilities With macOS High Sierra

Apple today started sending out emails to customers who are using older versions of its pro apps to inform them about impending incompatibilities with macOS High Sierra.

MacRumors readers Lee and Dane both received emails letting them know that macOS High Sierra will not work with Final Cut Studio and Logic Studio, both of which are 32-bit apps that last saw updates in 2010.
Our records show that you may be using applications included in Logic Studio. We wanted to share some important compatibility information about these applications and macOS High Sierra, which will be available this fall.

Older versions of Apple pro music applications -- including applications in Logic Studio -- will not launch on a computer running macOS High Sierra.

New versions of Apple pro music applications -- including Logic Pro X and MainStage 3 -- are compatible with macOS High Sierra. You can purchase these applications on the App Store.
A support document linked in the email directs users to an article that further outlines which versions of Final Cut Pro X, Logic Pro X, and other software will work with macOS High Sierra.

According to the document, the following versions of pro apps are compatible with the macOS High Sierra update:

  • Final Cut Pro X 10.3.4 or later

  • Motion 5.3.2 or later

  • Compressor 4.3.2 or later

  • Logic Pro X 10.3.1 or later

  • MainStage 3.3 or later


Customers running earlier versions of these apps will need to update them to ensure compatibility with macOS High Sierra.

macOS High Sierra is in the final stages of testing and will see a public release this fall. The update brings many under-the-hood improvements, including a new file system, new high efficiency video encoding, a Metal 2 graphics API, support for eGPUs and VR content, and more.
