Installing tvOS Betas Over-the-Air from iOS with iCab and Dropbox

I was trying to update my two Apple TVs (a 4K model and a 4th generation one) to the latest tvOS 11.2.5 beta earlier today to test AirPlay 2 (more on this soon) and, because I remembered there was a way to install tvOS betas without a USB-C cable, I was attempting to download Apple's tvOS beta configuration profile using Safari on iOS. However, as soon as I tapped the Download button on Apple's developer website, I got this message instead of a new tab showing the downloaded configuration file:

I don't know when Apple changed this behavior, but I recalled that Safari wouldn't try to install tvOS configuration profiles on an iOS device. Without a way to manually fetch the .mobileconfig file and save it to my Dropbox, I was going to unplug my TVs and connect them to my MacBook Pro (which usually sits in the closet until it's recording day for AppStories or Relay) to finish the process.

Apple Addresses the Meltdown and Spectre Exploits With Additional Mitigations to Come

In a support article, Apple has acknowledged that the recently-disclosed Meltdown and Spectre exploits, which affect virtually every CPU in computers, mobile devices, and other platforms, also impact every Mac and iOS device. Although there are no known exploits of the vulnerabilities, Apple advises that users proceed with caution and download apps from trusted sources only.

Mitigations to defend against Meltdown have already been shipped by Apple in iOS 11.2, macOS 10.13.2, and tvOS 11.2. watchOS is unaffected by Meltdown. Development of mitigations for both exploits is ongoing and new defenses will be released to each Apple OS as they become available.

The support article published by Apple provides a high-level explanation of how each exploit works. If there’s any good news to be found in the widespread concern caused by these exploits it’s that Apple says the recently-released mitigations have no measurable impact on performance:

Our testing with public benchmarks has shown that the changes in the December 2017 updates resulted in no measurable reduction in the performance of macOS and iOS as measured by the GeekBench 4 benchmark, or in common Web browsing benchmarks such as Speedometer, JetStream, and ARES-6.

Apple’s support document also reveals that Spectre can be exploited in web browsers, including Safari, using JavaScript. Apple is working to address the problem with an update to Safari that will be released in the coming days. Apple says that:

Our current testing indicates that the upcoming Safari mitigations will have no measurable impact on the Speedometer and ARES-6 tests and an impact of less than 2.5% on the JetStream benchmark.

The gravity of the exploits, which affect virtually all computing platforms, cannot be understated, but it’s reassuring that the initial mitigations released and those coming in the days ahead should have little or no impact on performance. It’s also worth noting that this is probably not the last we’ll hear about Meltdown and Spectre. As Apple notes:

We continue to develop and test further mitigations within the operating system for the Spectre techniques, and will release them in upcoming updates of iOS, macOS, tvOS, and watchOS.

tvOS 11.2 Introduces HDR and Frame Rate Options to Apple TV 4K and Sports Feature

Apple has released tvOS 11.2, which adds a new settings option to 4K AppleTVs that can automatically match the frame rate and dynamic range the content being played. The option, called ‘Match Content,’ is found under the Video and Audio section of the AppleTV’s Settings app. Under Match Content, users can choose to ‘Match Dynamic Range’ or ‘Match Frame Rate,’ which can automatically detect and set the original frame rate of content.

The fourth generation and 4K Apple TVs also gained a Sports tab in the TV app. The new section features live sports broadcasts and lets users pick their favorite teams to follow, get alerts when the score of an ongoing game is close, and view scores and schedules.


tvOS 11: The MacStories Review


WWDC was big this year, introducing new iPad and Mac hardware, Apple’s arrival into the smart speaker market with HomePod, and a variety of exciting software releases across iOS, macOS, and watchOS. But one of Apple’s main platforms was almost entirely overlooked: tvOS. During the WWDC keynote we received word that Amazon Prime Video would be coming to the Apple TV, but nothing else. Sessions held later in the conference revealed that a new version of tvOS did exist, and that it would be coming this year, but the details prove that it’s the smallest release in the OS’s young life. You could say that the focus of tvOS 11 is incremental improvements; the updates here are nice, but they hardly merit a major numbered release.

Joe Steel’s 2017 tvOS Wish List

Good follow-up by Joe Steel (who's been covering and critiquing the Apple TV for a while) to last year's tvOS wishes, which were already spot-on.

I found his assessment of the Siri Remote sadly relatable:

This remote was an abomination that should have never made it out of the design lab it was drafted in. It was conjured up by designers from another world who only had TV remote controls described to them using words in their native tongue. I want something that can be held comfortably, doesn’t shatter, and has asymmetry that you can feel to know what you are holding, and what you are pushing, without looking at the tiny monolith. I wanted it in 2015, and I still want it.

Whatever touch surface they include should be fine-tuned to work with a human thumb instead of whatever capuchin monkey the remote’s original designers were imagining.

Airfoil for macOS Regains Full Apple TV Compatibility

When Apple released tvOS 10.2 in late March, it broke audio streaming to the Apple TV from Rogue Amoeba’s macOS app, Airfoil. Since then, Rogue Amoeba has been working on two fronts to restore streaming to the Apple TV. The first results of those efforts were seen last month when Rogue Amoeba released a tvOS app called Airfoil Satellite TV that restored streaming as long as the app was running on your Apple TV.

Today, Rogue Amoeba announced that it has restored full Apple TV streaming functionality to Airfoil for macOS.

We’ve got a great update for Airfoil for Mac today which enables it to once again send audio directly to all versions of the Apple TV. Airfoil for Mac 5.6 is a free update, available immediately by selecting “Check for Update” from the Airfoil menu. We strongly encourage all users to move up to Airfoil 5.6 immediately.

With the Airfoil update, Airfoil Satellite TV is no longer necessary to stream to the Apple TV, but Rogue Amoeba plans to maintain it as a fall-back in case future tvOS updates break Airfoil streaming again.

Rogue Amoeba Releases Airfoil Satellite TV for the Apple TV

Airfoil by Rogue Amoeba is a Mac app that lets you stream audio from a Mac to multiple connected devices using technologies like Bluetooth and AirPlay. I reviewed version 5 of Airfoil last year, and was impressed with its ability to stream audio to every device I could find in my home and keep them in perfect sync.

Rogue Amoeba has done some impressive reverse engineering of Apple’s OSes to make Airfoil work. The upside is Airfoil is a remarkable audio hub for anyone who wants to stream audio to virtually any connected device. The downside is that changes to Apple’s OSes can break Airfoil, which is what happened when Apple released tvOS 10.2. That update broke Airfoil streaming to Apple TVs that updated to the latest version of tvOS.

Since tvOS 10.2 was released about a month ago, Rogue Amoeba has been working on two solutions for customers. The first is Airfoil Satellite TV, a tvOS app that was released earlier this week. The app, which can receive an audio stream from Airfoil for macOS, is available as a free download on the Apple TV App Store. When you open Airfoil Satellite TV on your Apple TV, a new audio destination appears in Airfoil on your Mac named ‘Airfoil Satellite on [Your Apple TV Name].’ Pick that destination and music starts streaming from your Mac to your Apple TV.

Apple Increases tvOS App Size Limit to 4 GB

Nice change for tvOS app developers announced today by Apple:

The size limit of a tvOS app bundle has increased from 200 MB to 4 GB, so you can include more media in your submission and provide a complete, rich user experience upon installation. Also, tvOS apps can use On-Demand Resources to host up to 20 GB of additional content on the App Store.

On one hand, this prepares the platform for 4K support and larger file sizes in the future, and it makes another step towards legitimizing the Apple TV as a micro-console (in addition to bigger app downloads, developers can also require controllers in their games for tvOS 10).

However, the 64 GB version of the 4th generation Apple TV has been around for over a year now with little explanation from Apple as to why customers would want to spend more for increased storage, and this feels like lifting a limitation because why not.

I'm curious to see what happens now, particularly in terms of game releases on tvOS. This is a welcome change for game developers, but we haven't seen any major tvOS exclusives so far.
