Monday, Apple seeded a third developer-only beta of macOS Sierra (build number “16A254g”) to members of the Apple Developer Program, followed by a version suited for public beta testers 24 hours later.
After spending some quality time with Sierra’s third beta, our own Andrew O’Hara summed up for you guys all the changes and fixes he’s discovered in Sierra’s beta 3 in a hands-on video.
Video hands-on: Sierra beta 3
In this hands-on video, Andrew goes through some of the more newsworthy fixes and changes in Sierra’s third beta. The video, embedded right below, runs four minutes and 28 seconds long.
Sierra beta 3 changelog
The following has been changed, fixed and improved in Sierra beta 3:
About This Mac
- The Storage tab in About This Mac may not load if a volume has been unmounted.
- The Purgeable and System sizes shown in the Storage tab of About This Mac may be incorrect.
- Watched iTunes movies, TV shows, and podcasts will not be automatically deleted even though Optimize Storage has been turned on.
- On systems with AMD graphics, the system print dialog appears as a black box.
- Creating an Apple Pay for Web PaymentRequest with shipping address + contact will bring up the payment sheet on iPhone but it will quit unexpectedly.
- Apple Pay on the web transactions will not complete successfully on MacBook Air and MacBook Pro.
- Users may experience no internet connectivity after a successful Auto Unlock, followed by a reboot of their Mac.
Back to my Mac
- Back to my Mac cannot be started for some users.
- The input and output data for the CIImageProcessor API is now ordered so the the upper-left-most pixel is the first byte in the buffer.
- If your iCloud storage is full, and you have items that have not yet uploaded to the cloud, you need to force quit and relaunch iBooks in order to proceed with a storage upgrade.
- Using the Trackpad Handwriting feature for Chinese may not work reliably when using trackpads that do not support Force Touch.
- When using the Pinyin input method to type Chinese, uppercase typing incorrectly produces full-width Latin letters. Additionally, some of the keys may not produce the expected punctuation symbols.
- Recovery install fails when Safari is used in Recovery environment.
- Systems with FileVault enabled may hang at the login screen after updating.
- Files attached to a blank email from 3rd-party applications may not be attached.
- Adding an attachment, or deleting or moving notes may cause Notes to quit unexpectedly.
- Search results for people are incorrect.
- Comment badges may not appear in Shared Albums.
- Safari may quit unexpectedly if the Smart Search field is clicked with no History or while History is still loading.
- Users may encounter errors while sending Messages with Siri using relationships or during contact disambiguation.
- Using Siri to search for Photos taken in a specific location has limited support.
- When searching for photos with Siri, users may not see search results in the Photos app after it launches.
- Responses are not supported in Malaysian.

It’s called beta for a reason
We already received complaints from some beta testers that the third beta lacks the “Allow your Apple Watch to unlock your Mac” checkbox in Security and Privacy preferences. This happens after an erase install—Apple acknowledges that “it can take minutes” for the checkbox to show up due to first-time iCloud pairing between devices.
This is normal, and does not happen on upgrade installs.
Additionally, FaceTime calling between Sierra beta 3 and prior iOS and macOS betas is unsupported, iTunes 12.5 doesn’t display artwork for rented movies, SMB is now the default file-sharing protocol (not AFP), Live Photos refuse to play back in Photos, AirDrop is unreliable, file search queries are not supported for some languages and so forth.
See, they call it a beta for a very good reason…
Check out some of the coolest Sierra features
The first public beta of Sierra was released earlier this month, giving folks who enrolled in the Apple Beta Software Program a chance to play with some of the major new features. To clear up any confusion, let me state for the record that the second public Sierra beta and the third developer-only beta offer the same features.
Some of the more interesting changes in developer-only beta 3 (and public beta 2) include a new default keystroke for Siri, the ability to unlock a Mac awoken from sleep by wearing an Apple Watch, iTunes 12.5 and other tidbits highlighted in the video below.
Check out our write-up for detailed overview of the changes discussed in the above clip.
Of course, we must not forget to mention other headlining features in Sierra:
- Siri for Mac
- Deeper integration with iOS through expanded Continuity features
- Desktop and Documents sync via iCloud Drive
- The ability to copy and paste text and media from one Apple device to another
- Photos app with a new Memories feature that uses advanced objet recognition
- Safari 10 with Picture-in-Picture, native Extensions and Apple Pay on websites
One of the awesome new Continuity features is Universal Clipboard—which works like magic, really—and the ability to have the contents of your desktop and the Documents folder synced via iCloud and available across iOS devices via the iCloud Drive app.
Plus, Apple Watch owners are going to be absolutely thrilled by Auto Unlock.
For more goodies, see our in-depth Sierra previews:
- Changes and fixes in beta 2
- Simulating ‘Hey Siri’ on Sierra using Dictation tricks
- Siri comes to the Mac
- Auto Unlock your Mac with Apple Watch
- Universal Clipboard + Desktop & Documents sync
Sierra has a lot to offer so many people should fall in love with it.
Our macOS Sierra Preview series will soon highlight additional features.
macOS Sierra was initially made available as a developer-only preview to members of the Apple Developer Program in June before releasing for public beta-testing in July.
The operating system will release for public consumption this fall as a free software update via the Mac App Store. macOS Sierra has been confirmed to support a smaller number of Macs.
Compatible Mac models for Sierra include late-2009 and later MacBooks and iMacs and 2010-and-later MacBook Airs, MacBook Pros, Mac minis and Mac Pros. Macs manufactured before 2009 won’t be supported.
