Apple Seeds Second Beta of macOS 12 Monterey to Developers

Monday June 28, 2021 11:09 am PDT by Juli Clover

Apple today seeded the second developer beta of macOS Monterey, the newest version of the macOS operating system. The second beta comes three weeks after Apple released the first beta following its WWDC keynote event.

macOS Monterey on MBP Feature
Registered developers can download the beta through the Apple Developer Center and once the appropriate profile is installed, betas will be available through the Software Update mechanism in System Preferences.

As with all new betas, Apple recommends not installing the new macOS update on a primary machine because it is early release software and could have bugs.

macOS Monterey introduces Universal Control, a feature that lets a single mouse, trackpad, and keyboard be used across multiple Mac or iPad devices, plus there's a new AirPlay to Mac feature.

Safari has been redesigned with a new tab bar and support for Tab Groups, and FaceTime has gained spatial audio, a Portrait Mode on M1 Macs, and Voice Isolation for cutting out background noise. There's also a new SharePlay ‌FaceTime‌ feature that lets Apple users watch TV, listen to music, and share their screens with one another.

Shared With You, a separate feature, keeps track of the music, links, podcasts, news, and photos that people are sent in Messages, highlighting it in the relevant apps. Notes has a new Quick Note feature for jotting down thoughts, and collaboration is easier with mentions and an Activity View.

The Shortcuts app from iOS is now available on the Mac, and Focus helps people stay on task by cutting out background distractions. There's an updated Maps app with a whole slew of new features, and with Live Text, Macs can now detect text in photos or provide details on animals, art, landmarks, plants, and more in images.

Mail Privacy Protection hides IP and prevents tracking through invisible pixels, and iCloud Private Relay keeps Safari browsing protected. There are many other new features in macOS Monterey, with a full rundown available in our macOS Monterey roundup.

‌‌macOS Monterey‌‌ is only available to registered developers right now, but in July, Apple will the Monterey beta available to its public beta testers.

The Touch Alternatives preference is automatically added to all iPad and iPhone apps when running on a Mac with Apple silicon. This feature makes it possible to use the keyboard to simulate swipes, taps, and drags, as well as device tilt; it also maps touches from the trackpad directly into the app when you hold down the Option key.

* Developers can automatically enable this feature for their app by default, by adding a properly configured com.apple.uikit.inputalternatives.plist to the app bundle. An onboarding dialog is shown on first launch in this case.

[HEADING=3]New Features in macOS Monterey 12 beta[/HEADING]

* The default Accept-Language header that doc://com.apple.documentation/documentation/foundation/urlsession sends has an updated format and corrected values for multiple locales. In addition to the preferred language, the header also includes the current system language as a fallback if it differs from the preferred language. This behavior affects apps that link against macOS 12, iOS 15, tvOS 15, and watchOS 8 SDKs. (38772422)
* URLSession now includes async functions. (68890254)
For example, a one-shot fetch:

let (data, response) = try await URLSession.shared.data(from: URL(string: "https://www.apple.com")!)
if let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 {
// Use data.
}
And support for an AsyncSequence stream of bytes:

let (bytes, response) = try await URLSession.shared.bytes(with: URL(string: "https://www.apple.com")!)
if let httpResponse = response as? HTTPURLResponse, httpResponse.statusCode == 200 {
for try await line in bytes.lines() {
// Parse line.
}
}

[HEADING=3]Swift[/HEADING]
[HEADING=3]New Features in macOS Monterey 12 beta[/HEADING]

* doc://com.apple.documentation/documentation/foundation/attributedstring is now available with the same character-counting behavior as Swift string. It is fully localizable, and also includes support for Markdown, Codable, strongly typed attributes, and more. (27227292)
* doc://com.apple.documentation/documentation/foundation/notificationcenter includes the AsyncSequence API for receiving notifications using async/await. (74401384)

for await note in NotificationCenter.default.notifications(named: .MyNote) {
// use note.
}

[HEADING=3]SwiftUI[/HEADING]
[HEADING=3]New Features in macOS Monterey 12 beta[/HEADING]

* LocalizedStringKey can now contain Markdown syntax. The system parses Markdown strings when you create a Text view from a LocalizedStringKey, including Text views created with a string literal. The system styles Text according to Markdown constructs. (74515884)
* You can create Text from an doc://com.apple.documentation/documentation/foundation/attributedstring structure. Text respects the styles you provide through attributes within the SwiftUI attribute scope; these styles take precedence over styles you provide through view modifiers. (74841755)
* Specific kinds of animations now execute off the main thread, so there are new thread-safety requirements. (70524799) Ensure the following functions and types are thread-safe:

* All methods and accessors of types conforming to these protocols: AlignmentID , Animatable , EnvironmentKey , EnvironmentValues , Equatable , GeometryEffect , doc://com.apple.documentation/documentation/swift/hashable, doc://com.apple.documentation/documentation/swift/identifiable, PreferenceKey , Shape , VectorArithmetic.
* Any closures you pass to the following types and functions, but only if the views that created them don't have references to ObservableObject types: ForEach , GeometryReader , backgroundPreferenceValue(_:_:) , overlayPreferenceValue(_:_:) , transformPreference(_:_:) , anchorPreference(key:value:transform:) , transformAnchorPreference(key:value:transform:) , transformEnvironment(_:transform:) , transaction(_:).

* A TextField provided an doc://com.apple.documentation/documentation/foundation/nsformatter now updates its binding as the user types. NSFormatter formats the text of the field when the user submits the field, or when focus moves away from the field. (67899823)
* The global coordinate space on macOS is now the top left corner of the window, consistent with other platforms. On previous versions of macOS, or when linked on a SDK prior to macOS 12, the globalspace had a flipped origin of the bottom left corner of the window. Check for its uses in conjunction with components such as GeometryReader. (65037389)
* Plain text fields will no longer draw focus rings. (51896032)
* Sidebars in Mac Catalyst now have a material background and a native row height. (65388682)
* A DisclosureGroup now toggles its expansion when tapping on the entire row. (62208702)

[HEADING=3]Resolved in macOS Monterey 12 beta[/HEADING]

* Fixed an issue that occurred when creating a Colorfrom a UIColor or an doc://com.apple.documentation/documentation/appkit/nscolor. This process now uses the explicit init(uiColor:)or init(nsColor:) initializers. Give preference to the Color standard-system colors over the equivalent from UIColor or NSColor. For example, use blue over the visually equivalent systemBlue. (73987059)
* Fixed an issue that dispatched a callback for onAppear(perform:) and onDisappear(perform:) when any of the views in a group of multiple views appeared or disappeared. Now, when you apply them to a group of multiple views, onAppear(perform:) and onDisappear(perform:) only dispatch the callback each time the first view appears and the last view disappears. (75609476)
* Fixed an issue with labeled views that distributed the space in the view equally between controls. When laid out horizontally, labeled views now prioritize displaying the label fully before distributing space to the rest of the controls. (74728764)
* Fixed asset catalog images with the Preserve Vector Representation option set so the images work correctly when resized by re-rendering from their vector source. (49074629)
* Symbol images in Widgets and watchOS complications are now redrawn from their vector outlines, avoiding pixellation. (50464514)
* Updated BackgroundStyle and the new background modifier to include desktop tinting in Dark Mode as expected. (71062814)
* Fixed keyboard shortcuts using an uppercase key so they no longer have an implicitly added ⇧ modifier. (68047066)
* An app using the SwiftUI app lifecycle will no longer attempt to load the main storyboard file if one is set in the Info.plist file. (72819768)
* Commands bodies are now automatically updated in response to changes in dynamic property values used in the body definition. Types like State and FocusedValue can now be used to create dynamic dependencies in command content. (64788135)
* Fixed bordered buttons so they are clickable only by their label, not by the button chrome. (78192660)
* Updated Sheets to dismiss using the proper animation. (66393848)
* Fixed fileImporter and fileExporter to properly present when used in a Commands context. (77531659)
* Fixed nested ScrollViews with orthogonal scrolling directions, like a horizontal ScrollView inside of a vertical ScrollView, to scroll as expected. (54849400)

[HEADING=3]TabularData[/HEADING]
[HEADING=3]New Features in macOS Monterey 12 beta[/HEADING]

* TabularData is a new Swift framework you use to analyze and manipulate tabular data. You can use DataFrame to read CSV and JSON files, as well as join, group, and aggregate data. (69982458)

[HEADING=3]Virtualization[/HEADING]
[HEADING=3]New Features in macOS Monterey 12 beta[/HEADING]

* Interfaces that previously took unsigned long long arguments or returned unsigned long longresults have been updated to use the uint64_t type instead. (77291339)

Good luck to all you beta-testers. Been one since the very early days of OS X - suffering through untold numbers of bone-crushing bugs that took forever (if at all) to be fixed, bug reports that over 95% of the time just went into a black hole, and accumulated months of my life wasted while I witnessed the slow and steady decline of Apple's software QC over the years. My new plan is to ride the Big Sur updates to the end and then my next update will be to the final version of Monterey, followed by only final versions of MacOS after that. I get a shiny new OS every year, and it'll always as rock solid as it gets. And all the software I use will also have had plenty of time to acclimate to the OS when I upgrade. Oh happy days - my turn to mooch off you :-).

I installed it but I don't even know what to test. Beta 1 was working perfectly for me. For those wondering, Safari looks completely the same.
