    macOS Tahoe 26.5 Beta Release Notes

    macOS 26.5 adds SDK support for Tahoe 26.5 beta and brings new StoreKit pricing and billing plan APIs for subscriptions, including pricing terms, billing plan type, entitlement metadata, and built-in SwiftUI merchandising styles.

    Update your apps to use new features, and test your apps against API changes.

    Overview

    The macOS 26.5 SDK provides support to develop apps for Mac computers running Tahoe 26.5 beta. The SDK comes bundled with Xcode 26.5, available from the Mac App Store. For information on the compatibility requirements for Xcode 26.5, see Xcode 26.5 Release Notes.

    StoreKit

    New Features

    • You can read pricing information for subscriptions that have a monthly with 12-month commitment billing plan configuration in App Store Connect or StoreKit Testing in Xcode through the new PricingTerms model on SubscriptionInfo.pricingTerms. (150388310)
    • You can specify the billing plan type to use for subscriptions that have a monthly with 12-month commitment billing plan configuration using the new billingPlanType PurchaseOption. (150388542)
    • Read customer entitlement metadata for subscriptions purchased with a monthly billing plan type through the new CommitmentInfo data model on Transaction and SubscriptionRenewalInfo. (150388746)
    • When you import both StoreKit and SwiftUI, you can merchandise the monthly billing plan configuration for subscriptions that have a monthly with 12-month commitment billing plan using built-in styles through the new preferredSubscriptionPricingTerms(_:) API. (150389069)

    StoreKitTest

    Known Issues

    • SKTestSession cannot use the selected StoreKit configuration during unit tests, resulting in failed test actions. (172583218) (FB22237318)

    Workaround: To use SKTestSession in 26.3 and 26.4, build and run the app on device using the same StoreKit configuration as the test. Then close the app and run the unit test using SKTestSession without changing any configuration settings in the test environment. This allows the configuration to be saved on device before the test begins and maintain your selected configuration settings through the test session.

    macOS Tahoe 26.4 Beta Release Notes

    MacOS Tahoe 26.4 beta ships with Xcode 26.4 and adds offline asset status checks, local asset availability, MIDI 2.0 networking, and new StoreKit fields, along with various fixes and known issues.

    Overview

    The macOS 26.4 SDK provides support to develop apps for Mac computers running Tahoe 26.4 beta. The SDK comes bundled with Xcode 26.4, available from the Mac App Store. For information on the compatibility requirements for Xcode 26.4, see Xcode 26.4 Release Notes.

    AppKit

    Resolved Issues

    • Fixed: Window resize pointer does not follow the window’s corner shape. (149726089)

    Background Assets

    New Features

    • You can now check the status of an asset pack while offline by calling localStatus(ofAssetPackWithID:) or assetPackIsAvailableLocally(withID:) on the shared asset pack manager. The former method returns all available status information. The latter returns only a Boolean value but can be called synchronously. Not all status information is available offline. (164498466)
    • You can make the latest version of an asset pack available locally by calling ensureLocalAvailability(of:requireLatestVersion:) on the shared asset pack manager and passing true to the shouldUpdate parameter. (166237389)

    Known Issues

    • Setting a URL override could break apps from the App Store that use Apple-Hosted Background Assets. (169558509)
      Workaround: Remove any URL override that you previously set before installing or using an app from the App Store.
    • Apps might crash when downloading asset packs. (169648111)
      Workaround: If an app crashes due to this issue, then relaunch it. The app should then have local access to the asset pack that it was downloading when it crashed.

    CoreMIDI

    New Features

    • Audio MIDI Setup now supports Network MIDI 2.0 sessions in the redesigned MIDI Network Setup panel. You can create MIDI 2.0 connections over your local network using UDP transport for Universal MIDI Packets, enabling both Legacy MIDI and MIDI 2.0 protocol communication. Network MIDI 2.0 sessions appear alongside existing RTP MIDI sessions and support automatic device discovery through mDNS and data integrity features for reliable wireless performance. (118728162)

    External Boot

    Known Issues

    • When installing an external disk, some configurations of M1 Apple Silicon Macs might panic at boot. (170263142)
      Workaround: Install to a secondary volume in APFS container instead of external disk to validate secondary boot sequences.

    External Media

    Known Issues

    • HFS external media might fail to mount automatically. (168672160)
      Workaround: For macOS only, use CLI tool diskutil mount to attach the relevant disk device.

    Internet Accounts

    Known Issues

    • Exchange syncing for Calendar, Reminders and Notes might fail. (168082477)
      Workaround: To continue syncing Calendar and Reminders, disable Notes syncing in Internet Accounts.

    Login

    Known Issues

    • Touch ID might not be available to unlock the screen of a standard user account after updating to this release. This occurs when FileVault is enabled and a standard user account is logged in prior to any administrator logging in following the update. (169743642)
      Workaround: An administrator user should sign in to the Mac before any standard users.

    macOS Recovery

    Known Issues

    • When deleting a boot volume from the Activation Lock window in macOS Recovery, full erase functionality might not work. (170280070)
      Workaround: Use the “Erase All Content and Settings” functionality from the booted OS instead of triggering from recovery.

    Networking

    Resolved Issues

    • Fixed: Multiple processes leak CFRunLoopSource objects when Automatic proxy configuration (PAC) or Auto proxy discovery are configured.
      For clients of the CFNetwork ExecuteProxyAutoConfigurationURL and CFNetwork ExecuteProxyAutoConfigurationScript API, please check to make sure your process is not working around the leak by overreleasing the CFRunLoopSourceRef returned by those functions or the CFArrayRef and CFErrorRef passed to the completion. (166839810) (FB21376045)

    Resource fork

    Resolved Issues

    • On macOS 26.4 and later, file systems that do not natively support extended attributes restrict partial writes to the first 286 bytes of the resource fork extended attribute (com.apple.ResourceFork).
      To modify the resource fork, replace the entire 286-byte range, or write beyond the 286-byte offset. (156896699)

    Rosetta

    Deprecations

    • As announced at WWDC in 2025, macOS Tahoe 26 is the last release to support Intel based Macs. Additionally, Rosetta support for apps will end after macOS 27. Starting in macOS Tahoe 26.4, users will be notified when they launch apps that use Rosetta of the upcoming incompatibility.
      During the beta period, the cadence of notifications will be accelerated, enabling Apple and developers to address any issues that might occur.
      There will continue to be support for older, unmaintained gaming titles leveraging Rosetta along with software running Intel binaries in Linux VMs.
      Organizations using a device management service can control the notification experience with the allowRosettaUsageAwareness key. (169228455)

    StoreKit

    New Features

    • New fields revocationType and revocationPercentage have been added to Transaction. (148858551)

    SwiftUI

    Resolved Issues

    • Fixed: SwiftUI does not surface the latest .userActivity as the current user activity. (163136831)
    • Fixed: On macOS, a non-opaque window that hosts glass content will correctly update the backdrop content behind the glass even if the window is inactive. (166828089) (FB21375029)

    Known Issues

    • Multiple implicit SwiftUI animations (triggered by RealityViewContent.animate or Entity.animate) that modify a RealityKit component’s properties, are combined only when the implicit animations target the same set of component properties.
      For example, if you initiate an implicit animation on Transform.scale and then initiate an implicit animation on Transform.scale and Transform.translation then the animations affecting the scale property will be independent of each other, and will not combine. In this case, the most recently initiated animation will overwrite the scale property. (169723142)
      Workaround: Ensure the same component properties are animated by subsequent implicit animations when possible.

    Virtualization

    Resolved Issues

    • Fixed: On certain hardware configurations, new macOS Tahoe virtual machine installations may boot to a black screen. (169654019)

    iOS & iPadOS 26.4 Beta Release Notes

    Apple’s iOS iPadOS 26.4 beta SDK brings new asset management and safety features, plus messaging and StoreKit updates. You can check asset pack status offline, ensure local availability, and opt into Memory Integrity Enforcement. RCS end-to-end encryption is in beta for testing.

    Overview

    The iOS & iPadOS 26.4 SDK provides support to develop apps for iPhone and iPad running iOS & iPadOS 26.4 beta. The SDK comes bundled with Xcode 26.4, available from the Mac App Store. For information on the compatibility requirements for Xcode 26.4, see Xcode 26.4 Release Notes.

    Background Assets

      Workaround: If an app crashes due to this issue, then relaunch it. The app should then have local access to the asset pack that it was downloading when it crashed.

    External Media

    Known Issues

    • HFS external media might fail to mount automatically. (168672160)
      Workaround: For macOS only, use CLI tool diskutil mount to attach the relevant disk device.

    Feedback

    Known Issues

    • After submitting a crash/panic report, Feedback UI’s close button might become unresponsive. (170091186)
      Workaround: Locking and unlocking the device helps get out of this state.

    Memory Integrity Enforcement for Applications

    New Features

    • Applications can now opt in to the full protections of Memory Integrity Enforcement for enhanced memory safety protection. Previously applications were limited to Soft Mode. (160719439)

    Messages

    New Features

    • RCS end-to-end encryption is now available for testing in this beta. This feature is not shipping in this release and will be available to customers in a future software update for iOS, iPadOS, macOS, and watchOS. End-to-end encryption is in beta and is not available for all devices or carriers. Conversations labeled as encrypted are encrypted end-to-end, so messages can’t be read while they’re sent between devices. In this beta, RCS encryption is available for testing between Apple devices and is not yet testable with other platforms. (170160585)

    Networking

    Resolved Issues

    • Fixed: Multiple processes leak CFRunLoopSource objects when Automatic proxy configuration (PAC) or Auto proxy discovery are configured. For clients of the CFNetwork Execute Proxy Auto Configuration URL and CFNetwork Execute Proxy Auto Configuration Script API, please check to make sure your process is not working around the leak by overreleasing the CFRunLoopSourceRef returned by those functions or the CFArrayRef and CFErrorRef passed to the completion. (166839810) (FB21376045)

    Reality Composer

    Known Issues

    • Reality Composer iOS can no longer export projects as .reality or USDZ. Opening export menu results in an empty panel. (170091896)

    StoreKit

    New Features

    • New fields revocationType and revocationPercentage have been added to Transaction. (148858551)

    SwiftUI

    Resolved Issues

    • Fixed: SwiftUI does not surface the latest .userActivity as the current user activity. (163136831)
