# macOS Sonoma 14.6 Release Notes

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

## Overview

Overview The macOS 14.5 SDK provides support to develop apps for Mac computers running Sonoma 14.6. The SDK comes bundled with Xcode 15.4, available from the Mac App Store. For information on the compatibility requirements for Xcode 15.4, see Xcode 15.4 Release Notes. ARKit Resolved Issues Fixed: iPhone and iPad apps on Apple Silicon Macs quit unexpectedly when initializing ARSkeletonDefinition.  (128038936) Core Spotlight Resolved Issues Fixed: iPhone and iPad apps on Apple Silicon Macs quit unexpectedly when invoking -[CSSearchableItemAttributeSet setActionIdentifiers:].  (128039095) Finder Resolved Issues Fixed: Home Videos unexpectedly sync as Music Videos to iPod nano (7th generation).  (94899119) Video Subscriber Account Resolved Issues Fixed: iPhone and iPad apps on Apple Silicon Macs quit unexpectedly if VSOpenTVProviderSettingsURLString is referenced.  (113562872) Video Toolbox Resolved Issues Fixed an issue and now on Apple Silicon, if width or height is greater than 4096 columns or rows and content uses 4:2:0 chroma subsampling and 8-bit depth, the hardware decoder driver will reject it and a software decoder will be automatically selected to ensure artifact-free decoding. AVC (H.264) content at level 5.2 or lower can be handled by the hardware decoder. Content that otherwise conforms to level 5.2 but is high frame rate (e.g. 4k at 100 or 120 fps) is labelled level 6, 6.1 or 6.2 and is also handled by hardware. If content is 10-bit, 4:2:2 or 4:4:4, the hardware decoder will be used.  (122448862)
