Release Notes for macOS 10.13 Build 17A306f

macOS High Sierra

macOS High Sierra

macOS 10.13 Developer Preview Seed 3 is pre-release software. Do not use this pre-release software in a commercial operating environment or with important data. You should back up all of your data before installing this software and regularly back up data while using the software.

Notes and Known Issues

General

Known Issues

  • Resetting the NVRAM on a Mac with a bootable APFS partition prevents that partition being used as the startup partition.
    Workaround: Use Startup Manager to select the APFS partition as the boot partition. To open Startup Manager, hold the Option key immediately after rebooting the Mac.

Resolved Issues

  • Time Machine no longer fails to remove snapshots on disks formatted APFS.

3rd Party Apps

Resolved Issues

  • League of Legends no longer quits unexpectedly on Mac models from 2012 and later.

Apple File System (APFS)

New Issues

  • Systems may panic during app installation.

Resolved Issues

  • Decrypting a FileVault volume is now supported.
  • Resolved an issue where an APFS container on a Fusion drive can have only 1 macOS 10.13 volume.
  • Enabling FileVault no longer selects the wrong block offset during the encryption process.

Known Issues

  • Unsupported configurations in this seed release:
    • HDD-only Macs cannot be converted to APFS.
    • Some iMacs with 3TB Fusion drives and BootCamp may be unsupported for use with APFS.
    • APFS support for Mid 2012 Mac Pro will be included in an upcoming seed.
  • There is a known issue where APFS systems with FileVault enabled cannot reset their password with iCloud.
  • Resizing APFS containers is currently not supported in Disk Utility.
    Workaround: In Terminal, use the diskutil tool to resize APFS containers.
  • Some third-party applications may not correctly recognize volumes that are formatted using APFS.

CloudKit

Known Issues

  • CloudKit does not support unsigned long long values with the high-order bit set.

Content Caching > Share Internet connection

Known Issues

  • Tethered iOS devices use only Wi-Fi when both Wi-Fi and USB Ethernet are available.
    Workaround: Disable Wi-Fi on the tethered iOS devices.

FaceTime

Known Issues

  • Live Photo support will be added in an upcoming beta.

FileVault

Known Issues

  • There is a known issue where APFS systems with FileVault enabled cannot reset their password with iCloud.

Resolved Issues

  • When iCloud recovery is enabled on an encrypted APFS volume, Password Reset no longer shows an error that iCloud recover is not enabled.

Finder

Known Issues

  • When copying files the progress indicator may persist after the copy completes.
    Workaround: Log out of your account and log back in, or restart your Mac.

HEVC and HEIF Images

Known Issues

  • macOS 10.13 adds HEVC and HEIF decode capability. In order to display HEIF image files or HEVC videos captured on iOS 11, your Mac will need to be updated to macOS 10.13.
  • The specific hardware and software requirements for HEVC and HEIF are detailed in the WWDC 2017 presentations covering these new technologies. Depending on the capabilities of your Mac and the needs of your content, AVFoundation may use a software-based HEVC encoder which typically has longer encoding times. Further fine- tuning of the encoding quality will occur in subsequent seeds.
  • 3rd party apps that do not rely on the macOS-provided media frameworks may not properly handle these new formats.

iCloud

Known Issues

  • When you initially sign in to iCloud on macOS 10.13, you may find that some services do not sync correctly. If this happens, please sign out of iCloud and sign back in. This should allow your account to sign in fully and sync all services.

Installer

New Issues

  • Systems with less than 4 GB of RAM may hang when installing applications.
  • During macOS High Sierra installation or during the first user login after installation, input methods may fail to load. Rebooting your Mac once will cause input methods to load normally.

Kernel Extension Loading

Known Issues

  • Some 3rd party apps may not fully handle instances where their kernel extension is denied user consent to load.
  • Kernel extensions blocked in early boot do not display an alert.

Localization

New Features

  • Hindi localization has been added to macOS.

Known Issues

  • Some text may not be localized to the selected system language.
