Entwickler können ihren Mac im Developer Portal von Apple als Entwicklergerät registrieren und erhalten dann automatisch über den App Store die neuesten Entwicklerbetas. Ist das bei euch der Fall sollte das neue Testrelease ab sofort automatisch verfügbar sein.

Hier die Änderungen von macOS High Sierra im Detail:


New Features

• AddedAVRoutePickerViewtotheAVKitframeworkandAVRouteDetectortothe AVFoundation framework for enabling users to choose the route for playing content when multiple routes are available. Use AVRouteDetector to determine if multiple routes are available when route detection is enabled. If multiple routes are available, use AVRoutePickerView to present an interface for the user to choose the routes. The functionality of AVRoutePickerView is disabled in this beta. (32822468)

Resolved Issues

Time Machine is enabled for macOS High Sierra 10.13 beta 3 and later, and the space for snapshot is now freed correctly on APFS volumes. (33006905)
Resetting the NVRAM on a Mac with a bootable APFS partition no longer prevents that partition being used as the startup partition. (33013161, 32991435)

3rd Party Apps

Resolved Issues
Microsoft Outlook 15.35 and later now launch on macOS 10.13 beta.

Apple File System (APFS)

Resolved Issues
Fixed an issue that prevented enabling FileVault on APFS volumes.
Fixed an issue where the encryption policy used for unencrypted APFS volumes that are converted to FileVault could cause the system to select the wrong block offset during the encryption process. Affected volumes need to be re-encrypted. Encrypted HFS+ volumes that have are converted to APFS are unaffected.
Fixed an issue where an APFS container on a Fusion drive could have only 1 macOS 10.13 volume.
Fixed an issue where APFS systems with FileVault enabled could not reset their password with iCloud. (32818928)

Known Issues

• Unsupported configurations in this seed release:
• HDD-only Macs cannot be converted to APFS. (32360337)

• Some iMacs with 3TB Fusion drives and BootCamp may be unsupported for use with APFS. (31851687)

• APFS support for Mid 2012 Mac Pro will be included in an upcoming release. (32109298)

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.
Encrypted APFS volumes can’t be decrypted. Decryption support will be added in an upcoming beta.
The X11 window manager cannot be used on APFS formatted installation of macOS. (31507129)
Systems may panic during app installation. (32990178)


Known Issues
CloudKit does not support unsigned long long values with the high-order bit set. (30567424)
ApplicationsthatuseCKModifyRecordsOperationshouldspecifyanappropriate value for CKModifyRecordsOperation.isAtomic. if your client is compiled against watchOS 4, operations enqueued against the default CKRecordZone have new behavior because atomic is true by default. If the operation hits a “preflight” failure (most commonly, a network issue uploading a CKAsset, or a malformed CKRecord), the entire operation is canceled. (30838858)

Content Caching > Share Internet connection

Resolved Issues

• Fixed an issue where tethered iOS devices used only Wi-Fi when both Wi-Fi and USB Ethernet are available. (32140835)


Known Issues

Known Issues

• When copying files the progress indicator may persist after the copy completes. (32681094)

Workaround: Log out of your account and log back in, or restart your Mac. Foundation

Known Issues

• Topreservebackwardscompatibility,iOS11beta3removedtheNSURLSessionempty string behavior for suppressing the sending of HTTP headers that was introduced in beta 2. (32959604)

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 needs 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.
Third-party apps that do not rely on the macOS-provided media frameworks may not properly handle these new formats.


Known Issues

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


Resolved Issues
Reinstalling macOS 10.13 from the Recovery OS no longer requires using Disk Utility to unlock your FileVault-encrypted volume.
Resolved an issue where systems with less than 4 GB of RAM may hang when installing applications. (32589377)

A new setting in preferences, “Smart quotes and dashes in rich text documents only”, enables toggling the behavior for plain text documents. In addition, it can be changed on a per-document basis from the Edit > Substitutions menu.

Touch Bar

New Features

• In beta 3 and later, touch event processing for the Touch Bar has been modified to reduce accidental actions by ignoring touches lasting more than 1.5 seconds. In addition, the active area of a button or segmented control is slightly inset from its edges so that touches very close to either the left or right side are ignored. (32990374, 32990587)

Note: If you discover problems with either of these heuristics and your usage patterns, file a bug with a subject that starts with “Beta 3 Touch Bar Heuristic Issues: “.
