3rd Party Apps

New Issues

Resolved Issues

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


Resolved Issues

• Enabling Dwell Control during an upgrade from macOS Sierra to macOS 10.13 beta no longer blocks the use of the system clock, other menu extras, the Assistive Control, or the Accessibility Preference pane. (32515238)

Apple File System (APFS)

New Issues

• Encrypted APFS volumes can’t be decrypted. Decryption support will be added in an upcoming beta.

Resolved Issues

• Fixed an issue that prevented enabling FileVault on APFS volumes.

Known Issues

  • Unsupported configurations in this seed release:
    • HDD-only Macs currently are not converted to APFS by default.
    • 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.
    • An APFS container on a Fusion drive can have only 1 macOS 10.13 volume.
  • The encryption policy used for unencrypted APFS volumes that are converted to FileVault can cause the system to select the wrong block offset during the encryption process. This issue will be resolved in an upcoming beta, and will require the affected volumes to be re- encrypted. Encrypted HFS+ volumes that have are converted to APFS are unaffected.
  • 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 formattedusing APFS.CloudKit

    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 4.0, 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 connectionResolved Issues

    • Closing and then reopening System Preferences no longer causes the Content Caching service to restart.

    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.


    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.


    New 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.

• Foundation

New Features

  • AddedaschedulingAPItoURLSessionTaskthatallowsbackgroundURLSession clients to schedule tasks in the future, enabling easy background app refresh semantics for apps, watchOS complications, and more. The API also allows developers to update requests before transmission to address cases where the request has become stale when scheduled in the future. Additions include the earliestBeginDate, countOfBytesClientExpectsToSend, and countOfBytesClientExpectsToReceive properties of URSessionTask, and the URLSession:task:willBeginDelayedRequest:completionHandler method of URLSessionTaskDelegate protocol. (27866330)
  • URLSessionTask adopts the ProgressReporting protocol providing a consistent mechanism for URLSession clients to track the progress of URLSessionTask using the new progress property. (30834550)
  • AddedanAdaptableConnectivityAPItoURLSessionthatenablestaskstoautomatically monitor and wait for satisfactory network connectivity, instead of immediately failing with an error when connectivity is unsatisfactory. Additions include the waitsForConnectivity property of URLSessionConfiguration and the URLSession:taskIsWaitingForConnectivity: method of the URLSessionTaskDelegate protocol.
  • Added support for HTTP brotli content encoding to URLSession. By default, HTTP requests contain a br value (in addition to gzip and deflate) for the Accept-Encoding HTTP header, informing the web server that the user agent supports brotli encoding. The web server can send an HTTP body with Content-Encoding: br in the HTTP header to indicate that the content is brotli-encoded. URLSession automatically decompresses the HTTP body data and passes the decoded data back to the client in the same way it does for Content-Encoding: gzip. For binary compatibility reasons, URLSession brotli support is enabled only for apps built using the macOS 10.13 SDK. (27724985)Resolved Issues• Reads and writes on a secure connection that use the new authenticating HTTPS proxy feature of URLSessionStreamTask now work correctly. (31916868)

    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.

Kernel Extension Loading

Known Issues

  • Some third-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.LocalizationNew Features • Hindi localization has been added to macOS.

New Issues

• Wi-Fi password sharing and Personal Hotspot sharing on beta 2 don’t work with devices running beta 1. (32500217)

• Printing documents with headers and footers may result in garbled or blank output, or in the application quitting unexpectedly.

Workaround: Disable printing of headers and footers in the Print dialog. Safari

New Issues

  • Bookmarks in the Favorites Bar or in the Bookmarks Menu may be missing.Workaround: Add the bookmarks back to favorites or to the menu from the Bookmarks Sidebar. To open the sidebar, choose View > Show Bookmarks Sidebar.
  • Switching to full screen video, or scrubbing video in YouTube may result in the video content no longer updating even though audio continues to play.Resolved Issues• Search suggestions now appear in Safari.

    Known Issues

    • Changed the syncing system for Safari Bookmarks and Reading List across iCloud- enabled devices. Please report any bugs.

macOS High Sierra Disponibilità e Data Rilascio

macOS High Sierra sarà rilasciato ufficialmente in Autunno per tutti gli utenti, contestualmente alla presentazione dei nuovi iPhone.

L’aggiornamento software è disponibile al download anche tramite iTunes, ma solo per gli sviluppatori registrati sul sito Apple. C’è comunque un modo (che vedremo di seguito) per scaricare e installare subito questo aggiornamento anche senza essere sviluppatori. 

macOS High Sierra Beta Pubblica Rilascio E Disponibilità

Solo verso inizio Luglio sarà disponibile una Beta pubblica che permetterà agli utenti “normali” di provare il nuovo sistema operativo di Apple.

Il motivo dell’attesa è semplice: macOS High Sierra Beta è instabile, con bug e problemi che non permettono di usarlo quotidianamente.

Se però sei un utente coraggioso e vuoi provare subito macOS High Sierra Beta, incurante dei bug e dei problemi, ecco come fare per provarlo sul tuo Mac ORA!
