Apple rilascia agli sviluppatori la Developer Preview 2 di OS X Mountain Lion

È passato un mese esatto dalla distribuzione agli sviluppatori della prima preview di OS X Mountain Lion. Da poche ore è stata rilasciata una nuova versione, sempre dedicata ai soli sviluppatori, che andrà a correggere svariati bug che si presentavano nella prima preview.

In questa versione, Apple ha corretto tantissimi problemi, ma ha anche bloccato diverse funzionalità che probabilmente verranno ripristinate nelle versioni successive. In particolare, il Game Center risulta quasi inutilizzabile per alcune limitazioni del sandboxing.

Ecco l’elenco ufficiale dei problemi ancora non risolti.

  • - Installing OS X 10.8 over 10.7.2 or earlier with FileVault turned on may fail
  • - Upgrades over Lion Server will offer to migrate data again in Setup Assistant even though an in place migration has already succeeded.
  • - Entering your Apple ID in the Setup Assistant does not sign into iCloud
  • - Migration does not migrate RADIUS configurations
  • - Creating an iCloud account using a address in the Setup Assistant requires verification before it can be used in Mail, Contacts, and Calendars.
  • - Some Apple menu items such as Restart may not work when a sandboxed app is in the foreground
  • - Twitter accounts added in Developer Preview 1 will need to be re-added after installing Developer Preview 2
  • - The first time an unsigned or unidentified app is launched when “Mac App Store” or “Mac App Store and identified developers” is selected in the Security & Privacy pref pane, the exception mechanism may fail. Subsequent attempts to run the application with an exception will work as expected.
  • - iTunes no longer syncs Notes
  • - Notes shared via Messages may not include note content
  • - After quitting and reopening Messages, the message window is blank. Continuing a conversation will bring the data back.
  • - TextEdit may hang after enabling Documents & Data in iCloud preferences
  • - Screen Sharing in Messages does not work
  • - Screen Sharing sometimes fails when no users are logged in
  • - Mail’s photo browser cannot access the iPhoto library
  • - VoiceOver cannot access the Notification Center on some machines
  • - Documents stored in iCloud cannot be renamed in the open panel by setting an insertion point and typing. The document can be renamed only by overwriting the entire name.
  • - Back to My Mac doesn’t work for the first 5 minutes after rebooting
  • - Find My Mac is not enabled if checked in Setup Assistant iCloud setup
  • - To enable Find My Mac, turn on Find My Mac in iCloud preferences and then close and reopen the preference panel.
  • - DVD Player may not launch after inserting a DVD on some systems
  • - Some Nvidia GPUs limit the resolution on an external HD display to 1280×800
  • - Some AppleScript applets may not run when Gatekeeper is set to Mac App Store or Mac App Store and identified developers
  • - Selecting Open PDF from the Print Dialog displays the message “Error while printing”
  • - Network scanning does not work in Developer Preview 2
  • - The system may hang after several hours when an external drive is connected
  • - After entering your redemption code, the Mac App Store may not show download progress on the Purchases tab. Quitting and re-launching the Mac App Store will show download progress as expected.

Game Center

  • - In this seed, Game Center applications may only access the Sandbox environment. In the Sandbox environment:
    • - Game & Friend Recommendations are not supported
    • - Friends can view games in common but not friends’ other games
    • - Photos are not supported
    • - Email addresses are not verified during sandbox account creation, allowing multiple test accounts to be created
    • - Out-of-network friend requests are not supported
    • - Game matchmaking versioning restrictions are more relaxed
  • - If you’ve never set up a Game Center Sandbox account, you will need to create one. You may continue to use a previously set up Sandbox account. Note that when using Setup Assistant to create a GameCenter account, the account will be created in the Sandbox environment.
  • - To use Game Center in your game on OS X:
    • - You must include the “” entitlement in your Xcode project.
    • - The app must be signed, in order for the entitlement to take effect.
    • - You must install a provisioning profile that enables Game Center for your app.
  • - Code signing, entitlements, and provisioning profiles are all described in detail in Tools Workflow Guide for Mac.
  • - Multiplayer gaming with Game Center between iOS and OS X is not available in this seed.
  • - In the Game Center app, game detail information such as game provider, pricing, etc. is not displayed.
  • - In the Game Center app, search is not functional
  • - The local peer-to-peer GameKit API (GKSession, GKPeerPickerController, and related classes) is not supported
  • - APIs related to in-game UI (GKAchievementPanel, GKLeaderboardPanel, etc) have changed
    • - The new API is not compatible with the previous seed
    • - Games in development must be updated and recompiled
Ricordiamo che attualmente non esiste alcuna beta pubblica di Mountain Lion e che il sistema finale vedrà la luce in estate. Gli sviluppatori potranno scaricare questa preview dal Mac App Store, dopo aver richiesto il loro codice redeem.
