Apple ha rilasciato la terza developer preview di OSX 10.8 Mountain Lion: questa versione caratterizzata da numero di build 12A178q è disponibile per gli sviluppatori iscritti regolarmente al programma Mac Developer.
Questa versione corregge moltissimi bug e sistema molte lacune trapelate durante l’uso della seconda beta; nonostante questo rimangono molte problematiche aperte e vi elenchiamo per chi mastica un po’ di inglese le note dei bug ancora presenti:
“Known Issues
- On systems with FileVault enabled, canceling the restart to the Mountain Lion Developer Preview 3 Installer may leave your system unable to present a password dialog at boot time. You
can repair the problem by holding down command-R to boot to the Recovery OS and then using Disk Utility to unlock and Repair your volume.
- Installing OS X 10.8 over 10.7.2 or earlier with FileVault turned on may fail
- Pre-Lion FileVault user accounts are not supported in this Developer Preview
- Some Apple menu items such as Restart may not work when a sandboxed app is in the foreground
- iTunes no longer syncs Notes
- Mail’s photo browser cannot access the iPhoto library
- Back to My Mac doesn’t work for the first 5 minutes after rebooting
- DVD Player may not launch after inserting a DVD on some systems
- Most help topics are unavailable in this Developer Preview
- In the Recovery HD:
- Some icons may be missing
- Network Utility’s Lookup pane does not work
- Time Machine restoration via a AFP share does not work
- Restoring from a Time Machine backup via AFP does not work
- Migration from a Time Machine backup that excludes paths such as /System may yield an unusable system
- Brightness settings may change unexpectedly after reboot
- Display brightness may be dim after sleep or reboot
- If Mail is hidden at logout time, it may not be correctly relaunched during a subsequent login but will appear to be running
- Java applets may not work in Safari
- QuickTime screen recordings may produce corrupted videos or cause an exception when run on machines with NVDIA graphics
Game Center
- In this seed, the Game Center application will view Production data by default. Games in development will be programmatically switched to use the Sandbox server environment
- No Top Games are displayed on the Me tab and no game recommendations are shown on the Games tab
- To use Game Center in your game on OS X, 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
- The local peer-to-peer GameKit API (GKSession, GKPeerPickerController, and related classes) is not supported”
