Thursday, April 19, 2012 at 5:12AM |
Print Article Today Apple released OS X 10.8 Mountain Lion - Developer Preview 3 (wow, that's a mouthful). It's available now to all Mac developers and like previous builds is downloaded through the Mac App Store (using a Redeem Code).

As reported by MacRumors, there is still a long list of known bugs:
- 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.
- Migration from a Time Machine backup that excludes "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 NVIDIA graphics
Unfortunately, due to the developer NDA I can't go into more detail, however as we move towards WWDC 2012 (6th June), you can expect a steady flow of leaked information. Watch this space.
