What is Mac OS X Snow Leopard (Universal) - 10.6 Developer Preview Seeds?

Mac OS X Snow Leopard Developer Preview Seeds were released between June 2008 and early 2009.

In March 2020, with only minor modifications, builds 10A096 and 10A190 were found to install successfully on certain PowerPC machines (G4/G5). Apple stated officially that PowerPC macs would not be supported, once Snow Leopard was released for retail sale, making these early Developer Previews of particular interest to the Apple PowerPC enthusiast community.

A highly motivated community on MacRumors have been thoroughly testing the PowerPC compatible Snow Leopard  builds, since April 2020. Community efforts to compile Apple Open Source Projects, fix bugs and backport system components are ongoing. Several usability fixes and installation instructions are detailed in a robust WikiPost: Here

Locating the Installer log

When you install Mac"OS"X, the Installer saves a log of the installation. To see the log, open Console (in the Utilities folder in the Applications folder), click Show Log List, click the disclosure triangle next to /var/log, and then select install.log.

The Installer can’t repair your disk

If a message says the Installer can’t repair the disk, you may need to erase it. This deletes all the files on your disk.

NOTICE: If you erase the destination disk, everything on the disk—your user accounts, network settings, and all of your files and folders—will be deleted. Before you erase your disk, quit the Installer and back up any files you want to keep by copying them to another disk. When you’re ready to erase the disk, open the Installer and follow the instructions in “Erasing and formatting your disk”.

The installation wasn’t successful

If you were unable to install Mac OS X, try the following:

  • Disconnect any external devices you don’t need during installation.
  • Eject any cards from manufacturers other than Apple.
  • Use Disk Utility to repair your hard disk.

After disconnecting unnecessary devices or ejecting any cards, start up from the Mac OS X Install Image. Select your language and click the forward arrow. To open Disk Utility, choose Utilities > Disk Utility. Select the disk on which you want to install, click First Aid, and then click Repair Disk. After repairing any problems, quit Disk Utility and click Continue to try installing again.

If you were still unable to install Mac OS X, try erasing your disk before installing Mac OS X. To erase and install Mac OS X, see the instructions in “Erasing and formatting your disk”.

Mac OS X installation was interrupted and you can’t start up your computer

Restart your computer. Your computer may start up using the last system you were using. If it doesn’t and you have another Mac OS X system installed on your computer, restart your computer while holding down the Option key to select a startup disk.

If your computer doesn’t start up this way, insert the Mac OS X Install Disc in your computer and hold down the C key while restarting. Open Startup Disk preferences and select a startup disk.

Mail, iCal, and Address Book work with Microsoft Exchange Server 2007 SP1. The Snow Leopard Developer Preview contains read-only access.
