Mac OS X Snow Leopard Installation Process Revealed And Golden Master Build Seeded To Developers

Earlier this week, it was reported that Mac OS X Snow Leopard build 10A432 has been designated Golden Master status, which means it is ready to be released to manufacturing for public launch. AppleInsider has posted details about some of the changes and enhancements to the Snow Leopard installation process:

  • Although Rosetta and QuickTime 7 are both included on the Mac OS X 10.6 installation DVD, both are designated as optional installs by default. However, if Mac OS X 10.6 is being installed on a Mac that contains a registration key for QuickTime 7 Pro, the installer will install QuickTime 7 automatically.
  • Options to “Erase and Install” and “Archive and Install” are no longer present in the Mac OS X 10.6 installer. According to those familiar with the software this was done for convenience, so that users do not accidentally erase and install their Mac OS X 10.5 Leopard partitions. However, “Erase and Install” remains available through Disk Utility, which is also included on the installation DVD.
  • A reinstallation will not affect your Mac OS X version number. In other words, reinstallation of Mac OS 10.6 on a Mac that contains Mac OS X 10.6.1 (when it becomes available) will not overwrite any new components delivered by 10.6.1. So when the reinstall is complete, you will still be running Mac OS X 10.6.1. This will save considerable time.
  • If a power outage occurs, installation will pick up from where it left off.
  • To prevent the Blue Screen error that plagued some users when upgrading to Mac OS X 10.5, a software compatibility check is included that has a list of known “bad” apps, and disables them. Those programs are moved to an “Incompatible Software” folder.
  • Unlike Mac OS X 10.5, you cannot install Mac OS X 10.6 Snow Leopard on computers where the hard drive reports a S.M.A.R.T failure.
  • Installation initially triggers a large chuck of data to be copied from the installation DVD to the user’s primary hard drive. The bulk of the installation is then managed from the hard drive, speeding up the installation process considerably. After a successful installation, that large chunk of data is automatically removed.

In other Snow Leopard related news, the Golden Master build 10A432 has been seeded to developers for final testing before release. The download weighs in at 6.1GB and is available to all the developers registered with ADC (Apple Developer Connection) as Premier or Select members. Mac OS X Snow Leopard is available for preorder on Amazon, Snow Leopard is priced $29 and Snow Leopard Family Pack (5-user) is priced $49.
