SixtyFourSwitcher Makes Mac OS X 10.6 run faster by toggling the 64-bit kernel

SixtyFourSwitcher 1.3

Copyright 2009-2011 Nick Zitzmann.

SixtyFourSwitcher is a preference pane that makes it easy for users to switch between booting using the 32-bit version of the Mac OS X kernel and the corresponding 64-bit version. The 64-bit kernel is internally faster than the 32-bit kernel due to its improved caching & improvements in the ABI, but the 32-bit kernel has better kernel extension compatibility than the 64-bit kernel.

SixtyFourSwitcher requires Mac OS X 10.6 or later, as well as a 64-bit CPU, such as the Intel Xeon or Core 2 Duo.

Mountain Lion users: This preference pane is obsolete in Mountain Lion and later, since Apple removed the 32-bit kernel from the OS. I'll keep this download up for a while for the people still running Snow Leopard or Lion.
What's new in version 1.3:

    Whitelisted a number of older Macs for users running Lion & later. This update does nothing for Snow Leopard users.
