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.

What's New

Version 1.3:
  • Whitelisted a number of older Macs for users running Lion & later. This update does nothing for Snow Leopard users.


  • Mac OS X 10.6 or later
  • 64-bit Intel CPU
