SixtyFourSwitcher


SixtyFourSwitcher 1.1

Did you know that there’s a quasi-hidden feature in Snow Leopard that will make your Macintosh run faster across the board at the expense of some backward compatibility? Or are you an Xserve or Mac OS X Server user that has to revert to the older kernel in order to use older software?

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. Why would anyone want to do this? Because the 64-bit kernel is considerably faster than the 32-bit kernel, with the downside being that it is not compatible with older kernel extensions, and software that relies on the old extensions.

SixtyFourSwitcher requires Mac OS X 10.6 or later. SixtyFourSwitcher is a two-way (Intel 32 and Intel 64) universal binary.
