BridgeHelper 4.0 - Enhanced 10.7.4 Kernel for Ivy Bridge CPUs

As part of Apple's commitment to Open Source, they make the current Mac OS X kernel source available about a week after releases at As there are no Ivy Bridge Macs yet, MacMan has added support for Ivy Bridge CPUs to xnu-1699.26.8 (AKA the 11.4.0 Darwin kernel shipped in OS X 10.7.4) and we're happy to announce it's release.

BridgeHelper 4.0 will replace your 10.7.4 system kernel with MacMan's 10.7.4 Darwin kernel with Ivy Bridge CPU support. The installer is now available at

PLEASE NOTE:  Ivy Bridge CPUs and chipsets are not currently supported natively by Mac OS X. We can't recommend Ivy Bridge systems yet, as there is no official support. Hence, please don't view this as buying advice. We don't recommend using a patched kernel for the long-term. The vanilla kernel is a much more desirable solution for a stable system.
