BridgeHelper 3.0
MacMan has added support for these new CPUs to xnu-1699.24.23 (AKA the 11.3.0 Darwin kernel shipped in OS X 10.7.3) and we're happy to announce it's release.
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.
