Lion Eats Software
With the release of Mac OS X 10.7 "Lion", Apple have withdrawn support for PowerPC applications (Rosetta). Fortunately, only a handful of our more venerable titles are affected. We have worked feverishly to produce compliant (Intel) versions of these titles, and have released free patches where possible.
If you order a replacement CD or full retail package, please mention that it is for the Lion upgrade.
