Mac OS X Lion Drops Rosetta Support for PowerPC Apps
This is mostly a reminder, but Mac OS X Lion does not include support for PowerPC applications ran through Rosetta. This is important for users who continue to rely on old PPC apps, and this could sway some users decision on whether or not to upgrade to Lion come the public release next month.
Admittedly, the Rosetta-dependent group is probably fairly small in comparison to the wider Mac OS X user base. Rosetta apps are at least 5 years old, which is when Apple made the hardware switch from PPC to Intel CPU’s.
Outside of this and the lack of 32-bit Core Duo/Solo, the Lion system requirements are surprisingly lightweight and forgiving.
Broadly, you have a couple of options. One is to create a dual-boot Mac — one that can boot from two volumes. One volume contains Lion and another runs an older version of the Mac OS. When you need to spend some quality Rosetta time, you boot into the older OS. And yes, this is a pain.
That’s one solution, but it sounds like a hassle to me. Lion looks like a great upgrade, so personally I think I’d just ditch the Rosetta apps.
