Note: The Adobe Flash Player 10.1 release, expected in the first half of 2010, will be the last version to support Macintosh PowerPC-based G3 computers. Adobe will be discontinuing support of PowerPC-based G3 computers and will no longer provide security updates after the Flash Player 10.1 release. This unavailability is due to performance enhancements that cannot be supported on the older PowerPC architecture.
