The programs listed below have compatibility problems with Mac OS X 10.5 Leopard, ranging from minor incompatibilities that do not affect core functions to major problems that prevent use. This list is compiled from developer statements, and where possible, we've included links to the official statements, information on expected updates, and other notes. (Some developers appear to have been caught by late Leopard changes made between the last seed release developers received and the official release available now. Developers did not have access to the official release version until October 26, the day that it became available to consumers, which delayed compatibility testing.)

For notes from MacInTouch readers on their experiences with various programs running on Leopard, including problems and possible workarounds, see our Leopard Reader Reports.

Yikes. Maybe I'll wait till after new years.
