Here's a partial list of the software and hardware we've identified as currently incompatible, on some level, with Mac OS X 10.5 (Leopard): Check VersionTracker for the latest releases.
Now that the final code has been available for several days, stable, Leopard-compatible apps should start popping up rapidly. Though most developers had access to pre-release builds of the OS, new builds often broke previous compatibility work, meaning developers had to start over. Do not expect them to work out of the gate.Īs for third-party applications, most actively developed programs that are not-yet Leopard-compatible will see updates in the coming days and weeks. The bottom-line: Add old third-party utilities slowly and carefully test each one as you go. This not only allows you to have a problem-free experience directly post-update, but also helps in isolating the issue (if you add third-party components back one by one). Most potentially offending items will be eliminated, and you can add them back as you see fit. The surefire way to avoid these issues from the get-go is to follow our recommendation ( 1, 2) to use an Archive and Install or Erase and Install process when installing Leopard. Incompatible third-party hardware devices can cause similar issues, as they often interact with kernel extensions (located in /System/Library/Extensions). Many incompatible third-party system software add-ons (especially those that reside in /System/Library or /Library) can cause significant issues such as an inability to finish the boot process or blockage of general system services. a product causes other system issues, including conflicts with other applications, in inability to login/startup or something else.a product loses functionality completely.a product loses some level of functionality.Incompatibility can mean many different things. There are a number of third-party software and hardware products that are incompatible with Mac OS X 10.5 (Leopard).
