[quote]Digidesign is pleased to announce the immediate availability of a pre-release version* of Pro Tools® software that provides expanded Mac OS X 10.5.3 Leopard compatibility for many Pro Tools users. Pro Tools 7.4.2pr software is provided as a convenience for Mac-based Pro Tools 7.4 users who may wish to begin their transition to Leopard before a fully tested and qualified version of Pro Tools becomes available.
Pro Tools 7.4.2pr software is available as a download only, and requires Mac OS X 10.5.3. Pro Tools 7.4.2pr is not compatible with earlier versions of Leopard.[/quote]
