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.

Pro Tools 7.4.2pr is a free download for all Pro Tools 7.4 owners. You will need your Pro Tools HD 7.4 iLok license, Pro Tools LE 7.4 authorization code, or Pro Tools M-Powered 7.4 iLok license to authorize Pro Tools 7.4.2pr.
