Digidesign has announced that Apple Logic Pro 7.2 is fully compatible with Pro Tools|HD Systems using version 7.1 of the DAE (Digidesign Audio Engine). To install the Pro Tools files needed to support Logic Pro 7.2, you must download Pro Tools HD 7.1cs4 or higher, which is available free to all Pro Tools HD 7 owners from the Support section of the Digidesign Web site
Logic Pro 7.2 is currently available from Apple.
Important Note: Although Logic Pro 7.2 is a universal version that runs natively on both Intel- and PowerPC-based Mac systems, Digidesign hardware and Pro Tools software are not yet compatible with Intel-based Mac systems. Pro Tools|HD hardware currently requires a PowerPC-based Mac system or a Windows XP system.
Customers using Pro Tools HD 6.9.x and earlier software must use Logic Pro 7.1 or earlier.
