ProTools 7.4.2 was released by Digidesign to add compatibility with Mac OS 10.5 "Leopard." At this time, Digidesign has tested versions 10.5.3 and 10.5.4 as compatible. While Mac OS 10.5.5 seems to also be working with ProTools 7.4.2, testing is not complete.

NOTE - earlier version of Pro Tools, including version 7, 7.3 and 7.4 are NOT compatible with Mac OS 10.5 Leopard.
