– The new Pro Tools HD 7.4.1 now supports Mac OS 10.5.1 and runs with HD 7.4 iLok license. This is however just the first part of the Leopard update cycle and supports only 10.5.1 on selected Mac Pro models (not 10.5.2). At this point, we recommend using 7.4cs2 with Tiger 10.4.9 and wait with Leopard and 7.4.1 until more Macs, plug-ins, virtual instruments, chassis and video options are supported. Pro Tools LE and M-Powered are not yet Leopard compatible.
