Under OS 10.4 (Tiger), the AU version of MachFive 1.22 public beta appears to be compatible with Live, Garage Band and other AU hosts, and we are proceeding with on-going AU testing. However, the MachFive 1.22 public beta is not compatible with Logic 7.01 under Tiger. Logic users must upgrade to Logic 7.1 to successfully run MachFive 1.22 under Tiger.

Please see our Tiger compatibility page for full 10.4 compatibility info.
