Asset Trustee 6.6. The application helps IT staffs manage their hardware and software inventories, and the latest version adds cross-platform software compliance reporting. This new feature allows administrators to figure out if they’ve deployed more licenses than they’re allowed or even if they’ve purchased more licenses than they really needed. Asset Trustee 6.6 gathers detailed license information from every laptop, desktop and server connected to the network, no matter which OS they’re using, and generates reports from the data. The application runs in Mac OS 9 and Mac OS X.
