app4mac has announced CheckUp 2.5 for Leopard-based Macs, adding an updated user interface, Snow Leopard compatibility and other options. Along with a better system view, there are now options for exporting graph data, for choosing the default application for a document and for using any folder in the duplicates checking tool. app4mac has added an integrated uninstaller as well.

CheckUp monitors a Mac's disk, memory, CPUs and network connections as a background process. User-set conditions trigger an alert, like defective RAM or a soon-to-fail hard disk. It can monitor multiple Macs via a TCP/IP connection. CheckUp can also check system capabilities and track system and network performance.

CheckUp 2.5 requires Mac OS X 10.5 or higher. The upgrade will ship next week and is available as a beta until then. The software costs €30, about $40.
