Matterform Media (http://www.matterform.com) has released version 2.0
of Sonar, a real-time file-security monitor for the Mac. The update
is now compatible with Mac OS X 10.5 (“Leopard”) and is expected to
work just fine with the upcoming Snow Leopard.
Sonar is a utility that displays real-time information about changes
made to a user’s hard drive. It can be used in monitoring untrusted
applications downloaded from the internet and for debugging system
slow-downs caused by runaway applications that write too frequently
to the disk.
Licensed users of previous Sonar versions can download and use Sonar
2.0 at no cost. New licenses are available for purchase for US$17.95.
