Sonar is a security tool that reports file change activity on your hard drive in real-time. It can show you every time a program changes a file on your hard drive. Sonar can be useful for several purposes:
- Run Sonar before installing a new program so you can see exactly what gets installed. Then you can remove it later if necessary.
- Use Sonar to troubleshoot Spotlight-related slowdowns on your computer. Sonar will show you highly active files that you might want to consider adding to the Spotlight exclusion list to avoid frequent re-indexing.
- Developers can use Sonar to monitor how frequently their software writes to the hard drive. Developers can use this information to optimize their program's hard drive usage.
What's new in this version:
Sonar 2.0 is now compatible with Mac OS X version 10.5 (Leopard). It is expected to remain compatible with the soon-to-be-released Snow Leopard, Apple's new OS scheduled to be released later this year.
