I am a little embarrassed to announce the release of maxwell-0.5.1 which fixes make install problems with the 0.5 release.
Maxwell is a S.M.A.R.T. drive reporting tool for Mac OS X. It is a command line application, so is usable from scripts and from cron. It can give you all kinds of useful information about your drive as well as informing you of the pass/fail status of your ATA drives Self-Monitoring, Analysis and Reporting Technology.
Maxwell, a SMART reporting tool for Mac OS X is now available for testing. Maxwell can check your drives for impending failure and give you details on the drives current status.
