During the summer of 2008, I was using my MacBook Air outside on a very hot (102°F in the shade) day when I noticed that the laptop seemed to have slowed down to the point that it was almost unusable. Fortunately, I had installed iSlayer's iStat, and I was able to tell at a glance that one of the cores of the Core 2 Duo processor had shut down.
Sure enough, a quick look around the Web pointed out that other MacBook Air owners were running into similar problems in "warm" conditions. Cooling off the MBA resolved the issue (and made me a lot cooler, too!), and I've never had the problem since. That one occurrence taught me the value of a tool like iStat, so the application has been on my Macs ever since.
Now comes iStat Menus 3, the latest version of the venerable Mac monitoring application. The company name has changed -- it's now Bjango -- but the product still remains a useful tool for those of us who like to keep an eye on the internal workings of our Macs. I recently bought iStat Menus 3 to install on a new i7 iMac, so here are some of my first impressions of the app.
