Today’s Macs are engineered like no other. Built-in to most Macs are a number of sensors which are used to take the Mac’s temperature. The CPU, battery, disk drive, and more. Unfortunately, the Mac doesn’t warn us when what’s under the hood becomes warmer than it should. We may hear the fan kick in, but not much more.
By using the Temperature Gauge app we can get a quick reading on the Mac’s temperature status, for CPU, battery, memory, even the palm rest area. Install Temperature Gauge and watch the Menubar icon which displays temperature or other information.
Click the icon to reveal details of each component on your Mac.
Temperature Gauge runs in the background but can display an alert if your Mac gets too hot. It also displays the current, maximum, and minimum values for each of the fans in your Mac.
One look at the graphs in Temperature Gauge gives you a quick look at temperatures for CPU, battery, RAM, and the Mac as a whole.
