Mac: Tracking your various sensors on your Mac is easyenough with a system monitor, but if youre looking for a free and simple option, VitalSigns dumps info from various sensors into your Notification Center.
VitalSigns isnt a complete system monitor, instead, it just tracks a small handful of details: temperatures, fans, and memory.
For the temperatures, you’re able to pick which sensors are shown for which boards, but otherwise, theres not much in the way of customization.
Considering VitalSigns is free, thats not a bad thing, and if youre just looking for a quick way to keep an eye on a few system details, it does its job.
