Coolant 是一款Mac上优秀的系统资源监控提醒工具，可以自动监控系统资源的使用情况，当不足时进行提醒，很不错！
软件介绍
Coolant lets you know when apps get power hungry before they drain your battery or overheat your Mac.
That's why we created Coolant, a menu bar app that lets you know when an app is using an excessive amount of CPU or memory so you can close it and save battery power. With Coolant you're never blindsided with a quick-draining battery, you can continue to be productive for hours more.
