![]() Show Me Moreįinally, although I don’t feel the need to monitor them in real time, I like to occasionally see the temperatures of my MacBook Pro’s components and the speeds at which the internal fans are spinning, both of which are available (where else?) in iStat Menus’ drop-down menu. Here’s another example: If I see my CPU spike to 70 or 80% (from its usual “light workload” average of 5 to 20%), I click iStat Menus in the menu bar, which shows me which apps are hogging up the processor so I can take appropriate action. iStat’s drop-down menu shows me which processes are using the most RAM. Then, I quit any and all RAM-hogging apps (I’m looking at you, Photoshop CC) I can live without for the moment. So, if I see that I’m running low on available (free) RAM, I click iStat Menus in the menu bar to display the apps currently using the most RAM in its drop-down menu. The reason this is so important is that I can see when CPU, RAM, or network activity are higher-than-usual and take steps to address the issue before it becomes a problem.įor example, when RAM gets full everything slows down. ![]() iStat Menus shows me (left to right) Memory used/free CPU % CPU history network activity and network history, using very little space in my menu bar. So, my current RAM usage and availability current and historical CPU load and incoming and outgoing network traffic are always visible in the menu bar, using only a tiny bit of my precious screen real estate. Show Me the Important Stuffįor me, the most important metrics are CPU, RAM, and network usage, which I monitor in real time with iStat Menus ($18). See, I take it upon myself to monitor the handful of critical bits of information about my Mac that help me insure it continues to run smoothly. But I also have to give some of the credit to myself. I have to give some of the credit to Apple, which has made macOS more reliable and stable with each release. But, I really can’t remember the last time my Mac crashed or froze and caused me to reboot. I occasionally have to force a recalcitrant program to quit (Command + Option + Esc). And, it often runs for weeks (or months) without a hiccup (or a restart or shut down for that matter). It usually runs 24 hours a day, seven days a week.

IStats is a command-line tool that allows you to easily grab the CPU temperature, fan speeds and battery information on OS X.
