Keep an eye on CPU, GPU, memory temperature, observe fan speeds (rpm) and get hdd disk IO statistics with mac system monitor. Sensors Plug-in helps iStatistica being the most advanced system monitor on the App Store.
Macs are powerful devices, and with the introduction of the custom Apple silicon M1 Macs and MacBooks, it has become more imperative that you manage the background apps and monitor power consumption.
Don’t get us wrong, the M1 SOC is fast and is the fastest of the chips that we’ve ever seen, but that doesn’t mean that you should leave everything to the computer and not do anything as it will consistently deliver poor results and keep on getting slower over time. However, using a system monitor brings a lot of benefits, and they are:
- In-depth monitoring of apps and processes.
- Maintaining a smooth user experience.
- Helps terminate unresponsive and unwanted tasks and applications.
Are you currently taking full advantage of all the techy help you can get?
If you are not sure, I’m glad you are here. As a Mac geek, I have been testing some system monitoring tools and I’m happy to share my favorites with you.
Quick jump to…
Let’s start with the standard: Activity Monitor
Your Mac comes with a built-in system monitoring application known as Activity Monitor. It is excellent for closing unresponsive applications and seeing real-time CPU, Network, Disk status or Energy usage. So, how do you access the Activity Monitor? – Follow the steps below to get the activity monitor running for you.
- Firstly, Go to your “Applications” folder and then to the “Utility” folder.
- Then double-click on the “Activity Monitor”, which will bring up a window.
- This is the Activity Monitor app, and here you’ll see five tabs and a list of entries that changes every few seconds. The Tabs contain the following information – CPU, Memory, Energy, Disk Usage and Network.
Note: The Activity Monitor shows you real-time usage and power consumption. It also allows you to close and terminate all unresponsive tasks or tasks, hogging up too much performance.
Is the built-in Activity Monitor good enough?
The Activity Monitor is a decent app from Apple and is ideally suited to beginners. However, if you want to have extra control over what you’re doing and the processes running, you would have to opt for the third-party solutions listed below.
The Activity monitor helps you by displaying the main processes and the percentage load on the CPU and GPU. It can also force-quit any unresponsive application and help recover your Mac to a normal running state. However, there are many features and information that it misses or hides due to Apple’s clutter-free and simple design idealogy. Hence, third-party applications are better alternatives for the program.
Therefore, the built-in Activity is popular with beginners and casual users, while professionals use 3rd-party apps with more functionality and readily available data.
Try a better monitor: iStat Menus

iStat Menus use a menu bar integration method to display all the information. This can lead to problems such as a cluttered menu bar or accessibility concerns. However, you can lay these concerns to rest as iStat Menus is highly customizable. You can choose what to display on the menu bar and what to hide on the menu bar. You also have the option to hide the icons from your menu bar temporarily and customize the update frequency so that the icons aren’t disturbing.
It also allows the app’s accent colours and personalizes the icons according to your liking and preferences. The total amount of customizations it provides is immense, and you can change the menu bar colours, borders, and even the slightest of details in the shade of the drop-down that highlights the graphs and other information. The interface highlights how changing the colours will affect the app and the menu bar, and with this much customization at hand, iStat Menus becomes the go-to option for a distraction-free and clean activity-monitoring app.
Performance Monitoring
As we have already discussed, the CPU and GPU tab helps you manage your processes and activities. Finally, the memory tab enables you to manage RAM consumption to improve performance and responsiveness all around the UI.
However, this is the basic that iStat Menus is capable of. iStat Menus can also display various graphs and infographics of your workload so that you can manage and learn about your usage and ample insight on how your apps behave. The app is also quite a haven for developers and can help them check and stress test their app performance and requirements on the Mac.
Notifications and Weather Information
Mac Temperature Monitor App
Finally, iStat Menus also provides many customization options for what notifications you want to receive. The notification feature allows you to have reports every time your Mac hits a specific condition or issue. For example, it helps you by notifying if your Mac heats up, overuses the CPU, or saturates the memory with background apps.
It also features a built-in weather information widget to help you monitor your area’s current and upcoming weather condition. However, some of the weather tool features are locked behind a paid upgrade which is a bummer considering it is handy. The module displays the daily forecast along with the maximum and minimum temperature based on your preferred units. Oh, and if you are a weather buff, you also get to see the dew point, wind’s speed and direction.
Oh, and the cherry on the cake is that the custom notifications settings and preferences also work with the weather module, which means if you are working on your Mac and the weather suddenly turns grey and stormy, a message pops up right away notifying you of the condition.

Unobtrusive and small utility which will keep a close eye on your Mac's processor and notify you when its temperature goes above a pre-defined safe value
What's new in Temp Monitor 1.4.8:
- Fix bug that causes two instances of menu/helper app.
- Fix open at login issues.
- Minor bug fixes and improvements.
Although most of Apple's Macs come with highly efficient cooling designs, there are times when intensive processing tasks such as video rendering and audio design put an enormous strain on the CPU.
If you need to stay on top of the situation and to keep a close eye on your Mac processor's temperature, it is a good idea to have an app capable of monitoring it one look away at all times.
Support for customizable overheat temperature
Temp Monitor is a macOS application specifically designed to watch a Mac processor's temperature very closely and display it in the menu bar in the form of a text- and icon-based status item.
More precisely, Temp Monitor runs in the background and will let you know when the CPU's temperature reaches dangerous levels, thus enabling you to pause highly intensive processing tasks and resume them at a later time to protect your Mac's integrity.
The CPU temperature which triggers Temp Monitor to display an overheat notification can be customized via the app's settings window. From there you can also set Temp Monitor to launch on login and choose the default temperature unit it uses.
Notification Center integration and automatic logging of all overheat alerts
Furthermore, the Temp Monitor utility displays audio and visual notifications via macOS' Notification Center feature, and it they are by default set to be alerts which will not go away until manually dismissed, an excellent idea for when you are away from your Mac and the CPU temperature goes above the safe threshold.
The temperature warnings are also added automatically to Notification Center's notifications tab, for later reviewing of all past alerts when and if needed.
Low-key CPU temperature monitor for Macs
As a downside, when clicking the 'Configure Notifications' in Temp Monitor's Settings window, you are directed to System Preferences' main screen instead of the Notifications preference pane.
To summarize it all, the Temp Monitor app is an unobtrusive tool which will alert you when your Mac overheats, and the perfect utility to help you log all instances when the processor goes beyond a temperature which might be dangerous for both your Mac and yourself, if you're using a MacBook or MacBook Pro.
