There are several sections and the first shows CPU usage. However, there is so much more to see by clicking anywhere in this menu bar display, more than will fit on my MacBook screen. This is all very useful information and you can see system stats at a glance.

There is a fan icon and fan speed, network or internet upload and download speeds, battery percentage and time remaining. Following the second icon is the memory used and free, memory temperature and percentage used. For example, it can show the CPU usage as a percentage and the temperature in degrees (Celcius in my case, but probably Fahrenheit in the US). Start it and several icons and numeric information appears at the top of the screen on the right.

(Get it from the website, not the App Store.) This free app is different to Activity Monitor in several ways and the most obvious is that it runs in the menu bar rather than in its own window.

Eul menu bar activity monitorĮul is an activity monitor for the Mac that enables you monitor the resources the Mac and apps are using.
You don’t need to be an expert to use it, but it helps. These panels provide a lot of useful information, but you do need a bit of technical knowledge to understand the contents. For example, you can choose the number of items to show using the most CPU or RAM, or set an activation level for network activity so trivial accesses are ignored. When each of these is clicked, a panel displays detailed information and this has more configuration options. This is great and you can monitor system usage without putting any extra workload on the system. With just the CPU, RAM, network and battery modules enabled, Stats used hardly any power at all on my M1 Mac.

The update interval can be selected from 1 to 30 seconds.
Network activity shown by the Stats appĮach of the menu bar modules has several options and labels can be shown or hidden, colored or monochrome, aligned left, right or centered. However, if you want to see fan speeds, temperatures and so on, you can enable it.
Activity monitor mac os Bluetooth#
The developer warns that the sensors and Bluetooth modules require more power than the others and this is just the way that Apple Silicon Macs work. In the app’s settings you can choose what modules to show in the menu bar, and this includes CPU, GPU, RAM, disk, sensors, network, battery and Bluetooth. If you are wondering whether the CPU is overworked, the memory is running out or the disk is nearly full, you can see it without interrupting what you are doing. The menu bar system stats are always there, always visible and do not get in your way, unlike the large Activity Monitor app window on the desktop. Stats shows system activity in the menu bar It shows brief information in the menu bar itself and detailed information when it is clicked. Stats is a free and lightweight system monitor for the menu bar on an Apple Mac and is an alternative to Activity Monitor. They work on new Apple Silicon Macs and older Intel Macs and are free. The two alternatives here use much less CPU, memory and energy and they can be permanently active. I run it, take a quick look at the data and quit as soon as I can. Its energy usage is also high and this will inevitably cause faster battery drain. On my M1 MacBook Air it can be 8 or 9% CPU. On my old Intel MacBook Air, Activity Monitor can use as much as 24% CPU activity. If your Mac is a few years old, the demands placed on the system by Activity Monitor and the latest version of macOS are too great to leave it running all the time. Resource usage is most noticeable with older Mac that have less powerful Intl CPUs, less memory and ageing batteries than with brand new Macs. It’s not a problem for the newest M2 powered Macs, but it is noticeable on the original entry level M1 MacBook Air. Run it and check the tabs to see for yourself if you have an Intel Mac. On older and less powerful Macs, Activity Monitor uses a lot of CPU, memory and energy. There is no doubt that Activity Monitor is a great app, but it is not one that you would want to leave running on the desktop all day because it uses system resources and desktop space. You can easily see technical information like CPU, memory, disk, network and even energy (battery) usage.
There are many questions you might need the answer to when using your Mac and Activity Monitor can answer all of them. Is the CPU busy? Is memory or disk space running short? Which apps are using the most CPU and RAM? Why is a file taking so long to download? Is it the network speed? What is the time remaining on a MacBook’s battery? Activity Monitor on the Apple Mac is a useful utility for seeing what is going on under the macOS user interface, but it is too demanding of resources.
