Monit Widget is a modest, but ambitious, Notification Center Widget for monitoring your Computer.

Limitations due to AppStore sandboxing and other Known Issues:

○ An AppStore App is not allowed to read system sensors (SMC), so we cannot show detailed temperatures and other sensor data such as fan-speed.

○ An AppStore App is not allowed to read all processes on the system. This means that the Top-3 App List will not necessarily contain the processes that are currently using the most resources. The List will however show the applications that are using the most resources.

○ MONIT will underreport Memory usage for Applications in the Top-3 List that spins of sub-processes which we are not allowed to read. In practice, MONIT is quite accurate given the sandbox restrictions it operates under, but for certain applications it will underreport. If you compare with Activity Monitor, you should compare with "Real Memory" and aggregate memory usage of sub-processes.

○ The thermometer uses an Apple API that does not seem to work properly on older Macs. On MacBooks from 2015 and later it appears to work fine.


● The Widget connects to an external host to get your Public IP-address. This is the only reliable way to obtain your address. No data is sent, only read.

● The Top-3 App List shows App CPU usage normalized (0-100%).

● Temperature for your Hard Disk(s) and Battery is displayed according to your settings for Measurement units in System Preferences > Language & Region. If you have selected Metric you get temperature in Celcius otherwise in Fahrenheit.


Release Notes:

◉ New: Colors. The new white background in MacOS Sierra Notification Center makes it a challenge to create a nice UI that is easy to read at a glance. A monitoring widget needs a dark background, in our opinion. We therefor use a background color that we think best suits the widget, but perhaps not Notification Center as a whole. We hope you'll give it a chance.

◉ New: Persistent UI. Expanded rows will remain expanded on restart

◉ New: Thermometer for overall system temperature. Please note that an AppStore App is not allowed to read sensor data which means we cannot show detailed temperatures. To do that, we would have to create a non-sandboxed "helper app" which you had to download outside of the App Store. We want to play within the rules, so Monit's thermometer is limited to displaying the total thermal state of the system. We hope you agree with us that it is still quite useful. There are 4 thermal levels; normal, fair (fans running), serious and critical. See also known issues

◉ New: Top-3 Lists of Applications using most Memory and CPU. Click an App in the list to switch to that App. Open Activity Monitor by clicking its icon. See known issues for limitations

◉ New: S.M.A.R.T. Status and Temperature for Disk's that support SMART

◉ New: Power Usage in Watt when running on Battery. Click the label to show a popup with other electrical units

◉ New: More information in popup menus and a new Uptime popup menu

Love this, very good resource monitor - Shows CPU, Memory, Disk, Battery (if applicable), and Network activity in a very simple UI. Each category can be expanded for additional details. The only thing I wish it had was temperature in the expanded CPU category.

Review by usn.mustanger

Doesn’t work - Wish I could review the functionality, but it doesn’t work for me on my 13” MBP running 10.11. Only the Monit title bar ever shows in the notification center, and trying to manually results in a “Monit quit unexpectedly” dialog every single time. I’ve yet to be able to see this app in action.

Almost there! - Just add numerical value for CPU temp, also add an option to switch from Farenheit to Celsius and it will be perfect!

Review by Doctorgizmo

Love it when it doesn’t freeze. - This is a handy and informative widget but it frequently freezes and the only solution to unfreezing it is to remove it from the Notification Center and then reinstall it. At first I thought it might be freezing due to my old Mid-2010 Core 2 Duo MacBook Pro having a slow CPU but it also freezes on my Mid-2011 Quad Core i5 iMac as well as my Mid-2012 Dual Core i5 MacBook Pro. All my Macs are running 10.11.6 El Capitan with recent clean installs. I like it when it works, but having to remove and reinstall to get an updated readout defeats the purpose of a Notification Center Widget.

Great APP - I am a heavy user of Parallels on my Mac. Due to a lot of the programs I use through Parallels, I like to know where my memory, disk, and CPU usage is being used. I know I can recieve this information from Activity Monitor, however it is MUCH easier to click the taskbar and have MONIT display the information immediately. The most recent update also included a darker background color to make up for the white taskbar color from OSSierra I highly recommend trying this app out.

Awesome app but needs a light mode - I think this is a super useful widget to have in the notification tray but really think that there should be a light mode, while the current blue background does look nice it doen’t match Sierra’s new notification centers design and sticks out like a sore thumb. 5 stars if a white mode is added

Awesome utility! - Been using it for a while now and it does pretty much everything I need it to. It is tucked out of the way in the notification tray but when I need it I can select the item I am interested in. Very cool interface. CPU, Memory, Disk and battery at glance. Want more detail? No problem just click on the meter and voila! Need more? In the CPU widget click on the icon and Activity monitor opens up so you can kill or do what you need. Very happy camper here :)
