How to install

  1. Download VitalSigns here.
  2. Unzip, drag VitalSigns to the Applications folder and run the app.
  3. Activate the widget in the Notification Center.

Requirements: VitalSigns requires OS X 10.11 or later.

VitalSigns doesn't show up in the Notification Center

Go to Apple Menu -> System Preferences -> Extensions. Click 'All' on the left panel and look for VitalSigns on the right. Click the 'Today' checkbox just below it. The widget will now show up in the Notification Center. If it still doesn't, try restarting your system.

Updating from version 1.x

If you have the old 1.x version installed (red icon named 'VitalStats'), a clean installation is highly recommended. You can fully remove the old version using App Cleaner or any other OSX software removal tool. This is not needed if you're already using version 2.x

  • Old 1.x version:VitalStats
  • New 2.x version:VitalSigns

Mac Pro compatibility

VitalSigns is not compatible with old Mac Pro models, although some beta-testers have reported that it works fine with the new Mac Pro (2013).

How to uninstall

If you want to uninstall VitalSigns, you can use App Cleaner or any other software removal tool for OSX. Just drag VitalSigns from the Applications folder to the AppCleaner window, select all files from the list and click 'Remove'. Empty the trash and restart your Mac. VitalSigns is now fully removed from your system.

Update history

  • 2.33 - Fixed a bug that prevented sensor detection after performing a clean installation.
  • 2.27 - Compatibility with macOS Sierra and the new Notification Center style.
  • 2.14 - Minor bug fixes.
  • 2.00 - New version that replaces the old 'VitalStats' 1.x.

Message 'No Temperature Sensors Detected'

Please make sure that you using the latest version (v2.33 - December 1, 2016).
VitalSigns must be located inside your Mac's Applications folder. If you have an old Mac with a slow CPU, sensors may not be detected the first time you run the app. Close VitalSigns and launch it again to solve the issue. If you're still getting this message, restart your Mac.

Message 'No Fans Detected'

If you see this message, you're probably using one of the latest Macbook models. They don't have any fans, so don't worry, just ignore the Fans section.

Fan '0 RPM' indication

The latest Mac models usually stop their fans when the system is idle, or under low workload. The fans will spin again when using resource-intensive applications.

Some temperature readings seem a bit high/low

Some temperature sensors may give false readings. This has been confirmed by an Apple Engineer I talked to recently. You may want to choose another sensor for that component, or simply ignore the reading. It usually happens with some Ambient and/or HDD sensors, but it could also happen with any other sensor.

No HDD or GPU temperature reading

Most Macbooks and Macbook Pro's don't have a discrete GPU. They use the CPU integrated Intel Graphics instead. In that case, only the CPU temperature sensor is used. Also, not every Mac has a HDD temperature sensor.

How to choose a different sensor for a system component

Sometimes, you'll see a little gear icon when you hover the mouse over certain components in the setup application. This means that this component has several temperature sensors available to choose from. Just click the gear icon and select your preferred sensor from the list.

Mac App Store distribution

I'd love to distribute VitalSigns through the Mac App Store, but unfortunately, that's not possible. The reason is the sandboxing requirement that Apple enforces since some time ago. Amongst other things, the 'sandboxing' forbids direct access to the machine's temperature sensors.

This means that utility apps that read temperatures like VitalSigns can't make it into the Mac App Store. (There are a few ones available that were lucky enough to be published before the sandboxing requirement came into force, and many others that simply do not provide temperature readings).

If I wanted to distribute VitalSigns through the MAS, I would need to remove the temperature reading stuff, and this would severely hurt the app's main functionality. So I've chosen to distribute it myself.

OSX blocks VitalSigns

VitalSigns is digitally signed with my Mac Developer ID, which means that OSX's Gatekeeper shouldn't complain when you try to run the app for the first time. Just make sure that you have the correct settings in Gatekeeper: Apple Menu -> System Preferences -> Security & Privacy -> General tab, under the header 'Allow applications downloaded from'. Set this to 'Mac App Store and Identified Developers'.

VitalSigns is a clean app, with no adware and no spyware of any kind. Just make sure that you have downloaded it from the link provided on its official website.

Free app? What's the catch?

VitalSigns is free. No ads, no trial period, no limited functionality, no hidden catch. I initially developed it for my own personal use, and later decided to improve it and make it available for anyone.

Although simple and easy to use, VitalSigns is at its core a relatively complex application that took many hours of hard work to develop. If you like it and find it useful, please consider making a donation for the amount you think it's worth. It will certainly help me to keep improving the app in future updates.
